AZDelivery ESP32-DevKitC NodeMCU WiFi WLAN CP2102 ESP32-WROOM-32D IoT 2-In-1 Microcontroller Bluetooth Module Development Board compatible with Arduino including E-Book!

This is a veritable powerhouse of a microcontroller board, with both WiFi and Bluetooth, plenty of RAM and flash memory, digital, analogue pins (and touch inputs), together with hardware features like random number generation, hall effect sensor, etc. I can pretty much guarantee that no-one will actually use ALL of the capabilities. Running at an impressive 240 MHz, it is no slouch, but it can also go into a deep sleep when extremely long life on battery power is needed. The documentation on the manufacturer's site (Espressif) runs into thousands of pages (more than 800-page pdf hardware manual alone). Despite all this, it is as easy to get beginner level code running (blinking LEDs, etc.) in the Arduino environment as it is for its little brother, the 8266, or any other board such as the Arduino Uno or Nano. There is an error in the silk-screen printing on the board where a pin is labelled 'GND' where it should be 'CMD'. It is worth keeping away from this end of the board anyway as, apart from the 5V pin if needed, most of the IO pins are reserved for internal use to access the 4 megabyte flash memory. 3.3 volt power and ground are available at the other end of the board. If you need an accurate pinout, just look up 38-pin Devkit-C on the Internet. I keep a printed copy at hand as the print on the board is not only difficult to read, but nowhere near as informative as my printed crib sheet. For example, take the silk-screen pin IO22. My sheet tells me that is pin 39, GPIO22, PWM is available, it is also the SCL pin for the default hardware I2C bus and the RTS pin for the first serial port. I can also see that it is not one of the nine touch-sensitive pins. For breadboarding, I have joined together two boards, but have removed the power bus from one of them. This results in plenty of access to the ESP32 pins with the added bonus of a central 2 wire-bus (ideal for I2C) running underneath. See photo. Conclusion: I favour the 8266 in the guise of the D1 mini boards for most projects, but as soon as the project needs a bit extra, like more than one analogue input, or bluetooth, or just a bit of extra speed, that is when the ESP32 comes in. For just a small extra cost this solves the problem with little or no change to the source code. The only improvement I can think of would be a version akin to the D1 mini, where the surplus pins are removed and both sides of the board are used to result in a smaller module with no loss of facilities.

ESP32 - My Favourite Tinker Board Once again, AZ Delivery provided a high quality item and a competitive price and delivery to the UK was very quick. Just a couple of days. Some other reviewers seem to have had issues with the markings for the pins. Having checked the yellow legged version I recieved, everything is marked up perfectly. Meybe this issue has now been addressed? Having used various boards based on the Atmel chips and several Raspberry Pi variants, I was a little curious how this would perform and can honestly say, the ESP32 is now my favourite tinker board. It’s just so versatile. There is a lot that this thing can do – IoT, WiFi scanning, messaging…it can even play Doom! I’ve only started to scratch the surface of the available functionality but has so many possibilities. For a quick test I tried the Wifi scanned example. Loaded the board config into the Arduio IDE, uploaded and fired up the serial monitor. Straight away, I was seeing all the WiFI available in my area. To test connectivity with other devices, I set up a BMP280 and AZ-Devlivery SH1106 OLED screen on a breadboard and tweaked the Adafruit BMP280 sketch to output to the screen With a quick little sketch the results were fast and accurate. Now I can go on to expose these values over the web or post them in a message queue or allow queries over WiFi or Bluetooth. So much this little board can do! My only gripe is that it came pre soldered with a male header. The format of the board makes it too wide to fit on a single breadboard and with the pins exposed underneath, there is no indication what the layout is on the bottom of the board. My preference would have been for the header on the top of the ESP32 dev board. But that will be an easy change for me to make. Overall, I love this little board and look forward to exploring its capabilities. There is a lot of information, documentation, tutorials and support on the web for it, too.

I’ve used ESP8266/NodeMCU for a while, and ESP32 is a step up in power and functionality. This board from AZ-Delivery will take care of pretty much anything a maker/hobbyist can throw at it. It would even give a good account of itself in professional/industrial applications. Although newer than the ESP8266, support for ESP32 is growing, and it is easily integrated into the Arduino environment, with plenty of libraries and examples to get a user up and running quickly. Worth checking which pin the built-in LED is on, Pin 1, I think (usually Pin 2 on this type of board). Supported by the popular Blynk IoT platform, advanced WiFi/IoT projects are easily handled by this board. As well as a serious step up in performance, with a dual-core 32-bit processor and 4M Flash, a key addition to the ESP32 over the ESP8266 is Bluetooth, offering both Classic and LE versions. Examples in Arduino work first time, and there are great articles at Random Nerds Tutorials for the beginner. Took about 10 minutes to get values from a light level sensor streaming to a BT terminal on an Android phone. I love it when stuff just works! Once I’d seen how easy this board was to use in Arduino, I decided to try programming in Python, or rather the embedded version, MicroPython. This is where the extra Flash memory comes in useful. Again, there is good support for this board at micropython.org, and it works well with popular IDEs such as Thonny and uPyCraft. Once again, the guys at Random Nerds Tutorials have some great step-by-step articles to get you started.

I bought these as I was undertaking a project for my home automation set up. They seemed particularly good value, especially as I got them using Prime. The delivery was next day, and the price for the three of them was around 21 quid - about the same as I could find on AliExpress. They arrived well-packaged in a cardboard box, and each one was sealed in it's own anti-static bag and set in a small block of foam to protect the pins. I use Home Assistant on a Raspberry Pi 4, and I flashed these using the ESPHome integration within Home Assistant. Instead of plugging these directly into the R/Pi, I plugged them into my workstation PC as the R/Pi is not really very accessible - although it works a treat over the network. All went seamlessly.. and was straightforward using the ESPHome web UI. One small problem which I encountered was initially trying to connect to the ESP32 device via my USB port - when trying to connect via the ESPHome web UI, it kept bring up an error message saying "failed to open serial port" - this is not the serial port on your PC, but the serial port on the ESP32 board.. I overcame this by holding down the small 'boot' button, whilst clicking the 'connect' icon on the ESPHome web UI.. and it then connected, and I was able to install my yaml files. After this, I could then easily undertake Over The Air updates via the WiFi network without issue. I hope this helps somebody. 👍🏻 Would I buy them again??? Yes, without doubt. A good value item, that can provide endless fun if you are a fettler! EDIT: I did buy them again!! Got another three to use so I can place some custom sensors and controllers around the house. I'll be using one to control my Rayburn Range cooker, both via a web interface and a Nextion screen which will be wall attached next to the cooker. Another will be used as a replacement boiler controller using digital temperature sensors to replace the old (and failing) electro-mechanical ones. This offers so much more flexibility for programming and efficiency of running - again, this will be web-enabled so I can get the data through via Home Assistant using my phone.

Review of ESP Wroom 32 AZDelivery ESP32-DevKitC NodeMCU WiFi WLAN CP2102 ESP32-WROOM-32D IoT 2-In-1 Microcontroller Bluetooth Module Development Board Compatible With Arduino including E-Book! The item arrived within 3 days of ordering from the UK Amazon site. The packaging was adequate, the part arrived in its own individual box inside a sealed metallised plastic envelope. Packaging and actual PCB were not damaged. The build quality of the board is very good for the price, there are no sloppy soldered connections, excess solder flux or solder/metal particles sputtered around. The RF side of the PCB seems to follow the general guidelines for best signal/noise with no traces or ground plane under the antenna. The mounting hole diameter is 2.54mm with a range of 0.5mm to 0.7mm from the edges of the PCB so no room for error in mounting pillars The board works straight out of the box with relevant boards and libraries loaded in the Arduino IDE. The boards can be downloaded from github/espressif . The board type to be selected is the ESP32 Dev Module The Arduino IDE already has ESP32 boards available so only the “esp32” keyword is needed in the libraries' search interface. I was able to connect to the module and run the example Hall Sensor code within 15 minutes. Moving a magnet over the metal shield the module displays the variance of magnetic flux, so slow changing magnetic field does not seem to have an effect. I have attached a snip of the serial plotter showing changes in the magnetic field intensity while I was moving the magnet. The radio seems to be working well also and I was able to run a few examples proving some functions of the WiFi module. So far I have not found anything negative about this module, I have had it run continuously for about 24 hours and the board did not reset or freeze. One point that I like in particular is the USB connections that has four soldered joints. Most micro B connectors have a two-point soldered connection for mechanical bracing and these connections often fail. But for this item being a development module I will appreciate this “reinforced” USB connector since there will be a lot of connecting/disconnecting.

I purchased these as I started to get into microcontroller programming beyond the capabilities of the Picaxe. This development kit is well supported on the Arduino IDE with just about anything you could want in sample programmes. Though the smaller format ESP32 boards may be more attractive, this is my "go-to" as I learn to use various components as it has a lot of pins available. Of course, it has wifi and bluetooth capability. I have always had good results from AZ Delivery regardless of the components I have purchased.

This is an ESP32-Wroom even though it doesn’t say on the metal case. It will do classic blue tooth which is what I needed. Well packaged and speedy delivery.

1.) The pins are incorrectly labelled. The ground pin next to the 5V in is not a ground pin. Took ages on web to discover this was an issue and to use ground 5 pins from the 5v. (2.) The wifi is next to useless unless the board sits on top of the router. Move it 2 metres away and the wifi connection is lost. Shame. Returning.

Kanon ! Dom funkar kanon till Home Assistant som det är tänkt
