Teyleten Robot ESP32-S3-N8R2 ESP32-S3 Development Board Wi-Fi + BLE MCU Module Integrates Complete Wi-Fi and BLE Functions 3pcs

Items arrived as described, easy to setup and program, work great.

It took me a while to figure this all out. Hope this helps you. From factory, it comes with flash all blank. Needs to have circuitpython and/or bootloader installed. It has 2 usb ports. One is labeled "com" and the other "usb." First connect to the "com" port, and use esptool.py to flash the "combined.bin" UF2 bootloader, that is downloadable from the circuitpython download page for this device. Then swap the cable to the "usb" port, and the UF2 bootloader will make a removable drive available to your computer. Copy the circuitpython UF2 file, which is also downloadable from the circuitpython site for this device. The device will reboot, and you'll have the full circuitpython experience. If you need to re-flash at a later time, to upgrade circuitpython, press Reset, and then quickly while the light is purple, press Boot. This will take you to bootloader mode, which will allow you to replace the circuitpython UF2 file.

This Teyleten Robot ESP32-S3 development board pack offers great value for hobbyists and developers alike. With Wi-Fi and BLE capabilities, it's incredibly versatile for a range of IoT projects. The compact size and easy-to-use design make it a solid choice for beginners and experienced users. While the documentation could be more extensive, the online community provides ample support. Overall, a good option for those looking to experiment with the ESP32-S3 platform.

Just like others, I like this device. I am able to set the color of the neopixel LED so I know that status without having to use a separate display for my use case. Thanks for the posts here on some details as the documentation is lacking (hence the 4 stars). Hoping the vendor or the user community for this device can provide a better place. Has anyone used the OTG feature and how to configure the "correct" USB-C port for it(?left or right when looking at it from the top with the mounted components). I would like to connect it to a serial device with USB as input. Thanks! To enable and use the neopixel, here is the code I used including a function I created to further simplify it's use within the Arduino code. #define ESP32S3_NEOPIXEL_N 1 //number of pixels? #define ESP32S3_NEOPIXEL_P GPIO_NUM_48 //on-board neopixel i/o pin #include <Adafruit_NeoPixel.h> Adafruit_NeoPixel neo = Adafruit_NeoPixel(ESP32S3_NEOPIXEL_N,ESP32S3_NEOPIXEL_P,NEO_GRB+NEO_KHZ800); int board_pixel = 0; char neo_R = 127; char neo_G = 127; char neo_B = 127; void neoColor(char r, char g, char b) { neo_R = r; neo_G = g; neo_B = b; neo.setPixelColor(board_pixel, neo.Color(r, g, b)); neo.show(); } //use neo.begin() within the arduino setup() section //I just use my own function newColor( r, g, b) to change colors as needed.

Everything works exactly the same on this board as the Espressif official development board, at half the price! The pinouts of these two boards are also the same, however this board (Teyeten Robot) has a 0.1" wider pins stance than the official board, or one hole wider on a breadboard. The only issues that I ran into was the need to download the CH341SER drivers to allow Arduino IDE / PlatformIO / ESP IDF to communicate to the board via Serial USB. Other than that, everything was a breeze to set up and use. The onboard JTAG USB debugging is a life saver and is much easier than having to use a dedicated ESP-PROG debugging tool. Overall, great product that I would highly recommend! All 6 boards that I have used and tested were perfect. Looking forward to getting more development boards in the future from this company... you just can't beat their pricing.

There is absolutely no schematic diagrams or any documentation for the board it may be low cost but it is pretty useless unless you have some documentation there is no way to tell what is wired to what in reality it is a waste of money. Also they have the USB connectors labeled wrong which is not surprising.

These boards have performed as expected without failure. Had no trouble getting them soldered and they made me look like a pro. I have used them for game emulators with tft displays as well as RGB matrix displays. Excellent project board.

The boards work, and seem okay on 3v. I had some issues and wasted many ours trying to troubleshoot GPS and mmwave sensors. running 5v I had tried 1k on the RX but pin was still over loaded and not reading. touching the wire seemed to give it enough capacitance to get data, but it was still problematic. 10k leg and self grounded I was finally able to get data from GPS and mmwave 5v sensors. I wanted these for the live debug and serial separation. but then found they do not fit the standard expansion boards. not sure I will have much use for them.
