I saw on you tube how to build this and bought the parts here on desertcart. after building the controller I can now use NINA advanced sequence to controll my roof in my observatory, so that means when I'm sleeping my scope is taking pictures and when it is done NINA sends a signal to this Arduino and it relays it to my motor controller and it closed my roof.... pretty neet... Review: Arduino boars are great for small projects - UI use my R3 to build a remote compass so i could tell which way my rooftop antenna was pointing after our spring wind storms. Solid build quality and easy to use. ## Features - This is the R3 version of the UNO SMD - Gateway board to the entire Arduino line - Create electronic projects using the Arduino system - Available Arduino Shield boards add greater functionality ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B007R9TUJE | | Best Sellers Rank | #275 in Computer Motherboards | | Brand | Arduino | | Chipset Family | AVR | | Compatible Devices | Personal Computer | | Compatible Processors | ATmega328P, ATmega16U2 | | Customer Reviews | 4.8 out of 5 stars 646 Reviews | | Graphics Card Interface | Integrated | | Item Dimensions L x W x H | 3.15"L x 2.28"W x 0.91"H | | Item Weight | 37 g | | Main Power Connector Type | 2.1mm Barrel Jack | | Manufacturer | SparkFun | | Memory Clock Speed | 16 MHz | | Memory Storage Capacity | 32 KB | | Mfr Part Number | ABX00173 | | Model Name | Arduino UNO REV3 SMD | | Model Number | ABX00173 | | Number of Items | 1 | | Number of Ports | 1 | | Platform | Linux | | Total Usb Ports | 1 | | UPC | 845156603565 | ## Product Details - **Brand:** Arduino - **Compatible Devices:** Personal Computer - **Compatible Processors:** ATmega328P, ATmega16U2 - **Graphics Card Interface:** Integrated - **Main Power Connector Type:** 2.1mm Barrel Jack - **Memory Clock Speed:** 16 MHz - **Memory Storage Capacity:** 32 KB - **Model Name:** Arduino UNO REV3 SMD - **Platform:** Linux - **RAM Memory Technology:** DDR ## Images ![Arduino Uno Rev3 SMD [A000073] Microcontroller Board - ATmega328P, 16MHz, 32KB Flash, USB & PWM Support, Ideal for DIY Projects, STEM Learning, Robotics, and Prototyping - Image 1](https://m.media-amazon.com/images/I/61kNkTT8upL.jpg) ![Arduino Uno Rev3 SMD [A000073] Microcontroller Board - ATmega328P, 16MHz, 32KB Flash, USB & PWM Support, Ideal for DIY Projects, STEM Learning, Robotics, and Prototyping - Image 2](https://m.media-amazon.com/images/I/61uWVnNn+JL.jpg) ![Arduino Uno Rev3 SMD [A000073] Microcontroller Board - ATmega328P, 16MHz, 32KB Flash, USB & PWM Support, Ideal for DIY Projects, STEM Learning, Robotics, and Prototyping - Image 3](https://m.media-amazon.com/images/I/61wln7c9B3L.jpg) ![Arduino Uno Rev3 SMD [A000073] Microcontroller Board - ATmega328P, 16MHz, 32KB Flash, USB & PWM Support, Ideal for DIY Projects, STEM Learning, Robotics, and Prototyping - Image 4](https://m.media-amazon.com/images/I/51BX+C7Cg5L.jpg) ![Arduino Uno Rev3 SMD [A000073] Microcontroller Board - ATmega328P, 16MHz, 32KB Flash, USB & PWM Support, Ideal for DIY Projects, STEM Learning, Robotics, and Prototyping - Image 5](https://m.media-amazon.com/images/I/61KFvohJ3EL.jpg) ## Questions & Answers **Q: Arduino UNO smd v3. Vs arduino uno v3 .What is the difference** A: The difference between the two Arduino UNO module is the ATMEGA MPU chip. The Arduino UNO uses the DIP version of the chip and the ARDUINO SMD version uses a surface mount ATMEGA chip. Function wise, there is no difference. The only advantage on using the ARDUINO UNO with a DIP style ATMEGA chip is you can replace the chip, while the ARDUINO UNO SMD version you cannot replace the chip.

No cable. **Q: Are these items suitable for brilliant 14 year old boy?** A: Absolutely! I recommend also purchasing a solderless bread board and a set of"3 x 40P 20cm Dupont Wire Jumper Cable 2.54 1P-1P Male-Male/Female-Female/Female-Male "Note that you might also want to purchase a 9v power supply (look at the "Frequently Bought Together" list). **Q: What is the xtal frequenty?** A: Crystal Oscillation is a t 16.000 MHz. ## Customer Reviews ### ⭐⭐⭐⭐⭐ build a controller for a roll off roof observatory *by G***N on October 7, 2025* I bought this to build a controll board to operate my roll off roof observatory with NINA.
