# Arduino Uno R3 Shield Template pU2K ## Description Template for Arduino Uno R3 Shield. Include an official pinout so you will always know Arduino names, the alternative roles of pins, which one is SDA, or SCL, etc. On PCB you can find the 3D model of the Arduino Uno R3 itself along with the board outline on the silkscreen. #Arduino #Uno #Shield #Template #project-template #project ## Project Details - **Owner:** iannunes - **Created:** 1/7/2025 - **Last Updated:** 1/7/2025 - **Visibility:** Public ## Key Components ### U1 — [Arduino Nano](https://www.flux.ai/vasyl/arduino-nano~0ia.md) - Manufacturer Part Number: Arduino Nano - Part Type: Evaluation Board - Datasheet URL: https://media.digikey.com/pdf/Data%20Sheets/Arduino%20PDFs/A000005.pdf - Manufacturer Name: Arduino **Pins:** - +5V [pin 27] - 3V3 [pin 17] - A0 [pin 19] - A1 [pin 20] - A2 [pin 21] - A3 [pin 22] - A4 [pin 23] - A5 [pin 24] - A6 [pin 25] - A7 [pin 26] - AREF [pin 18] - COM/GND [pin 4] - COM/GND__1 [pin 29] - D0/RX [pin 2] - D1/TX [pin 1] - D10 [pin 13] - D11/MOSI [pin 14] - D12/MISO [pin 15] - D13/SCK [pin 16] - D2 [pin 5] - D3 [pin 6] - D4 [pin 7] - D5 [pin 8] - D6 [pin 9] - D7 [pin 10] - D8 [pin 11] - D9 [pin 12] - RESET [pin 3] - RESET__1 [pin 28] - VIN [pin 30] *The full schematic, PCB layout, bill of materials, and interactive design are available at [https://www.flux.ai/iannunes/arduino-uno-r3-shield-template-pu2k~47](https://www.flux.ai/iannunes/arduino-uno-r3-shield-template-pu2k~47).* --- *Generated from [https://www.flux.ai/iannunes/arduino-uno-r3-shield-template-pu2k~47](https://www.flux.ai/iannunes/arduino-uno-r3-shield-template-pu2k~47)*
