# Arduino Uno R3 Shield Template ## 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:** pedrobronbus - **Created:** 1/8/2025 - **Last Updated:** 2/10/2025 - **Visibility:** Public ## Key Components ### ARDUINO NANO — [ARDUINO_NANO](https://www.flux.ai/jecstronic/arduinonano~2x.md) - Datasheet URL: https://www.snapeda.com/parts/Arduino%20Nano/Arduino/datasheet/ - Manufacturer Part Number: ARDUINO_NANO - Manufacturer Name: Texas Instruments Inc. - License: https://creativecommons.org/licenses/by/4.0/ - Part Type: Integrated Circuit **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 [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 [pin 28] - VIN [pin 30] ### BT1 — [Battery Holder 1 Cell DIP AA](https://www.flux.ai/vasyl/battery-holder-1-cell-dip-aa~gak.md) - License: https://creativecommons.org/licenses/by/4.0/ - Voltage: 1.5V - Datasheet URL: https://www.keyelco.com/userAssets/file/M65p28.pdf - Part Type: Battery Holder - Manufacturer Part Number: 2460 - Manufacturer Name: Keystone Electronics **Pins:** - NEGATIVE [pin N] - POSITIVE [pin P] ### BT2 — [Battery Holder 1 Cell DIP AA](https://www.flux.ai/vasyl/battery-holder-1-cell-dip-aa~gak.md) - License: https://creativecommons.org/licenses/by/4.0/ - Voltage: 1.5V - Datasheet URL: https://www.keyelco.com/userAssets/file/M65p28.pdf - Part Type: Battery Holder - Manufacturer Name: Keystone Electronics - Manufacturer Part Number: 2460 **Pins:** - NEGATIVE [pin N] - POSITIVE [pin P] ### DS18B20 — [DS18B20+](https://www.flux.ai/adrian95/ds18b20plus~f15.md) - Datasheet URL: https://www.analog.com/media/en/technical-documentation/data-sheets/ds18b20.pdf - License: https://creativecommons.org/licenses/by/4.0/ - Manufacturer Name: Analog Devices Inc./Maxim Integrated - Manufacturer Part Number: DS18B20+ - Part Type: Sensor **Pins:** - DQ [pin 2] - GND [pin 1] - VDD [pin 3] ### SIM800L — [SIM800L Module](https://www.flux.ai/adrian95/sim800l-module~ja6.md) - Datasheet URL: https://components101.com/sites/default/files/component_datasheet/SIM800L-Datasheet.pdf - Manufacturer Part Number: SIM800L - License: https://creativecommons.org/licenses/by/4.0/ - Manufacturer Name: Simcom - Part Type: Module **Pins:** - DTR [pin 11] - GND [pin 6] - MIC- [pin 9] - MIC+ [pin 10] - NET [pin 1] - RING [pin 12] - RST [pin 3] - RXD [pin 4] - SPK- [pin 7] - SPK+ [pin 8] - TXD [pin 5] - VCC [pin 2] *The full schematic, PCB layout, bill of materials, and interactive design are available at [https://www.flux.ai/pedrobronbus/arduino-uno-r3-shield-template~8g](https://www.flux.ai/pedrobronbus/arduino-uno-r3-shield-template~8g).* --- *Generated from [https://www.flux.ai/pedrobronbus/arduino-uno-r3-shield-template~8g](https://www.flux.ai/pedrobronbus/arduino-uno-r3-shield-template~8g)*
