# 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:** jaztin - **Created:** 2/8/2024 - **Last Updated:** 2/9/2024 - **Visibility:** Public - **Stars:** 1 - **Copies:** 14 ## Key Components ### BATT1 — [1070TR](https://www.flux.ai/jharwinbarrozo/1070tr~eit.md) - Manufacturer Name: Keystone Electronics - Manufacturer Part Number: 1070TR - Voltage: 9V - Datasheet URL: https://www.keyelco.com/userAssets/file/M65p5.pdf **Pins:** - - - + ### J1 — [Pin Header 01x06 2.54mm Vertical](https://www.flux.ai/vasy_skral/pin-header-01x06-254mm-vertical~jyw.md) - License: https://creativecommons.org/licenses/by/4.0/ - Part Type: Connector **Pins:** - Pin_1 [pin 1] - Pin_2 [pin 2] - Pin_3 [pin 3] - Pin_4 [pin 4] - Pin_5 [pin 5] - Pin_6 [pin 6] ### J2 — [Connector 01x08 0.100](https://www.flux.ai/vasy_skral/connector-01x08-0100~q3l.md) - Part Type: Connector - License: https://creativecommons.org/licenses/by/4.0/ **Pins:** - Pin_1 [pin 1] - Pin_2 [pin 2] - Pin_3 [pin 3] - Pin_4 [pin 4] - Pin_5 [pin 5] - Pin_6 [pin 6] - Pin_7 [pin 7] - Pin_8 [pin 8] ### J3 — [Pin Header 01x10 2.54mm Vertical](https://www.flux.ai/vasy_skral/pin-header-01x10-254mm-vertical~1nl.md) - Part Type: Connector **Pins:** - Pin_1 [pin 1] - Pin_10 [pin 10] - Pin_2 [pin 2] - Pin_3 [pin 3] - Pin_4 [pin 4] - Pin_5 [pin 5] - Pin_6 [pin 6] - Pin_7 [pin 7] - Pin_8 [pin 8] - Pin_9 [pin 9] ### J4 — [Connector 01x08 0.100](https://www.flux.ai/vasy_skral/connector-01x08-0100~q3l.md) - Part Type: Connector - License: https://creativecommons.org/licenses/by/4.0/ **Pins:** - Pin_1 [pin 1] - Pin_2 [pin 2] - Pin_3 [pin 3] - Pin_4 [pin 4] - Pin_5 [pin 5] - Pin_6 [pin 6] - Pin_7 [pin 7] - Pin_8 [pin 8] ### U1 — [MPR121QR2](https://www.flux.ai/jecstronic/mpr121qr2~65y.md) - Datasheet URL: https://www.nxp.com/docs/en/data-sheet/MPR121.pdf - License: https://creativecommons.org/licenses/by/4.0/ - Part Type: Integrated Circuit - Manufacturer Part Number: MPR121QR2 - Manufacturer Name: NXP USA Inc. **Pins:** - *IRQ [pin 1] - ADDR [pin 4] - ELE0 [pin 8] - ELE1 [pin 9] - ELE10 [pin 18] - ELE11 [pin 19] - ELE2 [pin 10] - ELE3 [pin 11] - ELE4 [pin 12] - ELE5 [pin 13] - ELE6 [pin 14] - ELE7 [pin 15] - ELE8 [pin 16] - ELE9 [pin 17] - HTAB [pin HTAB] - REXT [pin 7] - SCL [pin 2] - SDA [pin 3] - VDD [pin 20] - VREG [pin 5] - VSS [pin 6] ### U2 — [MPR121QR2](https://www.flux.ai/vasy_skral/mpr121qr2~xnn.md) - Manufacturer Part Number: MPR121QR2 - Part Type: Integrated Circuit - Datasheet URL: https://resurgentsemi.com/wp-content/uploads/2018/09/MPR121_rev5-Resurgent.pdf?d453f8&d453f8 - Manufacturer Name: NXP USA Inc. **Pins:** - ~IRQ [pin 1] - ADDR [pin 4] - ELE0 [pin 8] - ELE1 [pin 9] - ELE2 [pin 10] - ELE3 [pin 11] - LED0/ELE4 [pin 12] - LED1/ELE5 [pin 13] - LED2/ELE6 [pin 14] - LED3/ELE7 [pin 15] - LED4/ELE8 [pin 16] - LED5/ELE9 [pin 17] - LED6/ELE10 [pin 18] - LED7/ELE11 [pin 19] - REXT [pin 7] - SCL [pin 2] - SDA [pin 3] - VDD [pin 20] - VREG [pin 5] - VSS [pin 6] *The full schematic, PCB layout, bill of materials, and interactive design are available at [https://www.flux.ai/jaztin/arduino-uno-r3-shield-template~8q](https://www.flux.ai/jaztin/arduino-uno-r3-shield-template~8q).* --- *Generated from [https://www.flux.ai/jaztin/arduino-uno-r3-shield-template~8q](https://www.flux.ai/jaztin/arduino-uno-r3-shield-template~8q)*
