# 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:** shjnv66 - **Created:** 12/4/2024 - **Last Updated:** 1/28/2025 - **Visibility:** Public ## Key Components ### U1 — [Nodemcu-12E ESP8266](https://www.flux.ai/jharwinbarrozo/nodemcu-12e-esp8266.md) - Datasheet URL: https://components101.com/development-boards/nodemcu-esp8266-pinout-features-and-datasheet - Manufacturer Part Number: Nodemcu-12E ESP8266 - Part Type: Microcontroller **Pins:** - 3V3 [pin 11] - 3V3 [pin 25] - 3V3 [pin 16] - A0 [pin 1] - CMD GPIO11 [pin 7] - D0 GPIO16 [pin 30] - D1 GPIO5 SCL [pin 29] - D2 GPIO4 SDA [pin 28] - D3 GPIO0 [pin 27] - D4 GPIO2 [pin 26] - D5 GPIO14 [pin 23] - D6 GPIO12 [pin 22] - D7 GPIO13 [pin 21] - D8 GPIO15 [pin 20] - EN [pin 12] - GND [pin 17] - GND [pin 14] - GND [pin 10] - GND [pin 24] - RST [pin 13] - RSV1 [pin 2] - RSV2 [pin 3] - RX GPIO3 [pin 19] - SCLK GPIO6 [pin 9] - SD0 GPIO7 MISO [pin 8] - SD1 GPIO8 MOSI [pin 6] - SD2 GPIO10 [pin 4] - SD2 GPIO9 [pin 5] - TX GPIO1 [pin 18] - VIN [pin 15] ### U2 — [TB6612FNG,C,8,EL](https://www.flux.ai/adrian95/tb6612fngccc8cel.md) - Manufacturer Name: Toshiba Semiconductor and Storage - Part Type: Integrated Circuit - Datasheet URL: https://www.mouser.com/datasheet/2/408/TB6612FNG_datasheet_en_20141001-708260.pdf - Manufacturer Part Number: TB6612FNG,C,8,EL - License: https://creativecommons.org/licenses/by/4.0/ **Pins:** - AIN1 [pin 21] - AIN2 [pin 22] - AO1@1 [pin 1] - AO1@2 [pin 2] - AO2@1 [pin 5] - AO2@2 [pin 6] - BIN1 [pin 17] - BIN2 [pin 16] - BO1@1 [pin 11] - BO1@2 [pin 12] - BO2@1 [pin 7] - BO2@2 [pin 8] - GND [pin 18] - PGND1@1 [pin 3] - PGND1@2 [pin 4] - PGND2@1 [pin 9] - PGND2@2 [pin 10] - PWMA [pin 23] - PWMB [pin 15] - STBY [pin 19] - VCC [pin 20] - VM1 [pin 24] - VM2 [pin 13] - VM3 [pin 14] ### U3 — [BME280](https://www.flux.ai/vasy_skral/bme280.md) - Part Type: Integrated Circuit - Manufacturer Name: Bosch Sensortec - Symbol Style: Parametric - License: https://creativecommons.org/licenses/by/4.0/ - Datasheet URL: https://www.bosch-sensortec.com/media/boschsensortec/downloads/datasheets/bst-bme280-ds002.pdf - Manufacturer Part Number: BME280 **Pins:** - CSB [pin 2] - GND [pin 7] - GND [pin 1] - SCK [pin 4] - SDI [pin 3] - SDO [pin 5] - VDD [pin 8] - VDDIO [pin 6] *The full schematic, PCB layout, bill of materials, and interactive design are available at [https://www.flux.ai/shjnv66/arduino-uno-r3-shield-template](https://www.flux.ai/shjnv66/arduino-uno-r3-shield-template).* --- *Generated from [https://www.flux.ai/shjnv66/arduino-uno-r3-shield-template](https://www.flux.ai/shjnv66/arduino-uno-r3-shield-template)*
