Template for Raspberry Pi 5 Model Shield. Include an official pinout so you will always know Raspberry Pi names, the alternative roles of pins, which one is SDA, or SCL, etc. On PCB you can find the 3D model of the Raspberry Pi itself along with the board outline on the silkscreen. #RaspberryPi #Raspberry #RaspberryPi5 #raspberry #Pi #RPi #Shield #template #project #project-template

This is the multipurpose PCB that works with Arduino Nano, a way that you can run 2 Stepper motors, 2 DC motors, 2 Servo motors at the same time and this is not it you can even connect BT module, rotary encoder, I2C device, potentiometer at same time. This PCB is very much helpful in building any project and no need to worry about messy wire connections.
