# RPi4-Water-Quality ## Description Template for Raspberry Pi 4 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 #Pi #RPi #Shield #template #project #project-template #raspberry ## Project Details -
