There's no AD/DA function on the Raspberry Pi GPIO interface, this may trouble you in the Pi development. However, it won't be a problem anymore. The High-Precision AD/DA Board allows you to add high-precision AD/DA functions to the Raspberry Pi.
Features
Standard Raspberry Pi 40PIN GPIO extension header, supports Raspberry Pi series boards, Jetson Nano
Received the product in very good packaging, also the way it was inside it seems they test the display before shipping which is a great thing ensuring defective piece doesn't get delivered! Very fast delivery. Highly recommended!
