Raspberry Pi RFID/NFC reader with screen

Overview

Raspberry Pi: Both version B and zero are available.

Screen: Purchase any Raspberry Pi 3.5-inch screen kit from Taobao.

RF/NFC module: Any serial port NFC module, such as PN532, or the ID/IC universal card reader module available in many places on Taobao.

During the test, install the pin header and header on the Raspberry Pi pin header, so that the top of the screen can be superimposed and the bottom of the screen can be connected to the Raspberry Pi. If you need to make it more compact, you can remove the screen rows and weld them directly. Power is taken from the Raspberry Pi's USB.

Three-layer structure, five pieces are prototyped at a time, and one piece can be placed at the bottom as the bottom case; the PCB of the top cover is also attached inside.

I have used this set of boards to DIY a set of access control and a (fake) POS machine, which can be used with software development. As for why I used Raspberry Pi...because I didn’t learn any other microcontroller with good performance (show me)
