Brief description:

This module contains relevant screw holes, which are positioned according to the fixing screw holes of the fox second-generation aluminum alloy shell. The main functions are OLED display, PCF8574 key matrix, AT24 storage and DS1307 clock. Through IIC communication, the address can be changed through the relevant resistor. The attached function IR module is used to receive infrared signals, and the CH330 chip is used to connect to the TTL debugging interface of R2S. The type-c interface also contains the protection circuit of R2S itself, so the output interface power cord can be directly connected to the 5V power supply port reserved by R2S.
