M5Stamp UART-RS485 module - M5Stack S001

The M5Stamp UART-RS485 module from M5Stack is an extension of the Unit type in the form of an extension board for RS485 communication, which converts the TTL level of 3.3 V of the MCU serial port into a differential signal compliant with the RS485 standard. The small size of the module allows it to be integrated with various devices in order to extend them with an RS485 communication interface.
