TTL to RS485 Module for Microcontroller Development RS-485 Communication

TTL to RS485 Module for Microcontroller Development RS-485 Communication

The on-board MAX485 chip is a low-power, swing-rate-limited transceiver for RS-485 communication, and the on-board connects to a 5.08(mm) pitch 2P terminal block, which is convenient for RS-485 communication wiring. All pins of the chip have been pinned out and can be operated by the microcontroller control
