RS485 module which covert TTL to RS485 Logic levels for RS485 protocol Communication. It supports Industry-Standard RS485 protocols. Going from TTL to RS485 is made simple by this prototyping friendly module. On one side of the board are the TTL IOs, and on the other are the RS485. At the core is a MAX485 which is powered by 5V.
