lamaPLC: TTL to RS485 Module

The onboard MAX485 chip is a low-power, slew rate-limited transceiver for RS-485 communication. It is connected to 5.08 mm pitch 2P binding posts, which makes RS-485 wiring convenient. All the chip's pins are exposed and can be controlled and operated by the microcontroller. It operates on a single 5V power supply with a rated current of 300μA.
