Description
Product Instruction:
The on-board MAX485 chip is a low-power, slew rate-limited transceiver for RS-485 communication. The onboard is connected to 5.08(mm) pitch 2P binding posts, which is convenient for RS-485 communication wiring. All the pins of the chip have been drawn out and can be controlled and operated by the microcontroller.It works at a single 5V power supply and the rated current is 300uA.
Pin definition:
RO: Receiver output
RE: Receiver output enable
DE: Driver output enable
DI: Drive input
VCC: 5V power supply
A: The non-inverting input of the receiver and the non-inverting output of the driver
B: Receiver inverting input and driver inverting output
GND: Ground
