2.1 RS485 & RS232 & GPIO Functions
No.14
- Serial Port Introduction
For serial port usage, refer to: https://www.cnblogs.com/lizhuming/p/14044396.html
- GPIO Introduction
GPIO Input The two GPIO input channels adopt full isolation design, supporting normal operation with input voltage ranging from 3.3V to 12V. Logic of IN1/IN2:
- When the switch is set to H: The device receives high level for input high, and low level for input low.
- When the switch is set to L: The device receives low level for input high, and high level for input low.
GPIO Output
The two GPIO output channels are isolated by MOSFET with open-drain design. They support control levels from 3.3V to 24V, with a maximum sink current of 100mA.

RS485 — ttyS5RS232-1 — ttyS7RS232-2 — ttyS3IN1 — GPIO3_D0IN2 — GPIO3_D4OUT1 — GPIO4_B0OUT2 — GPIO4_B2External pull-up resistors are required for OUT1/OUT2 to work properly.The output follows positive logic: OUT1 outputs high when GPIO4_B0 is set high, and outputs low when GPIO4_B0 is set low.
