What’s on Board:

Waveshare 2-Channel Isolated RS485 Expansion HAT for Raspberry Pi

  1. SC16IS752 UART expansion chip
  2. ADUM1412 digital isolator
  3. PC817 optocoupler
  4. SP3485 RS485 transceiver
  5. B0505LS power supply isolation module
  6. RT9193-33 power chip
  7. SMAJ12CA transient suppress diode array
  8. Auto-recovery fuse
  9. Status indicator
    PWR: power indicator
    RXD/TXD: UART transceiving indicator
  10. Raspberry Pi GPIO connector: for connecting Raspberry Pi
  11. RS485 terminal
  12. MCU control header: for connecting host control boards like Arduino
  13. 120Ω terminal resistor switch
  14. Interrupt pin switch
  15. Operating mode selection
    Half-auto: A=0, B=1
    Full-auto: A=1, B=0

It is easy to control the 2-channel RS485 for auto-transceiving via the SPI interface. Due to its fast communication, stability, reliability, and safety, it is an ideal choice for fields like industrial automation.
