What this shield can do?

  • Work with any Arduino Nano
  • Work from 15-30 AC/DC.
  • Have 4x220v sensor
  • Have 4x8A switch relay
  • Have 2x0-10V output
  • Have RS-485
  • Have one pulled-up pin for 1-wire
  • 2 arduino/1 uniport out

Pin-out for auduio

  • D2,D3,D4 - TX,RX and RE/DE of 485
  • D5,D6 - PWM output for 0-10V
  • D7-D10 - control for switch relay 1-4
  • A4 - pulled up output for 1-Wire
  • A0-A3 - sensors input
  • D11,D12 - uniport RX/TX or direct out
