Device

Product description

This is a feature packed I/o board with an ESP32-S3-WROOM-1U-N16R8.

It has

  • Powered by ESP32-S3 with dual-core Xtensa LX7 CPU up to 240 MHz
  • Integrated 2.4 GHz Wi-Fi + Bluetooth LE with external antenna
  • Ethernet port than can provide PoE power
  • Isolated RS485 interface for Modbus sensors/modules
  • Isolated CANbus interface
  • 8 optocoupler isolated inputs
  • 8 optocoupler isolated outputs
  • External i2c header
  • GPIO header for expansion (e.g. RS232, sensors)
  • USB-C for power, firmware upload, and debugging. Can provide power to other devices with a jumper
  • 7–36V wide-range input via screw terminal for industrial use
  • Status indicators: buzzer, RGB LED, power, RS485 TX/RX
  • ABS rail-mount enclosure for safe, easy installation

The board can be powered either via 7-36DC or via 5VDC (USB-C). Outputs provide current sinking up to 500ma
