EFM32QUAD - EFM Processor with Dual RS232 Interfaces and Four DF11 10 pin Connector Sites

  • 3595

We currently have 2 in stock.

Description:

This module contains an EFM32WG840 Gecko low power microcontroller and dual RS232 Interfaces. Up to four DF11 I/O modules can be plugged on with no soldering allowing multiple sensors and/or controllers to be used. It can be programmed with the Arduino IDE. It works with the easy to use Arduino IDE programming environment. It is small but powerful and is a great learning tool. It can be used in industrial strength products. It can be used with the openHAB home automation system for sensors that can be connected to the server via USB.
