Module with 2 relays and 4 IO pins (with analog input function) supporting communication via USB. It can control devices with a current of up to 2 A. The USB interface allows the user to easily connect the module to any devices with Windows, Linux, Mac or embedded computers such as RPi. It comes with built-in software that supports simple commands to control the relays and read their status. The board appears as a serial port when connected to a computer and can be operated by serial terminal applications such as HyperTerminal or Putty. Due to the fact that it uses 5V relays, it does not require any additional power supply (only via the USB port). Perfect for automation systems that require the control of multiple devices. Full documentation is available on the product page.
