PCB for the Wireless Gateway, as described in Elektor Magazine, May 2014 edition.
This board carries a small low power radio module (HopeRFRFM12B) along with an ATmega326 microcontroller and a serial interface. Pre-programmed firmware allows the board to be used as a simple gateway for strings of characters between the serial interface and the ether.
