I made a 16 button RF remote control with a Promini and 434 MHz transmitter.On a button press, the promini wakes up, sends the key pressed, goes back to sleep.Receiver(s) must be awake all the time to listen for messages.Powered from 1000mAH LiPo battery.Blank spot was for MAX1811 battery charger chip.
