Description: This is a nicely packaged key FOB that contains a Nordic nRF24L01+ radio and a ATtiny24 for control. Press any one of 5 buttons and the ATtiny24 will wake up, transmit the buttons being pressed, a 16-bit integer value of the total button presses since last battery replacement, and then return to low-power sleep. The simple to replace 20mm coin cell will last for over 3 years. This unit comes fully assembled with battery and enclosure. FOB transmission range is quite nice at over 100ft. Use this FOB to communicate with any nRF24L01+ radio module for your next remote control project.
