nRF24 Playset

The nRF24 Playset is a collection of software tools for wireless input devices like keyboards, mice, and presenters based on Nordic Semiconductor nRF24 transceivers, e.g. nRF24LE1 and nRF24LU1+.

All software tools support USB dongles with the nrf-research-firmware by the Bastille Threat Research Team (many thanks to @marcnewlin)

Requirements

nRF24LU1+ USB radio dongle with flashed nrf-research-firmware by the Bastille Threat Research Team, e. g.
- Bitcraze CrazyRadio PA USB dongle
- Logitech Unifying dongle (model C-U0007, Nordic Semiconductor based)
Python2
PyUSB
PyGame for GUI-based tools
