Overview
Mega nrf24 usb is an open-source printed circuit board by douglaslyon, from the douglaslyon/pentester repository on GitHub, published under the GPL-3.0 licence. It is a 2-layer board of 14.2 × 36 mm with 14 parts on 39 nets, routed with 211 tracks and 28 vias.
It is built around the ATMEGA32U4-MUR. Its parts include 3 capacitors, 3 connectors, 2 resistors, 2 ICs and 1 diode. It belongs with the AVR (ATmega, ATtiny) boards of this library.

Library Info
Code can fail when there is a contention issues between multiple similarly named libraries or the wrong one is present. Make sure you have installed (from the library manager) the latest TMRh20 RF24 library installed. DO NOT use the maniac bug version. The TMRh20 RF24 Library has printf in it as well.
PENTEST_NRF is a newly developed library for easy reliable rf communication using the rfmicro and nrf24. Using this library, you still create the RF24 object in your own code and thus retain all of it's members while being given supplemental functions and reliable transmission abstraction aimed towards penetration testing. PENTEST_KBD is the new library for penetration testing keyboard based functions such as opening a command prompt and executing other commands
Various Device Pinouts
rfMicro - CE:8 CSN:7 rfNano - CE:10 CSN:9 nrfShields - CE:9 CSN:10
Working Examples
rfCMDuserInput
Reciever must be an rfMicro. Make sure to check CE and CSN pins. Enter commands from the serial monitor of the host computer and have them sent over RF transmission and typed into the host's command prompt or terminal. Working with windows and mac, bug fix needed in linux.
Reliability Test
Does not use keyboard functions, use to test reliability of transmission methods. I have sent 200+ transmissions without a single failure. it will print the failure count every 50 transmissions.
Malduino Compatibility
The malduino contains and SD card and a button that are not present on the rfMicro. Malduino scripts relying heavily on the sd card require further adjustment however most simply need to have the use of the button (that starts a script) taken out. This can easily be exchanged for a trigger command over the RF channel.
