Not sure what you are asking about - to me it looks like that's what I'm doing on the video :)
Unfortunately I have no idea what you are using there - nrf24 is pretty standard Arduino module (nrf24L01 is probably the most popular one) and any of its variants should work without any changes in the code
Thanks :) It was a 2-cell LiPo with DCDC stepdown, resulting in 5V
