I've made an PCB with an NRF24l01 (and some other stuff). But the NRF24l01 doesn't really work. I've tested the code (an HowToMechatronics example) with an Arduino nano connecting to an Arduino UNO and that worked fine but Arduino Leonardo (Atmega32u4) to Arduino UNO doesn't work for some reason. he…

NRF24L01 doesnt work with Arduino leonardo

The 3.3 volt supply is generated by the on-board regulator for the Leonardo, the spec states a Maximum current draw of 50 mA.

Anything else connected there?
