Hello, is it possible to use nRF24LU1 with Li-Po 3v7 battery?
As far as i remember, maximum supply voltage for nrf24lu1 is 3.6V, so that would be a no, you cann't connect 3.7V battery to it directly. But you should check the datasheet to be sure.
The nRF24LU1 datasheet says you can power it through VDD between 3 and 3.6 volts
A fresh lipo will be closer to 4v so ideally you need to LDO voltage regulator to limit the volts.
Pick an LDO with the smallest voltage drop while providing enough current for your circuit.
