Using VDD_PA on the nRF24L01/+ to power another microcontrollerhttps://devzone.nordicsemi.com/f/nordic-q-a/51039/using-vdd_pa-on-the-nrf24l01-to-power-another-microcontrollerHi everyone, I was looking to use the nRF24L01/+ along with a small microcontroller (e.g., ATtiny) and I wanted to reduce the BoM as much as possible. I was planning to use the ATtiny for simple processing where it should use less than ~1 mA of currenten-USTelligent Community 13Fri, 16 Aug 2019 09:14:44 GMTRE: Using VDD_PA on the nRF24L01/+ to power another microcontrollerhttps://devzone.nordicsemi.com/thread/204433?ContentTypeID=1Fri, 16 Aug 2019 09:14:44 GMT137ad170-7792-4731-bb38-c0d22fbe4515:e3b1647c-4a04-4486-ba70-85e66aeb3f7cSimonr<p>Hi Jay</p> <p>No, this won&#39;t be possible.VDD_PA can only be used as a signal to PA/LNA. It will only be high when the radio is in TX, an will not output anything when the nRF24L01 is in power saving mode, or any other mode than TX for that matter.</p> <p>Best regards,</p> <p>Simon</p><div style="clear:both;"></div>
