I am wondering if it is possible to power an nrf24l01 from one of Attiny85's analog output pins. I am thinking of the following setup for power:
CR2032 (3v) ---------> Attiny85(VCC)------>Attiny85(analog output pin)---> nrf24l01(VCC)
Hence when attiny is in deep sleep mode, nrf24l01 is also switched off. This should considerably reduce the power consumption.
Theoretically speaking, Attiny's analog output pin can output around 40mA and nrf24l01's power consumption is 11.3mA transmitting, 13.5 receiving.
Thank you for your comments.
