Low power mode?

[Barada Mishra]

Hi All,

I am new to nrf51822. I need a much less powerful CPU than the 16MHz CPU, is there a way to slow down the CPU to save power?

Thanks

No, the MCU clock speed is fixed at 16MHz. To save power, it's better to do the task and put the MCU to sleep until it's time to serve the task again.
