Im working my way through a lot of datasheets to find the lowest power solution for an LWMesh compatible battery powered device. Hope maybe has done some research like this before.
There are of course the ATSAMR21E18 and the Mega version ATMEGA256RFR2 microcontroller with built-in RF with quite a low power deep-sleep mode. But when I look at the RF transceiver AT86RF231, this chip is more low power. But needs a microcontroller.
So what is the best option out there.
We want to built a cheap(mass production) battery powered remote that is of course very low power. The microcontroller needs to wake up at button-press so it needs some external interrupts as well.
Someone any ideas?
