I’ve never really been happy about power for boards like this.
Is there something much much lighter that can run off a CR2032? For some applications all one really needs is zigbee for access, or something like that.
Or the alternative is a Pi-like with POE. Last time I did that with a Pi it involved a relatively expensive “hat” which felt suboptimal.

- snemvalts 5y agoNothing on ARM (and with linux) probably that can run off a button cell. Down to arduino etc microcontroller level.
- ahepp 5y agoI am not aware of a linux board that can do this. It'd be pretty sick though, I'd love to be proven wrong. It seems to me that a microcontroller with an RTOS might be more up this alley (perhaps the esp8266/esp32 platform, but I'm no expert).
