Wow, we did not expect the level of interest you all have had in the !

More info:
- Cost will be approximately 25USD
- Charging dock included in price
- Built-in heartbeat monitor
- Case built of Zinc alloy and plastic
- Battery life measured in days
- Sorry, can't run Linux itself. SoC is nRF52832, which uses a Cortex-M4 core. That's why we need FreeRTOS :)


It is not a relatively simple matter of porting it. The Cortex M cores are microcontrollers, and are much simpler than the Cortex A series.

In particular, they do not have a memory management unit (MMU), which is necessary for normal Linux.

There is a variant of Linux (uCLinux) which technically works on the Cortex M cores, but the chip we are using likely does not have enough RAM, and uCLinux seems to be a dead project as far as I can tell.

@PINE64 @blendergeek Wasn't ucLinux merged with mainline? I do agree, though, that running Linux seems a bit wasteful for a microcontroller based device like this.

@neil @blendergeek

You're not wrong, but the Cortex M support was not merged to mainline. Also most of the chip support that was brought over was ended in 4.17.
