Just wanted to mention that Seeed Studio put an NRF52840 in the XIAO form factor:
Would be a good stopgap until we finally get an official MDBT50Q breakout with Espruino programmed in, if only it's in stock :P
ZigBee module ?
this could be a game changer.
how many ZigBee compatible MCUs are out there?
An Espruino build for this board would be really cool. The IMU is the same as in the Puck and there's also a flash chip!!
As a Bangle.js 2 owner, I'm also very intrigued by the concept of having a file system on the SPI flash that can be accessed via BLE through the web IDE. This would enable really cool data logging options on the simpler, cheaper espruino boards.
Is this hard to implement? You'd require some kind of simplified, stripped-down build of Bangle.js 2 or is there a simpler way?
In this context I also thought about spinning my own Puck PCB with the MDBT42 and for example a GD25Q16 flash chip, since I have some laying around here.
The Storage module on external flash is independent of Bangle.js, so actually it should be pretty easy to get it running on the XIAO. The IMU isn't independent of Puck.js though, so I guess you'd have to make a modified Puck.js build for it - even so, it wouldn't be a huge deal
Don't worry about formatting, just type in the text and we'll take care of making sense of it. We will auto-convert links, and if you put asterisks around words we will make them bold.
