STeMCell VS crkbd

I ordered a pre-assembled STeMCell MCU. The dfu bootloader works, and I was able to flash the uf2 bootloader onto there, but i'm not sure how to put it into uf2 bootloader mode. When I power the MCU on while holding the BOOT0 button down, it goes back into dfu mode. Am I missing something?

in the meantime, we've been using stemcell controllers which don't have the same issue

And I do agree that ESD issues are often overblown, but since I gotten my hand on some STMCELL back when pro micros were hard to get , I had to think hard about esd protection as "This design does not have any fuse, esd protection or reverse voltage protection." https://github.com/megamind4089/STeMCell

stemcell, but you need to build it yourself.

Your promicro is not enough program memory(32kb) to use some animations, let's use another controller which have more program memory like stemcellhttps://github.com/megamind4089/STeMCell

The blackpill is not, but the bonsai c4 is, alongside the stemcell, if you're JLCPCB-wise

There are a few controllers that have the additional holes (puchi-c, goldfish, comet etc) not just the elite-c. StemCell is probably one of the more open ones and you can get them assembled at jlc I believe? https://github.com/megamind4089/STeMCell

I am trying to make a driver board for a trackpoint module. I have been following the instructions in the GitHub repository (https://github.com/manna-harbour/crkbd/tree/master/trackpoint) and found some helpful pictures (https://photos.google.com/share/AF1QipN-g61hYbBhwOErVaDARWP4fk5UqttkEkYN1Qzg_oO31v05qlJ-Y73XoyO_E6Bccw?key=RU5qcXplN3dXV1BnME42QnlFS0RwRlVaODQ1Z3hB) and blog post (https://rfong.github.io/rflog/2021/10/26/r61-trackpoint-pt2/) as well.

Ever since the illustrious /u/manna_harbour started sharing corne builds with integrated trackpoints, I'd been on the lookout for a way to get an integrated pointing device, but with my limited (or non-existent) hardware skills, it always seemed out of reach. Enter /u/sadekbaroudi and his faux fox keyboard (ffkb). For the first time, I found a kit which looked like it could bring integrated pointing to the masses with the cirque touchpad, and my resolve was finally broken. I caved and made my first purchase in two years. The fingerpunch discord community has proven to be an awesome and helpful place, as they've provided endless support with tweaking the cirque and debugging any firmware issues that have arisen (which have honestly been pretty limited for me).

You could do it like this: crkbd hotswap trackpoint. ThinkPad keyboard modules can be found on AliExpress for around USD10, but if you have to find the right model if you want to disassemble the trackpoint module to fit completely in that space.

Excellent, glad it helped! If you do want to add a trackpoint to complete the ThinkPad look, you can do it like this. For lowpro you can rearrange the components a bit to reduce the height.

I only succeeded thanks to /u/manna_harbour and his [guide](https://github.com/manna-harbour/crkbd/blob/master/trackpoint/readme.org) for corne.
