Build Log: Reviung41lp

My second fully wireless build! I have been using this now as my daily driver since I built it and it’s a strong candidate for my long term travel ambitions.

The BOM

The Build

Given this is a wireless-only board for me, there are no frills, no OLED displays, no LEDs, nothing of the sort, just a controller, a bunch of diodes, and a bunch of hotswap sockets. So it went really quickly.

One really great thing about this board is it has some extra nice bits for battery-powered usage. On-board is an inline power switch to disconnect the battery, and 2 pads for soldering the battery leads to. The battery fits nicely underneath the nice!nano, though if I were to make this myself I would set it up such that the nice!nano is flipped so it can sit a little lower on the board. I would also have made the battery lead pads be through hole rather than surface mount as they probably would have been easier to solder.

For firmware, I’m using the awesome ZMK. Cyril was kind enough to create a shield in zmk for this so adding my keymap was as simple as copying his overlay file into my repo and setting up my keymap. Then, I let the github actions take over, build my firmware, and copy it to my board. Easy peasy. The way the nice!nano takes firmware updates is you double click the reset button and it exposes itself to the host OS as a USB drive, then you drag the firmware over. This doesn’t seem to work with iPadOS, however, so it’s not perfect, yet, but I’d like to see what I can do to help make that a reality, as that would allow me to update my firmware on the road without having access to a computer.

The Finished Product

This is still my daily driver and likely will be for the foresee able future. I am not the biggest fan of clicky switches, but the choc whites and the choc robins provide the tactility that I like that the browns don’t deliver. I’m looking forward to getting my hands on a similar PCB with chocv2 switch support and building that up. I also feel like I like mx spacing better, but I’ve been getting used to the choc spacing on this board, so who knows.
