I posted a few pictures of my internal Pico PSU card for the IBM PCir the other day, I thought I'd show y'all some updates I've done for Rev B
The most obvious thing I did was create a cutout for nstallation and wire pass through so the Pico can lay flat, qet air, and blend into the board. I also didn't like that in other integrations of the PicoPSU the power switch was wired to the board and not directlv to the PSU eaving the Pico on 24/7 lowering the life of the board and having a small chance of creating other issues. So, I fully integrated the PSU and created a hard shut off wiring the pico directly into the board. I made a few other cosmetic changes anc fixed small bugs I noticed with the first run. The last thing I did was add a 2x6 pin output for power. I want to use this to transfer power from this board to other upgrades for the PCir im working on reducing the amount of cords and nesting the future boards directly to the VoltBus freeing up space and creating an elegant solution to an awkward lavout inside the PCJr
The last picture was REV A for fitment, function, and further testing. Functionality it works flawlessly so far and has handled sidecars. I'm currently working on routing power from a JrCaptain that usually has outside power to see how it handles the load.
I really want to know what vall think before 1 order a few of these and keep testing. Any feedback or suggestions would be great!
