The final #eReaderCarrierBoard and #eReaderHat update. The project can play audio now via Bluetooth as shown in this video.

New #eReaderCarrierBoard & #eReaderHat #UI features. Now you can add a #calibreserver directly from the #GUI. Not the prettiest design, but its functional. #selfhosting you're own book server is slowly becoming more practical.

Quick video showing new features for the #eReaderHat and #eReaderCarrierBoard. This clip showcases the #raspberrypi #computemodule4 but there's another #PCB in the HAT form factor. The #hardware now supports a touchscreen, backlight, as well as a lipo battery. Pretty happy with this revision so will be working on #firmware in the near future.
Will post documentation in the thread below.

I just realized I never posted the #pcb layouts I did for the #eReaderHat and #eReaderCarrierBoard. Well the design is back from fab and now the project has a touchscreen and backlight. Already noticed some changes I want to make, but I'll be working on #firmware to implement all the new #hardware into the GUI. I'll post a video that shows the new features soon enough.
A #eReaderHat and #eReaderCarrierBoard update. Despite the silence, I've been working on a new display for the project. Still have a lot of work to do but all the hardware, #epaper , touchscreen, and backlight, are working but I still have to integrate them into the #firmware and design a new #pcb for the new #hardware .

Never posted about the new touchscreen assembly for the #eReaderHat and the #eReaderCarrierboard. I've ported firmware to run on a #raspberrypi but still need to integrate LVGL. Making progress though.
🚨new hardware alert🚨
The touchscreen #epaper assemblies shipped much faster than i expected. The driving IC is different than the display I'm currently using so I have a lot of firmware to write while the boards with lipo charging are made.

Finally added lipo charging capabilities to the #eReaderCarrierBoard . Note the JST connector in the top right and the USB micro connector. Thanks to @PCBWay for sponsoring this project!

Working on portable power for the #eReaderHat and #eReaderCarrierBoard . Found a perfectly sized lipo battery and have a series of breakout boards that implement charging, fuel gauge, and consistent 5V output. Not the sexiest feature but the work needs to be down.
