PCBs for APRL electrical
The projects here rely on APRLLIBS and KICADUSERTEMPLATEDIR being set. You can do this by:
1. Going to Preferences > Configure Paths... 2. Setting APRLLIBS to wherever you cloned this repo + /kicadlibs. 3. Setting KICADUSERTEMPLATEDIR to whatever you set in (2) + /templates
The ALI itself can continue to be used for years to come and this reworking of the electronics will not impact it at all. This is going to be its own separate electrical box altogether. The ALI has the following additional limitations, too: 1. Limited I/O 2. Bonded grounds between +24/12/5V power supplies 3. Unknown…

Valvedrivers: common questions
What microcontroller does the Valvedrivers use?
The Valvedrivers is built around the STM32H563RIV6, from the STM32 family.
How big is the Valvedrivers PCB?
The Valvedrivers measures 85 × 76 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Valvedrivers?
148 components, from 37 distinct parts. The full bill of materials is listed on this page.
Where can I download the Valvedrivers design files?
From the npgo22/APRL-Electrical repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Valvedrivers design in my own project?
The repository has no license, so all rights stay with npgo22. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Valvedrivers without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
