Current status:
Rev A0 (NOT RECOMMENDED FOR PRODUCTION, READ STATUS)
I've received and built this version and it works fine but i made the mistake of wiring up the GND and VBUS pins on the ESD chip incorrectly.
Thankfully those are the middle pins and simply desoldering and turning the chip around solves the problem.
Update: Finally had time to test the load sharing circuitry and i had the pinout of the mosfet setup incorrectly which requires bodge wires to fix.
If you are looking to get boards made from this revision you need to be aware of this but my recommendation would be to wait for the next one.
Rev B0
This should address all the issues in A0 while also adding some features that were not previously present such as:
- Leds for charge and bootloader status.
- Voltage divider for charge monitoring.
- SMD USB port so it can be mounted by JLC.
Boards have been ordered but not yet received so production is still not recommended.

Questions
How big is the Plonck PCB?
It measures 228.6 × 78.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Plonck use?
132 parts, built around the SRV05-4, 1N4148W, 19-217/BHC-ZL1M2RY/3T and KT-0603R. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Plonck KiCad files?
From the swampmonster/plonck repository on GitHub, at the commit this page was made from: the board is plonck.kicad_pcb and its schematic plonck.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Plonck design in my own project?
Its repository states no licence, so its author keeps all rights: ask swampmonster before reusing the design.
