README
v1 PCBs/README.mdV1 PCBs
V1 PCB and various files are now uploaded!
If you want to build your own lemonshark board, please use the V2 PCB (coming soon!). V1 currently has a few issues (various bodges and janky solutions) and is only uploaded for reference purposes.
The build guide uses a V1 PCB <- build guide coming soon this is just because i don't have a V2 PCB on hand, and probably won't for a while. However, if and when I do obtain a V2 PCB, i will create another build guide for V2.
UPDATE: V1.1 PCBs uploaded, these have replaced V1. This eliminates bodges, but is still limited to running choc V1 only and LEDs through a level shifter
