PCB Design – E-Paper Display Driver Board (UC8279 / ESP32-C6)

I'm building a wall-mounted e-paper calendar display. I need a PCB designed for JLCPCB SMT assembly a first attempt was made but has many errors and needs to be done correctly by a qualified electronics engineer. The display: Guangdong SID Technology SE0750NW31-MNG-A0 — 7.5" black/white EPD, 800×480, UC8279 controller. Datasheet attached. The reference circuit on page 17 is the ground truth for this design. The microcontroller: Seeed XIAO ESP32-C6 — must be socketed (2× 7-pin 2.54mm female headers), not soldered directly to the board. What the board needs to do: Accept the XIAO on socket headers Connect to the display via a 24-pin 0.5mm pitch bottom-contact ZIF FPC connector Implement the boost converter circuit from page 17 of the datasheet (VGH/VGL generation using L1 22µH, Q1 MOSFET, D1/D2/D3 diodes, supporting caps and resistors) Route SPI signals (MOSI, CLK, CS, DC, RST, BUSY) from the XIAO to the FPC All passive components 0402 where possible Constraints: All components must be available through JLCPCB's SMT parts library (LCSC part numbers in BOM) Standard JLCPCB 2-layer PCB process Max board size approximately 60×50mm — smaller is fine M2.5 mounting holes in corners preferred Output: KiCad project files preferred, or Gerbers + BOM + CPL as minimum What I'll provide: SE0750NW31-MNG-A0 datasheet (including page 17 reference circuit) Existing KiCad files, python design script, BOM and CPL files from first attempt (for reference only — do not assume these are correct) Please only bid if you have experience with EPD display driver circuits or similar boost/charge pump power topologies. Fixed price preferred.
