Develop schematic, and PCB layout for an FTDI-based serial debugger

Posted 2 weeks ago

Summary

I need a complete KiCad design (schematic + layout + Gerbers + BOM) for a USB-powered multi-protocol interface board built around the FTDI FT2232H. The board is a debugging/hardware-hacking tool exposing UART, JTAG, SPI, and SWD from a single USB-C connection. Key requirements Main IC: FT2232HL (LQFP-64). The land pattern must be a merged footprint that also accepts the FT2232HQ (QFN-64), so either package can be populated depending on availability. The two share the same pinout. Plan for the QFN center thermal pad. Board shape: regular decagon (10 sides), approximately 2 inches in diameter. Connectors and headers: USB-C for data and power. Separate broken-out pin headers for UART, JTAG, SPI, and SWD, arranged around the perimeter (one protocol per edge area). A logic analyzer header positioned on the edge directly opposite the USB-C connector. Two or more 3.3V power pins near the center of the decagon, to power a target device if needed. SWD detail: include a switch that bridges the TDI and TDO pins through a 470 ohm resistor, to form the bidirectional SWDIO line for SWD mode. EEPROM: include an external 93LC56 (or compatible) EEPROM for FTDI configuration, to allow a unique serial number, custom VID/PID, and product string. Power: 3.3V regulation from USB 5V, sized for the FT2232H plus a reasonable target load. Specify the regulator and current budget. Deliverables KiCad project files (schematic + PCB), version 8 or 9. Gerbers and drill files ready for fab. Pick-and-place (centroid) file. BOM with manufacturer part numbers. Assembly drawing or placement notes. Sourcing All components must be verified in stock at JLCPCB for an order quantity of 100 units. Prefer JLC basic parts where possible to reduce assembly cost; note any extended parts. Flag any part with marginal stock and suggest an alternate.
