🌟 What Is This? (From My Schematic PDF)
Custom FPGA development board designed from scratch in KiCad for Lattice MachXO2 LCMXO2-640HC-6MG132I (640 LUTs, 132-ball CSBGA).
Full breakout board, not simple LED:
- USB Mini-B (J1) for power + data with ESD protection USBLC6-2SC6 (U2)
- Dual LDO: 5V→3.3V TL1963A-33DCYR (U4) and 5V→1.2V LD1117S12CTR (U5) for core + I/O
- FT231XQ USB-UART bridge (U7) for serial
- JTAG header 1x10 (J2) for Lattice HW-USBN-2B programmer (10 flywires - White TCK, Orange TDI, Brown TDO, Purple TMS...)
- All 4 I/O Banks broken out: Bank0 Top (PT6A...), Bank1 Right (PR28... LVDS), Bank2/3 Left (PL2A...), Bank Bottom (PB4A...) + GND/NC
- Power LEDs D1 D2, User LEDs, Button SW1 for PROGRAMN
Why I made my own? To learn FPGA hardware - Power sequencing, decoupling, JTAG, I/O banks.

Questions
How big is the MACHXO2 test PCB?
It measures 65 × 48 mm and has 4 copper layers, 1.6 mm thick.
What parts does the MACHXO2 test use?
52 parts, built around the LCMXO2-640HC-6MG132I, FT231XQ-R, USBLC6-2SC6 and 1N5819HW. 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 MACHXO2 test KiCad files?
From the jay-waghmare/MachXO2-KiCad-Board repository on GitHub, at the commit this page was made from: the board is MACHXO2_test.kicad_pcb and its schematic MACHXO2_test.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the MACHXO2 test design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
