README
pcbs/minsync/README.mdminsync
A minimal testbed for a RP2040-based board with an Si5351 as a clock source instead of the usual 12MHz crystal.
IO:
- Four clusters of six GPIO pins and 5V + GND power pins to allow easy chaining of the board.
- Headers for SWD flashing
- A bootsel button
- Testpoint for a gpout pin for debugging internal clocks

Questions
How big is the Minsync connect PCB?
It measures 17.4 × 14 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Minsync connect use?
2 parts. 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 Minsync connect KiCad files?
From the PietPtr/picotide repository on GitHub, at the commit this page was made from: the board is pcbs/minsync_connect/minsync_connect.kicad_pcb and its schematic pcbs/minsync/RP2040_minimal_r2.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Minsync connect design in my own project?
Its repository states no licence, so its author keeps all rights: ask PietPtr before reusing the design.
