Tiny Tapeout chip demo board wiring to a Raspberry Pi

This page lists the two links between a Tiny Tapeout chip demo board and its Raspberry Pi: USB and the PMOD HAT ribbon. What the board is, is on The Tiny Tapeout chip demo boards. It holds no per-signal table of the ribbon.

The USB link

Item names a property of the link; Value is what the Raspberry Pi sees.

Item	Value
Carries	the controller’s USB CDC serial console, the MicroPython REPL
USB name	“MicroPython Board in FS mode”
VID:PID	2e8a:0005
Device	/dev/serial/by-id/usb-MicroPython_Board_in_FS_mode_<serial>-if00
udev symlink	/dev/ttboard to /dev/ttyACM0
Owner of the port	the fpgas-tt daemon, which republishes it as a WebSocket on port 8765
Liveness	https://tinytapeout.fpgas.online/board/<slug>/status.json, the daemon’s /health plus reachable

The daemon’s endpoints are on Serial port ownership on a Tiny Tapeout FPGA demo board. The steps to stop and start it are in How to free a Tiny Tapeout board’s serial port from fpgas-tt.

The PMOD HAT ribbon

A Digilent Pmod HAT ribbon brings the demo board’s PMOD connectors onto the Raspberry Pi’s GPIO header. The adapter is the Raspberry Pi PMOD HAT; the connectors are on Tiny Tapeout PMOD layouts. The cabling the wiring test expects is under The wiring test.
