About the Tigard PCB

Tigard is an open source PCB design by mukkasrikanth, published on GitHub. It is a board, with 89 components from 37 distinct parts.

Other key parts include the AP7365-18, AP7365-33, FT2232HQ, 93LC46BT-I/OT and SN74LVC8T245. By type, the board carries 31 resistors, 26 capacitors, 7 connectors, 6 ICs, 5 diodes and 3 inductors.

It belongs with the usb & debug tools designs in this gallery.

From the project

A Python script that reconstructs the Tigard v1.1 hardware hacking tool's PCB circuit using SKiDL, producing a KiCad-compatible .net netlist file entirely from code — no schematic editor required.
