About the Goodfet PCB

Goodfet is an open source PCB design by travisgoodspeed, published on GitHub. It is a 4-layer board measuring 84 × 82 mm, with 234 components from 53 distinct parts.

Other key parts include the UMN1N, DG408, GSG-LM339, UMP1N and MC4558. By type, the board carries 122 resistors, 68 capacitors, 31 ICs, 6 connectors, 3 diodes and 2 inductors.

From the project

An embedded bus adapter for various microcontrollers and radios.

TOAD: Totally Over-engineered Adapter/Detector

designed with KiCad: http://www.kicad-pcb.org

This is an experimental add-on module for the gflpc1343. Firmware for this board does not yet exist.

TOAD supports UART communication with configurable pinout and configurable voltages including both TTL and RS-232 levels. It also has some interesting probing and sniffing capabilities.
