Teensy_41_Debug_PCB

Teensy 4.1 Debug PCB

This modification adds the ability to connect to a Teensy 4.1 device over JTAG with a Segger J-Link Debug Probe.

This PCB is only for the newest Teensy 4.1 with the GD32 bootloader chip.

The previous method has been depreciated, keeping the bootloader chip in place has proven to be much easier.

Questions

How big is the Teensy Debug PCB?

It measures 8.7 × 14.5 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Teensy Debug use?

7 parts, built around the TEENSY 4.1. 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 Teensy Debug KiCad files?

From the SpenceV1/Teensy_41_Debug_PCB repository on GitHub, at the commit this page was made from: the board is Teensy Debug.kicad_pcb and its schematic Teensy Debug.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Teensy Debug design in my own project?

Its repository states no licence, so its author keeps all rights: ask SpenceV1 before reusing the design.
