About the Debugotron - SWD Sample Target PCB

Debugotron - SWD Sample Target is an open source STM32 PCB design by alvarop, published on GitHub under the BSD-3-Clause license. It is a 2-layer board measuring 39.7 × 14 mm, with 30 components from 15 distinct parts.

Its main chip is the STM32L412C8T6, from the STM32 family. Other key parts include the SN74AHC1G08DBVRG4, MIC5504-3.3YM5-TR, TMUX1511PWR and LM358QT. By type, the board carries 11 resistors, 9 capacitors, 5 ICs, 2 switches, 2 diodes and 1 connector.

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

Have you ever wanted to debug your device over USB-C? Sometimes there's not enough room for a JTAG/SWD connector, or even TAGConnect pads! The USB-C specification has a Debug Accessory Mode feature that allows for this. I have a Twitter thread with additional details. Here's an unrolled version for easier reading.
