Embedded debug
About the Embedded debug PCB
Embedded debug is an open source PCB design by stephendpmurphy, published on GitHub under the CC-BY-SA-4.0 license. It is a 2-layer board measuring 50.8 × 24.1 mm, with 21 components from 11 distinct parts.
Other key parts include the FT230XQ. By type, the board carries 7 resistors, 6 connectors, 4 diodes, 2 capacitors, 1 IC and 1 switch.
It belongs with the usb & debug tools designs in this gallery.
From the project
The embedded debug board can be used to provide access to Target MCU debug UART lines carried on unused traces of a 10pin SWD connector
This debug board allows two unused traces of a 10pin (1.27mm pitch) connector to be broken out and used for a UART RX & TX line from the target MCU. These UART lines can be used by the Target to send debug print statements through the programming connector, to the USB bridge, and then displayed on a PC terminal. This is useful since board space is no longer needed on the target for any sort of extra headers or test pads for debug data.
