Overview

SWD UART CTX-10 is an open-source printed circuit board by TL-Embedded, from the TL-Embedded/SWD-UART-CTX-10 repository on GitHub. It is a 2-layer board of 31.4 × 30 mm with 15 parts on 21 nets, routed with 63 tracks and 12 vias.

It is built around the SFH11-PBPC-D10-RA-BK. Its parts include 4 connectors and 2 resistors. It belongs with the interfaces and adapters boards of this library.

SWD-UART-CTX-10

This is an adaptor for the 10 pin tag-connect cables.

Output:

  • TC2050 or EC10 ribbon

Input:

  • UART via standard FTDI header
  • SWD via standard 20 pin ARM header
  • Auxilary voltage input

This is compatible with the Tag-Connect TC2050-ARM2010 ARM 20-pin to TC2050 Adapter in SWD mode.

Target pinout

On the target, the TC2050 or EC10 should have the following assignment.

Pin#Function
1VCC_Target
2SWDIO
3GND
4SWCLK
5VCC_Aux
6SWO
7TX (to target)
8Detect
9RX (from target)
10Reset

Detect

This pin is tied to ground on the adaptor - and can be used by the target to sense the presence of the adaptor.

VCC_Aux

This is tied to the V+ pin. This is an optional input for providing arbitrary power to the target.

TX & RX

The Tx and Rx are described with respect to the host, not the target.

Questions

How big is the SWD UART CTX-10 PCB?

It measures 31.4 × 30 mm and has 2 copper layers, 1.6 mm thick.

What parts does the SWD UART CTX-10 use?

15 parts, built around the SFH11-PBPC-D10-RA-BK. 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 SWD UART CTX-10 KiCad files?

From the TL-Embedded/SWD-UART-CTX-10 repository on GitHub, at the commit this page was made from: the board is SWD-UART-CTX-10.kicad_pcb and its schematic SWD-UART-CTX-10.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the SWD UART CTX-10 design in my own project?

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