PawPad programming header

This is a project that aims to spice up the world of boring test jigs and programming headers with a completely new, full stack system for adding programming headers to your boards.

Why should I use this?

There are many benefits in the above shape compared to regular arrangements:

• No acid traps due to smooth curves
• No holes in the PCB means easier routing
• Big enough to solder wires to when needed, yet compact enough to be practical
• Large surface area makes it hard to peel the pads off and easier to hit with a jig
• Pretty

Files

PawPad - contains the KiCAD footprint.

Programming Jig - contains a programming jig meant to be screwed onto a piece of 10x10 aluminium extrusion/makerbeam.

NOTE: this jig is not complete! It has not yet been tested for actual programming and may not be ideal!

Pinout

The pinout is standardized as outlined below:

Pin	SWD	JTAG	SPI / ICSP	UART	I2C
Bean (1)	SWO	TDO	MISO	RX	-
Bean (2)	SWDIO	TDI	MOSI	TX	SDA
Bean (3)	SWCLK	TCK	SCK	-	SCL
Bean (4)	NRST	TMS	RST	RST	RST
Big Bean (5)	GND	GND	GND	GND	GND

Future plans

• Alternative designs with different numbers of pins
• Unified pinout standard
• OSHW certification
• Debugger design
