Description

The SYN SHOP Badge was designed as a soldering practice board for DefCon 34, 2026. The solder pads were enlarged to make hand soldering easier.
It used three I/O lines to control six LEDa in a 'winky light' display that flash a pattern.
It includes an SAO port I2C interface that can load patterns and control the timing of the display.
Four solder-jumpers pads bring out the unused I/O lines.
A UDPI port, compatible to the SNAP programmer and an optional six pin serial port are included.
