Overview
Jack is an open-source printed circuit board by hamster, from the hamster/defcon30 repository on GitHub, published under the MIT licence. It is a 2-layer board of 35.7 × 37.4 mm with 11 parts on 8 nets, routed with 24 tracks and 0 vias.
Its parts include 4 diodes, 2 resistors and 1 crystal.
README
modem/README.mdSAO Modem 1.69bis
This SAO is designed to add some blinky lights to your badge, calling back to the days of an external Courier modem screaming away on the internet.
There are 6 lights:
- AA - Power, lights when 3.3v is present
- OH - Flashes on I2C SCL activity
- SD - Flashes on I2C SDA activity
- RTS - Flashes on GPIO1 activity
- CTS - Flashes on GPIO2 activity
- SYN - Connected to a free pad on the back, you choose what it does
The I2C inputs were selected to minimize load on the I2C bus, but this SAO might cause issues with badges with high speed I2C. In that case, you can swap R7 and R8 for higher value resistors.
You will need to solder on the SAO connector. Note that the notch or tab goes towards the top. See photo for reference. I like to insert the connector, solder one pin, then pinch the connector to the board with my fingers and re-heat this connection so that the connector snaps flat to the board before I solder on the rest of the pins.

Questions
How big is the Jack PCB?
It measures 35.7 × 37.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Jack use?
11 parts. 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 Jack KiCad files?
From the hamster/defcon30 repository on GitHub, at the commit this page was made from: the board is jack/jack.kicad_pcb and its schematic jack/jack.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Jack design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
