Description
This board can be used to intercept communications between the AA Tablet and Control Box.
It has ethernet jacks for the connection to the Control Box and the Tablet, and screw-connector taps for:
- The RS485 data lines (to be connected to an RS485 USB device)
- The 12v (14v) power lines from the Control Box.
- A bridgeable connector that can be used to disconnect the power from the tablet-side of the connection if needed.

Questions
How big is the AAPiHat PCB?
It measures 64.9 × 30 mm and has 4 copper layers, 1.58 mm thick.
What parts does the AAPiHat use?
29 parts, built around the ADP2303ARDZ, RV1S9060A, MAX13487EEA and SSB43L-E3. 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 AAPiHat KiCad files?
From the gundy/aa_pihat repository on GitHub, at the commit this page was made from: the board is hardware/boards/pi_hat/AAPiHat.kicad_pcb and its schematic hardware/boards/aa_interceptor/AAInterceptor.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the AAPiHat design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
