Give your Cardputer a second radio brain and a GPS.
The PalPack is a GPIO and RF expansion board for the Cardputer ADV and Cardputer Zero. Solder on a Seeed XIAO ESP32-C5 and an ATGM336H GPS, hang two antennas off it, and you've got 5 GHz and wardriving in your pocket. It talks to the Cardputer over UART, so no SD card slot is taken up. T
