There are just two signal lines but support multiple protocols and signals I2C, UART, PWM generation and sampling, controllable pull up/down. The micro is a PIC24FJ64GB002 and it's internal peripherals can me remapped though a multiplexer to the two signal lines of the DataPod.

No onboard EEPROM but the 64K program flash (less space taken by the USB bootloader) can store data given some limitations. It has no byte access so it must be programmed in blocks and erased in even larger block. The CPU pauses during the few milliseconds that an erase or programming takes place.

The hardware is not really suited to make a data-logger but you can make a nice viewer for another PCB that does the logging.
