In case you want to change the firmware be aware that the Hi Tech compiler used for the MOD-IO2 board comes with an incorrect microchip PIC 16F1503 header file. As a result the board will *not* respond on I2C requests.
In order to change use the file from the following topic:

Hey jsw,
Thank you for the note. This is indeed true.
You might also use this PIC16F1503 header: https://drive.google.com/file/d/0B7WHuNCASY8cOGR3OUtsYlRPMmM/edit?usp=sharing (https://drive.google.com/file/d/0B7WHuNCASY8cOGR3OUtsYlRPMmM/edit?usp=sharing).
Best regards,

would this explain this error?
error: undefined symbol "BORV_19"
I'm trying to compile the v3 firmware for mod-tc-mk2 which uses pic16f1503 and i2c.
The answer appears to be yes.
