Other than standard Input/Outputs, on SECOnITX-ION board there is also the possibility of using
up to 8 General Purpose Input/Outputs (GPIO), coming out from a dedicated microcontroller,
Texas Instruments MSP430F2122IPWR. Access to these GPIO can be done using a dedicated
library, which can be supplied by SECO.
The connector is a 10 pin, single row, p2mm, type MOLEX p/n 89400-1010 or equivalent, with
following pinout:
