Expansion Connectors
The ODROID-C2 provides 40-pin dual row expansion header “J2” and 7-pin single row expansion header “J7”.
The location and pinout of these connectors are illustrated blow. (Board Revision 0.2 : 2016/02/26)
All signals on expansion headers are 3.3V except Analog input signal.
If you use the engineering sample, refer a pin map on this link. Expansion Connectors (Board Revision 0.1 : 2015/10/26)
ODROID-C2 doesn't support the HW SPI pin interface.
