ODROID-M1

Expansion Connectors

The ODROID-M1 provides 40-pin dual row expansion header “J1”.
The location and pinout of these connectors are illustrated below. (Board Revision 1.0 : 2021/11/12)
All signals on the expansion headers are 3.3V except for the analog input signal. The ADC inputs are limited to 1.8Volt.
