2.5.1 I/O Expansion Header (J24)
There is an I/O expansion header on the ESOM-MT-350. It is for connecting the
I²C, SPI, UART, PWM, ADC, and 5 CPU GPIO +11 I/O expander GPIO devices.
The I/O expansion header is compatible with the Raspberry Pi 40-pin connector.
The pin define are listed in the following table.
