3.3 2x6 Pin Peripheral Connector
The 2x6 Pin Peripheral Connector is compatible with a subset of Pmod
™ peripheral boards from
Digilent, Maxim, Measurement Specialties (TE Connectivity) and others.
The pinout of this 2x6 pin right-angle socket connector is derived from the I/O signal assignments
defined in the
Digilent Pmod
™ Interface Specification
for SPI and I2C serial interfaces.
Note however, that dual-row I2C Pmod peripheral boards in many cases may not be fitted to this
board, as their duplicate SCL and SDA pins are not accommodated by the combo SPI plus I2C
interface pinout assignments implemented on the LTE System board.
