2.1.4 Expansion Interfaces for System-Level Prototyping
Two interfaces facilitate the adding of custom hardware to the LTE System board:
System expansion interface (1.8V I/O) is a 60 pin expansion connector (Samtec ERF8 /
ERM8 series) on the underside of the system board. WNC module peripherals are accessible
via this interface at 1.8V signalling levels, if 3
.3V (or 2.5V) levels are required by the user’s
custom circuitry, then voltage translator devices must be added to the user’s board.
Pmod™-compatible interface
(3.3V I/O) is 6x2 pin connector facilitates an easy to use
interface via I2C or SPI peripherals
, for access to a wide range of Pmod™ peripheral boards.
The relaxed pitch of this connector and low pin count of these interfaces also permits wiring-in
other 3.3V expansion boards (eg. MikroElektronika Click modules or Grove sensor boards) for
prototyping system-level solutions
