ERM8 is a board mounted plug designed specifically for high-speed systems. ERM8 uses Edge Rate ® The terminal system is designed specifically for applications that require high docking cycles and 56Gbps PAM4 performance. Connect the socket on the ERF8 and ERM8 boards.

The LTE IoT branch carrier board is an expansion board that can achieve system level prototyping through the 2nd generation AT&T LTE IoT starter kit (US) or the global LTE IoT starter kit. These LTE 4 IoT starter kits are equipped with a multifunctional Avnet SOM that supports cellular connectivity, GPS location tracking, built-in sensors, dual expansion interfaces, user application hosting, and Starter SIM for data and SMS services

Starter SIM uses its Samtec ERM8 series 60 terminal connector to convert a subset of the peripheral interface of a WNC LTE module (signal level of 1.8V) to 3.3V and fix it to two Click module sockets, which can purchase over 300 different MikroElekronika Click peripheral modules.
Onboard 3.3V and 1.8V regulators ensure power quality for all use cases.

The external control of LTE system board power failure and sleep mode is achieved through a 2x6 terminal connector (unused), which also provides access to the module's digital audio interface (currently not supported by digital audio)
