This document describes the nRF93M1 LTE Cat 1 bis cellular module: its features, electrical and mechanical characteristics, host integration interfaces, and operating conditions.
nRF93M1 ships pre-programmed with signed Nordic firmware that implements the LTE protocol stack, IP and upper-layer protocols, location features, and other functions. The host MCU controls the module through a documented AT command interface and standardized network interfaces; it does not execute customer code on the module itself. Firmware is updated in the field through Firmware Over-The-Air (FOTA) using HTTP/S, nRF Cloud service, or serial DFU.
The chapters in this document are organized by function, features and peripherals. Each chapter describes the feature, some relevant AT commands or signal interfaces, electrical characteristics where applicable, and any integration details or other relevant information.
