Programmable wireless communication module compatible with LTE-M.
LTM-1 Wireless Module
Embedded communication module with UART interface compatible with cellular LPWA LTE Cat.M1.
Equipped with the nRF9160 from Nordic Semiconductor. LTE-M is a best-effort type of communication using carrier lines. This module has the Serial LTE modem and MCUBoot loader included in the nRF Connect SDK written to it. Operation is performed by issuing AT commands via UART. Please check the version of the Serial LTE modem written in the communication module using the AT#XSLMVER command and use the commands corresponding to that version. For information regarding the firmware license, please refer to the following: https://github.com/nrfconnect/sdk-nrf/blob/main/LICENSE License ID: LicenseRef-Nordic-5-Clause. Please be aware that we cannot address any issues arising from the firmware. * Please note that a SIM card (nano SIM) is required for the use of this product, so we ask that you contract for one.
