Weight is for the MTDOT-xxx-X1P-SMA, which is the heaviest model.
Important:
The MTDOT requires 3.3 V minimum power to maintain certification and to help protect the SPI Flash file
system. The onboard LDO regulator output is 3 V derived from the 3.3 V to 5 V (+-5%) input voltage.
Starting with firmware version 2.0.16, SPI flash access is prevented if the onboard LDO regulator output
drops below 3 V. This code change protects the SPI file system from corruption that could occur from
power drop or loss.
