Modem News: Qualcomm Snapdragon X75 (SDX75) - Chester Tech Mods

Firstly, yes I've got the SDX75 working flawlessly in the Cheetah V2 and in the Ninja POE.

There are currently 2 Chester SDX75 offerings
Fibocom SDX75 - FM190W-GL
Quectel SDX75 - RM551E-GL

There is no difference between both offerings. Both are running a BETA Firmware.

Note: when you order The Next Episode/SDX75 the firmware on board is specific so the SDX75.
