Can you recommend an enclosure for an M.2 modem w/ dual SIM ? Also, since the EM7455 has an inrush / max current spec of 2.5 / 1.5 A, it would be nice to allow an external power supply of 12 VDC (or so). Also, since the heat spec is "up to 3.5 W", it would be nice to have some sort of heat sink and/or thermal pad. Thanks, Ken
