Hey #electronics folks, has anyone designed a board for a Quectel 5G WWAN M.2 card?
The M.2 spec says VCC typical is 3.3V maximum 3.6V, but the Quectel datasheet claims to want 3.8V typical 4.4V max. There’s claims in the Quectel datasheet that the card will shut down if VCC reaches 3.125V. It’s pretty power-hungry when the radio goes into transmit mode with 1.5A transient loads so it could possibly under-volt if I use 3.3V, but if I use 3.8V then the slot would only be usable with Quectel cards that demand the higher voltage.
Thoughts on 3.3V vs 3.8V in this situation?
