Reply To: Recommended microSD card

Genuine Sandisk and Kingston cards have served us well, not drawing excessive power when the board is sleeping, and being reliable over many years in field deployments.  What we’ve seen issues with is generic cards from random manufacturers because they either fail and corrupt the data after a short time, or they draw 5 or 10 times more power than other cards.  I think any high-quality brand that’s 32GB or smaller should work fine, but you might want to keep an eye on your battery voltage for the first few days after you switch to a new card to see if your battery voltage levels perform the same.
