Hello,

Can you provide the footprint / MPN of the specific USB-C receptor and microSD used in the SparkFun Thing Plus - STM32?

Also, I notice no ESD protection chips are used. Can you explain why it is not necessary?

Thanks!

The inclusion of ESD protection/not is usually a a function of the item’s cost
