Power requirements

TB-S3A1 is designed for 3.3 Volt operation. Note that this also means that 5V PMOD devices cannot be used together
with the TB-S3A1 unless they are powered separately.

The total current available from the LDO regulator for all connected circuits is 0.600A or less, depending the 5V power
source used.
