Hi,

my SparkFun Thing Plus - ESP32 WROOM (v2.0) seems to have a problem with its onboard peripheral power (output).
I was attempting to provide 3V power to a Gravity: Digital Relay Module being used as a simple switch.

The Thing Plus is booting, connecting, configurable, receiving data from two sensors, no problems. I diagnosed the issue with a multimedia after the relay would not power on. The voltage is correct but i am unable to get a reading in A or mA. When i use the multi-meter i see nothing for Amps, and an overload signal for miliamps.

it is a new card, used to upgrade a working system.
