Feather 3V3 Regulator Test

This test is intended to validate the 3V3 regulator.

Setup

IDE

Compile and flash using the Arduino IDE v2.x

Breadboard

  • Place an LED with the positive leg on the row with the 3V3 pin of the Feather, and the negative leg in row 1 of the breadboard.
  • Place one leg of a resistor in row 1 of the breadboard, and place the other leg of the resistor in the row with the GND pin of the Feather.

STLINK

  • Connect the STLINK to the STDC14 connector (a.k.a. JTAG) on the Feather. This will be used to collect logs.

Usage

On boot, you should see a "ready message" on the serial monitor (e.g. "Running Feather 3V3 Regulator Test"). Once this message has appeared, the test is running.

The LED should toggle on an off in one second intervals.

Test Assertion

There is no assertion associated with this test.
