It’s Manufacturing Monday at Adafruit and we’re testing up a storm!
Every Adafruit board gets tested to ensure it’s in good working condition before shipping. Here you can see a large batch of nrf52 Bluefruit LE Feather boards being tested.
We test each of these boards by hand as seen in this time-lapse video. Learn more about Bluefruit Feathers on the Adafruit Learn System
