Diode (Schottky)
1N5817 Schottky diode, 1 A
Lets current go one way only: from the stripe-less end to the end with the grey stripe.

| Pin or leg | What it is for |
|---|---|
| Anode | the end without the stripe: from the power |
| Cathode (stripe) | to what it feeds |
- The stripe points to where the current goes: towards the Micro:bit’s 3V pin.
- It takes about 0.3 V: 3.3 V becomes about 3 V, fine for the Micro:bit.
Good to know: Between the regulator and the Micro:bit's 3V pin: the regulator and the USB cable can never feed each other.
The idea behind it, step by step: 5 V parts with a Micro:bit
