Power

Adjustable Volts Step-Down Power Supply 5-23V 3A

These are pretty good if you need something small on the bench to power projects at different voltages. The one below allows you to control the current.

Adjustable Volts and Amps Step Down Power Supply

This PSU allows you to control the amps as well as the volts. I use it with a 19v laptop PSU to power projects and charger supercapacitors for testing.

Protected 18650 Cells

I bought these because they are safer than using unprotected cells recovered from a laptop

BUY FROM: AliExpress


USB Volt Amp Meter

These are great for seeing how much power a microcontroller is using when it runs specific code. For example you can see a jump in current when an ESP32 connects to WiFi.
