Batteries & Power supplies

Lithium batteries can’t be charged as regular batteries or devices. Instead, you’ll need a li-ion charger such as this one. Integrated with the CC/CV charging technology, it is the simplest way to charge a lithium-ion battery.

The board has a USB Type-C connector for power, a JST-type connector for batteries, the charging circuit, and two status LEDs.

Product usage tips:

The red LED glowing means the battery is charging. The green LED glowing means battery is charged. Easy embedding into a project with the four mounting holes on the board. Comes with 5 pins that need to be soldered.

Note: This charger has no protection against reverse polarity, short-circuit, too high or too low voltage. If you’re looking for a charger with a protector, click here.

A classic small power with an output of 5V / 2A which will ideally supply your project with an Arduino / Croduino. The output is standard female USB connector (type A). You can directly connect a cable from the PCB to the charger and use it as a constant power source, or it can be used for charging up a mobile phone/tablet. Or for a third purpose ..? In any case, it will be enough!

Lithium batteries are charged differently than regular batteries and devices. You’ll need a li-ion charger like this one to charge them. Integrated with the CC/CV charging technology, it is the simplest way to charge a lithium-ion battery.

Small, industrial power supply in the metal housing allows the conversion of 230V AC to 12V DC voltage of maximum current 5A, power 60W.

A classic small power supply with an output of 5V / 2A which will ideally supply any USB-powered device. The output is standard female USB connector (type A).

If you need a simple and stable power source for your breadboard projects, this board is here to help. Supply it with DC jack DC power or using UCB-C cable, and the board provides 3.3V, 5V or 12V directly to the power supply lines on the breadboard. Output voltages are adjustable seperately using the onboard switches. There’s a power LED, a power switch and an automatic voltage selection circuit, in case both power inputs are there.

A battery protector is, simply put, a device that makes sure that something bad doesn’t happen to the battery. This small circuit board protects your lithium battery (of any capacity) from overcharge, overdischarge, overcurrent and short circuit. It has a JST connector for connecting the battery, and the battery can be directly soldered.
