ANT BBPS is a small, elegant breadboard power supply (BBPS) carefully designed to connect to the end of any M102 breadboard. It’s unique shape plugs directly into the power connection pins and does not interfere with anything else.

But that’s not all! ANT BBPS displays voltage, current and power on an OLED display. It has a digitally controlled current limit, a wide input voltage range, and up to 12 V DC output. It also has two input connections, a USB type-C connector and a screw terminal. The USB input means a battery bank can easily be used as your power source, and the screw terminal allows any other input source to be connected, such as AA and 9 V batteries, or even an old 7 V wall adapter you might have lying around.

With only one button and one potentiometer dial ANT BBPS is particularly easy to use. The potentiometer sets the output voltage and the button enables it. The button is also used to access the menu. As a final feature, ANT BBPS is designed to be small, light and portable. All of this makes ANT BBPS ideal for prototyping digital and analog circuits.
