MB102 2-channel 5V/3.3V breadboard power supply

MB102 breadboard power supply

MB102 is a power-supply module for compatible breadboards with two power rails. Outputs can be selected to 5V or 3.3V in supported settings. Check jumper positions and polarity on both rails before connecting electronics.

Connection and use

Check input voltage, DC-plug polarity and USB-port function on the actual revision. Do not connect multiple power sources simultaneously without a verified schematic. Current capability depends on regulators, input voltage and cooling; no unverified maximum is promised.

Compatibility

This is not an ESP32 DevKit V1 expansion board. Fit depends on breadboard rail spacing and segmentation; measure output voltage before inserting your circuit.
