Power Supply ModuleΒΆ

A 3.3V and 5V breadboard power module with series diode and reverse polarity protection. The module can accept 6.5V to 12V input, and can generate 3.3V and +5V. For experimenters who must test/prototype electronic circuits on breadboards or perforated/veroboards, this is a must-have power supply module.


  1. Plug directly to MB102 Standard breadboard.

  2. Input voltage: 6.5-12 V (DC) or 5V USB power supply.

  3. Output voltage: 3.3V and 5V can switch over.

  4. Maximum output current: <700 mA.

  5. External Input voltage ON/OFF switch.

  6. Independent control of upper and Lower Bread Board Power Rails. Can switch over to 0V, 3.3V, 5V using jumpers on any rail.

  7. On-board two groups of 3.3V, 5V DC output plug pin, convenient external lead use.

  8. USB device connector onboard for power output to external device.

  9. Size: 5.3cm x 3.5cm.
