Overview
This starter bundle has everything you need to begin prototyping: an 830-point solderless breadboard, an MB102 breadboard power supply module, and a 140-piece set of pre-formed jumper wires. The breadboard gives you a generous build area with power rails down both sides, the power module drops regulated 3.3V or 5V onto those rails, and the jumpers keep your wiring flat and tidy.
It is the ideal foundation for Arduino, ESP32, Raspberry Pi, and Pico experiments - build, test, and rewire circuits with no soldering.

How to Use
Seat the MB102 power module onto one end of the breadboard so its pins land in the power rails, supply it with 6.5-12V DC or USB, and set each rail to 3.3V or 5V with the onboard jumpers.
| Step | Action |
|---|---|
| 1 | Press the MB102 onto the breadboard power rails at one end. |
| 2 | Plug in a 6.5-12V DC adapter (or USB) to the module. |
| 3 | Set each rail jumper to 3.3V or 5V as your circuit needs. |
| 4 | Press the power button, then build using the jumper wires. |
Warning: Confirm each rail is set to the correct voltage before connecting parts. Feeding 5V to a 3.3V device can damage it.
Tip: The breadboard's two center columns are split by the middle gap - straddle that gap with ICs so each side of pins is independent.
Frequently Asked Questions
Can the module output 3.3V and 5V at the same time?
Yes. The two rails are independently selectable, so you can set one side to 5V and the other to 3.3V and power mixed-voltage circuits at once.
How do I power the module?
Use a 6.5-12V DC barrel adapter or the onboard USB input. It then regulates that down to clean 3.3V and 5V for the breadboard rails.
How much current can it supply?
Up to roughly 700mA total, which is plenty for sensors, LEDs, and logic. For motors or high-current loads use a separate dedicated supply.
Do the power rails run the full length?
On many 830-point boards the rails are split in the middle. If a far section seems dead, add a short jumper to bridge the two halves of that rail.
Is any soldering needed?
None. Everything is solderless - press components and jumpers into the holes, and remove or rewire them as often as you like.
