Mini DC Boost Step-Up Module 5V/8V/9V/12V 1.5A LED DIY PCB
Mini DC Boost Step-Up Module 5V/8V/9V/12V 1.5A LED DIY PCB
Multifunction Mini DC Boost Step-Up Module – 5V / 8V / 9V / 12V @ 1.5A
This compact, reusable DC-DC step-up (boost) converter board is a must-have for electronics hobbyists and DIY makers. Whether you're powering a microcontroller project, building a custom battery pack, or prototyping a portable device, this mini boost module delivers clean, selectable output voltages with ease.
Key Features
- Selectable Output Voltages: Choose from 5V, 8V, 9V, or 12V — default is set to 12V at the factory.
- Wide Input Voltage Range: Accepts 2.5V up to VOUT–0.5V input (e.g. single 3.7V lithium cell).
- Maximum Current: Up to 1.5A total (input + output must each stay within 1.5A).
-
Typical Output Performance (3.7V Li-ion input):
- 5V → 1.2A
- 8V → 0.7A
- 9V → 0.6A
- 12V → 0.5A
- LED Power Indicator: Built-in LED shows operating status; the indicator pad can be bridged or cut to enable/disable it.
- Solder-Pad Voltage Selection: Output voltage is set by bridging or opening pads labeled A and B on the PCB (0 = pad open, 1 = pad soldered) — no additional hardware required.
- Reusable & Breadboard-Friendly: Standard PCB form factor, easy to integrate into any DIY or prototype build.

Frequently Asked Questions
Q: What input voltage does this mini boost module accept?
A: The step-up boost module accepts an input voltage ranging from 2.5V up to VOUT–0.5V. For example, when using a 3.7V lithium battery, it can step up to 5V, 8V, 9V, or 12V output.
Q: How do I change the output voltage on the step-up board?
A: Output voltage is configured by bridging or opening the solder pads labeled A and B on the front of the PCB using a soldering iron. A value of "0" means the pad is left open, and "1" means the pad is soldered/bridged. Refer to the voltage selection table printed on the board.
Q: Can I turn off the LED indicator on the boost module?
A: Yes — the LED indicator has a dedicated solder pad next to it on the PCB. You can open (desolder) this pad to disable the LED entirely, which can be useful for low-power or light-sensitive applications.
Q: Is this boost module suitable for powering Arduino or Raspberry Pi projects?
A: Yes, this DIY step-up converter is popular for powering microcontrollers and single-board computers from lower-voltage battery sources. When using a 3.7V Li-ion cell, you can set the output to 5V at up to 1.2A — suitable for many development boards and small electronic projects.
