10-Pack Boost Converter Module, 3.7V to 5V/8V/9V/12V

Key features

• [PACKAGE CONTENTS AND SPECIFICATIONS]: Each set includes 1 multi-function mini boost module, totaling 10 individual units per package. Dimensions for each item are 22 x 11 x 3.6mm. Operates with an input voltage range of 2.5V to VOUT-0.5V and delivers selectable output voltages of 5V, 8V, 9V, or 12V. Maximum input and output current must not exceed 1.5A.
• [VOLTAGE CONFIGURATION AND LED STATUS]: Designed to efficiently step up power. For example, using a 3.7V lithium battery input yields 5V at 1.2A, 8V at 0.7A, 9V at 0.6A, or 12V at 0.5A. Features an onboard LED operations status indicator. You can bridge the adjacent pad to turn off the indicator for light-sensitive or low-draw requirements.
• [COMPACT SIZE AND STEADY PERFORMANCE]: This DC-DC step-up converter chip maintains excellent efficiency even at light loads and holds a steady voltage under heavy draws without generating excessive heat. The tiny footprint makes it highly adaptable for small enclosures and space-constrained electronic projects.
• [VOLTAGE ADJUSTMENT INSTRUCTIONS]: Modules arrive default set to 12V. To change the output, locate pads A and B on the front PCB. Use a precision knife or soldering iron to connect or disconnect the pads. Configuration: A=0/B=0 for 5V; A=0/B=1 for 8V; A=1/B=0 for 9V; A=1/B=1 for 12V (0 means disconnected, 1 means connected). Verify output with a multimeter before attaching devices.
• [APPLICATION SCENARIOS]: Ideal for DIY electronics and micro-controller projects. Use this voltage booster to power ESP32 cam devices, illuminate 3.7V LED strings, run Neopixels from lithium batteries, or integrate into custom battery chargers. Suitable for generating standard 5V or 12V lines from 3.7V cells in portable tech and robotics.
