Ultra-mini boost module built around the SX1308 step-up converter.
Input voltage range typically 2V–24V, output adjustable up to 28V.
Small footprint, ideal as an auxiliary supply in ESP32 or other low-power embedded systems.
Core: SX1308 boost converter.
Input: VIN (typical 2V–24V), GND.
Output: VOUT (adjustable, up to 28V), GND.
Enable pin: EN (high to enable, low to shut down).
Feedback resistor network sets the output voltage; default value is pre-configured on the board.
Inductor and capacitors are integrated; only input and output connections are required.
This is a pure hardware boost circuit; no firmware or software flow.
For ESP32 projects, connect the output to the 5V or 3.3V rail (ensure voltage compatibility).
Add a bulk capacitor at the output to reduce ripple.
No MCU core; purely analog power module.
