Breadboard Power Supply Module, Dual Output Charging Board with Power Indicator,Anti Sleep Design for DIY Electronic Description

1. Powered by a single 18650 battery with dual 3.3V/5V outputs; an all-in-one power solution for breadboard circuit testing.
2. Dual charging (Type-C/Micro-USB) with an LED battery level indicator; all 5 LEDs light when fully charged for clear status monitoring.
3. Dual output (USB-A/Type-C); simple operation-short press to enable output, double-click to disable.
4. Pin headers plug directly into breadboard power rails; 5V/3.3V power is instantly available without extra wiring.
5. Anti-sleep design; a toggle maintains a dummy load to prevent the module from shutting down during light-load operation.

Product Specifications
Output Interfaces: USB-A / Type-C
Output Voltage/Current: 5V/3A, 3.3V/2A (shared total current across during discharge)
Charging Input: Type-C, Micro-USB (5V, to 3A)
Power Source: 1 x 18650 Lithium Battery (3.7V)
Power Level Indicators: D1-D5 (5 red LEDs)
3.3V Output: Derived from the 5V rail via the onboard PW2053 regulator; active only when output is enabled.
Usage Instructions
1. Battery Installation: Insert one 18650 lithium battery into the holder. Observe polarity: Pad 1 is positive (BAT+), Pad 2 is negative (BAT-); incorrect installation may damage the board.
2. Charging: Connect a 5V adapter to the Type-C or Micro-USB port using a USB cable; charging starts automatically. LEDs indicate progress; all 5 LEDs light when fully charged.
3. Discharging: Connect your device to the USB-A or Type-C port; if the output is not active, briefly press the button to enable it.
4. Breadboard Power Supply: After enabling the output via the button, the top-left header pins output 5V and the top-right pins output 3.3V; the bottom header pins can be inserted directly into breadboard power rails.
