The Charging and Battery Boost Module is a versatile electronic component designed to charge and boost the voltage of a single-cell lithium-ion 18650 battery. It efficiently converts the battery's nominal voltage of 3.7V to a higher output voltage range of 5V to 9V, making it suitable for powering a variety of devices. The module is equipped with the TP4056 chip for reliable and efficient charging and features a Type C port for modern connectivity.

B+ pin.B- pin.OUT+ and OUT- pins.OUT+ and OUT-).To power an Arduino UNO using this module, follow these steps:
OUT+ pin to the Arduino's 5V pin.OUT- pin to the Arduino's GND pin.Here is a simple Arduino code example to blink an LED while powered by the module:
// Blink an LED connected to pin 13 of the Arduino UNO
void setup() {
pinMode(13, OUTPUT); // Set pin 13 as an output pin
}
void loop() {
digitalWrite(13, HIGH); // Turn the LED on
delay(1000); // Wait for 1 second
digitalWrite(13, LOW); // Turn the LED off
delay(1000); // Wait for 1 second
}

Q: Can I use this module with other types of batteries?
A: No, this module is specifically designed for single-cell 18650 lithium-ion batteries. Using other types of batteries may damage the module or the battery.
Q: Can I charge the battery and power a load simultaneously?
A: Yes, the module supports simultaneous charging and discharging. However, ensure the input power source can handle the combined current requirements of the load and charging process.
Q: How do I know when the battery is fully charged?
A: The onboard LED indicator will change from red (charging) to blue (fully charged) when the battery is fully charged.
Q: Can I use this module to power a Raspberry Pi?
A: Yes, but only if the output voltage is set to 5V and the current requirements of the Raspberry Pi (including peripherals) do not exceed 2A.
