How to Use PowerBoost 1000 Basic JST Terminal: Examples, Pinouts, and Specs

The PowerBoost 1000 Basic JST Terminal is a versatile and compact power supply module designed to boost battery voltages to a stable 5V output, capable of delivering up to 1A of current. This makes it an ideal choice for powering 5V electronics from a lower voltage source, such as a single-cell LiPo battery. Common applications include portable USB chargers, battery-powered electronics, and DIY projects where a stable 5V power supply is required.

• Input Voltage: 1.8V to 5.5V
• Output Voltage: 5V regulated
• Output Current: Up to 1A
• Efficiency: 90% typical at full load
• Quiescent Current: 5mA typical
• Switching Frequency: 1.2MHz
• Operating Temperature: -40°C to +85°C

1. Power Input: Connect your power source (e.g., a LiPo battery) to the VIN and GND pins. Ensure the voltage is within the specified range.
2. Power Output: Connect your 5V device to the 5V and GND output terminals.
3. Enable Pin: If you wish to control the power state of the module, connect the EN pin to a digital output on your microcontroller. Drive it high to enable the output or low to disable it.

• Heat Management: When drawing high currents, ensure the module is well-ventilated as it may generate heat.
• Input Voltage: Do not exceed the recommended input voltage range to prevent damage.
• Battery Monitoring: Use the BAT pin to monitor the battery voltage if necessary.
• Short Circuit Protection: Always include a fuse or current limiting device to protect against short circuits.

// Example code to enable and disable the PowerBoost 1000 Basic using an Arduino UNO

const int enablePin = 7; // Connect the EN pin of PowerBoost to digital pin 7

void setup() {
  pinMode(enablePin, OUTPUT); // Set the enable pin as an output
}

void loop() {
  digitalWrite(enablePin, HIGH); // Enable the PowerBoost
  delay(5000);                  // Wait for 5 seconds
  digitalWrite(enablePin, LOW);  // Disable the PowerBoost
  delay(5000);                  // Wait for 5 seconds
}

• No Output Voltage: Ensure the input voltage is within the specified range and connections are secure.
• Output Voltage Drops Under Load: This may occur if the input power source cannot supply enough current. Check the power source's specifications.
• Module Overheating: Reduce the load or improve ventilation around the module.

Q: Can I use the PowerBoost 1000 Basic to charge my phone? A: Yes, as long as your phone charges via 5V and the current draw is within 1A.

Q: What type of battery should I use with the PowerBoost 1000 Basic? A: A single-cell LiPo battery is recommended for optimal performance.

Q: Can I use multiple PowerBoost 1000 Basics in parallel for more current? A: It is not recommended to use boost converters in parallel due to potential issues with load sharing and synchronization.

Q: How can I monitor the battery level? A: You can connect the BAT pin to an analog input on your microcontroller to monitor the battery voltage.
