Product Usage Instructions

Before using the Whadda WPM321, please ensure you have read and understood the user manual and all safety signs. If the device was damaged during transit, do not install or use it. Instead, contact your dealer for further assistance. To charge a single-cell lithium-ion battery using the WPM321 module, follow these steps:

  1. Make sure the battery is connected correctly to the module by aligning the positive terminal (BAT+) with the BAT+ connection and the negative terminal (BAT-) with the BAT- connection.
  2. Connect the module to a power source using the appropriate cables.
  3. Once connected, the module will initiate the charging process. It will provide a constant current to the battery until it reaches a specific voltage.
  4. When the battery reaches the desired voltage, the module will switch to a constant voltage mode to complete the charging process.
  5. Monitor the charging progress and ensure proper ventilation during the charging process.
  6. Once the battery is fully charged, disconnect the module from the power source and remove the battery from the module.

What is Arduino®
Arduino® is an open-source prototyping platform based on easy-to-use hardware and software. Arduino® boards are able to read inputs – a light-on sensor, a finger on a button or a Twitter message – and turn it into an output – activating of a motor, turning on an LED, and publishing something online. You can tell your board what to do by sending a set of instructions to the microcontroller on the board. To do so, you use the Arduino programming language (based on Wiring) and the Arduino® software IDE (based on Processing). Additional shields/modules/components are required for reading a Twitter message or publishing online. Surf to www.arduino.cc. for more information.
