5V 2A wireless power supply module

This 5V 2A wireless charging transmitter module complies with the Qi (WPC) wireless charging standard, delivering a maximum output of 5W charging power. It integrates FOD (Foreign Object Detection) protection, features low static power consumption, and excellent conversion efficiency. Equipped with dual LED status indicators, it provides intuitive feedback on various operating states, including standby, charging, fully charged, and foreign object detection. With a transmission distance of 0-8mm, it is compatible with most Qi-compliant wireless receivers. It can be used for DIY modifications, built-in wireless charging in devices, experimental development, and power supply upgrades for small appliances. The module is compact, with a separate coil design, making it easy to embed into various device housings for secondary development.

Key features:

1. Qi WPC standard compatibility: Compatible with WPC standard wireless receivers, suitable for most Qi wireless charging phones and receiver modules on the market.
2. FOD (foreign object detection) Protection: Identifies metal foreign objects above the coil, triggering an abnormality warning and avoiding overheating safety hazards.
3. Dual LED status indicators: Red light indicates standby power-on, blue light indicates charging; blue light flashes during foreign object detection, providing a clear status indication.
4. Low power consumption and high efficiency: Low static power consumption, high energy conversion efficiency, and controllable heat generation during long-term operation.
5. Separate coil structure: The circuit board and transmitting coil are separate, facilitating embedded installation and adapting to various DIY housing structures.
6. Wide operating temperature range: Normal operation from -20℃ to +85℃, suitable for industrial and outdoor development project environments.

Operating instructions:

1. Connect to a 5V/2A power supply. The module’s standby red light will illuminate, indicating it is ready.
2. Place a Qi-enabled wireless charging device with its coil center aligned with the center of the module’s transmitting coil. The module’s blue light will illuminate, initiating wireless charging. Off-center coil placement will reduce charging efficiency; centering is recommended.
3. FOD (Foreign Object Detection): A blue LED flashes as an alarm when a metallic foreign object is present on the transmitting coil. After removing the object, the blue light turns off, and the device returns to a red standby state.

Compatible models:

Compatible with all Qi-enabled mobile phones from Huawei, Apple iPhone, Samsung, Xiaomi, Nokia, Google Pixel, LG, Sony, etc. It can also connect to various third-party Qi wireless receiver boards for DIY modifications to non-wireless charging devices.
