* | * ✅ Raspberry Pi 5 Dedicated PD Handshake Power Supply: Natively compatible with the Raspberry Pi 5's non-standard 5V5A PD power supply protocol, avoiding the "insufficient power" pop-up alarm triggered by ordinary power supplies; the included USB-C adapter board can be directly stacked on the bottom of the Raspberry Pi 5 for plug-and-play functionality. | ||
* ✅ 100F High-Capacity Supercapacitor Power-Off Protection: In long-run mode, it can provide up to 3 minutes and 31 seconds of continuous use under a 5V 0.5A load, allowing ample time for data writing and safe system shutdown; the supercapacitor solution eliminates the safety hazards of lithium batteries, offering long lifespan and maintenance-free operation. | |||
* | |||
* | * ✅ Dual Input Compatibility for Multiple Scenarios: Supports DC 9-24V wide voltage input / USB-C 12V PD fast charging input (choose one; USB-C requires a ≥30W PD/QC charger); internal dual-path isolation circuitry allows for seamless switching between charging and discharging. | ||
* ✅ Multi-interface 5V5A output: Standard configuration includes two outputs: USB-C (with PD handshake) and USB-A, sharing a total 5A power output; additionally, there are reserved unsoldered power supply pads for the top pins. Compatible with Raspberry Pi 3B/4B/5, Orange Pi, and other 5V development boards, and can also power other 5V devices. | |||
* ✅ Hardware-level power-down detection and intelligent power on/off: GPIO26 hardware direct connection detects power loss; onboard microcontroller manages the power-on signal, automatically powering on when power is restored from a power-off state; the accompanying official demo script supports automatically clearing the power-on pop-up window to avoid forced shutdown triggered by consecutive power losses, suitable for remote unattended operation scenarios (script needs to be deployed manually). | |||
* ✅ I2C real-time voltage and current monitoring: Onboard INA219 chip, reading capacitor voltage and charging/discharging current via the I2C interface for easy estimation of remaining battery life; official support scripts are provided for both Raspberry Pi OS and Ubuntu dual-system compatibility. | |||
* ✅ Comprehensive safety design: Integrated main power switch, fast discharge button, 5-level power indicator light, automatic cut-off when capacitor charging reaches 5.2V to prevent overcharge, making operation and storage safer. | |||
