Adafruit bq25185 USB / DC / Solar Charger with 5V Boost
Keeping your projects portable and powered up just got easier. The Adafruit bq25185 Charger with 5V Boost is designed for USB, DC, and solar charging, making it a versatile solution for powering 5V electronics. With a built-in boost converter, it eliminates the need for a separate power supply board.
Key Features:
- Multi-Source Charging – Supports USB, DC (5-18V), and solar power for flexible charging options.
- Optimized Solar Charging – Adjusts current draw to prevent voltage dips, providing near-MPPT efficiency without extra components.
- Power Path Management – When external power is available, it prioritizes the load while charging the battery with any leftover current, extending battery life.
- Regulated 5V Output – Integrated TPS61023 boost converter delivers up to 1A at 5V for your circuits.
- USB Type-C Connector – Includes 5.1k CC resistors for universal compatibility and access to data lines via breakout pads.
- Customizable Charge Rate – Defaults to 1A, but can be adjusted to 500mA by cutting a jumper on the back.
- Three Status LEDs – Orange (charging), Red (fault), and Green (3.3V output) for easy monitoring.
- Enable Pad – Allows you to disable the 5V boost converter when needed.
- Compact & Easy to Use – Just connect a 500mAh+ LiPo battery to the JST PH 2-pin port, charge via USB or DC/solar, and draw regulated 5V from the terminal block.
Using with Solar Panels
For solar power, a 5-7V panel is recommended—higher voltages just generate excess heat without performance gains. You can wire the panel directly or use a 2.1mm adapter cable with a 2.1mm terminal block for easy connections.
Need More Power?
If you require a higher charge rate (up to 1.5A) or a built-in DC jack, consider the bq24074. While it lacks a boost converter, you can pair it with the TPS61023 for step-up voltage needs.
This board is plug-and-play, with mounting holes for easy integration. Whether you're powering sensors, microcontrollers, or wireless projects, the Adafruit bq25185 Charger with 5V Boost keeps your electronics running reliably.
