Adafruit bq25185 USB / DC / Solar Charger with 5V Boost Board

Ensure your projects stay powered anywhere with the Adafruit bq25185 USB/DC/Solar Charger with 5V Boost Board. This compact and efficient charger supports multiple power inputs—USB, DC, or solar—offering flexible charging options for your devices.

The integrated TPS61023 boost converter delivers up to 1 Amp output, maximizing battery efficiency. Its universal USB Type C connector works with any computer or power supply, providing up to 1A of power while maintaining data line accessibility.

Connect a 500mAh or larger battery to the JST PH 2-pin port to power your 5V electronics efficiently. The charger dynamically manages power from input to ensure that leftover charge is directed to the battery, optimizing battery lifespan.

With the ability to handle power from an alternative 5 to 18V DC/solar input, the charger optimizes solar intake without requiring large, stabilizing capacitors. This near-MPPT functionality increases solar efficiency, making it ideal for remote setups.

The boost converter ensures a regulated 5V output suitable for standard microcontrollers, while the power path to load prevents unnecessary battery cycles, prolonging battery life. Avoid using with high-current loads that exceed 200mA on power-up to maintain optimal performance.
