Charger 25 Click is a compact add-on board that contains a battery charger. This board features the BQ25792, a buck-boost battery charger with a dual-input selector, and a USB PD3.0 OTG output from Texas Instruments. It is fully integrated for 1-4 cell Li-Ion and Li-Polymer batteries. Designed specifically for USB applications, it also includes a Narrow voltage DC (NVDC) power path management in which the system is regulated at a voltage slightly higher than the battery voltage without being allowed to drop below the minimum system voltage.

IR Thermo 4 Click is a compact add-on board for precise remote sensing applications. This board features the TPiS 1T 1386 L5.5 H thermopile sensor from Excelitas, known for its high accuracy and narrow 5° field of view (FoV). This sensor, part of the CaliPile™ family, features factory-calibrated data stored in EEPROM, ensuring reliable and accurate performance. The sensor also comes in an isothermal TO-39 package with an integrated lens hood for minimized stray light and enhanced thermal stability, making it ideal for challenging environmental conditions. With a built-in ADC and multiple filter options, the sensor's data is easily accessible via an I2C interface. IR Thermo 4 Click is well-suited for remote skin temperature monitoring, over-temperature protection, human presence sensing, and motion detection.
