Features
Supply 3.3V power at up to 1.0A to other leaves from an external battery. An MCU (microcontroller) leaf can also read the battery voltage. The leaf supports two or three dry cells.
It includes a JST PH connector for the battery, a buck-boost power supply circuit that converts a battery voltage of 1.8–5.5V to 3.3V, and an I2C analog-to-digital converter for measuring the battery voltage.
