Leaf Technical Sheets
Espressif Systems' ESP32-WROOM-32 32-bit MCU leaf with a module ESP32-WROOM-32 with built-in technically certified Wi-Fi and Bluetooth LE, which includes a USB to UART conversion IC and can write sketches. A step-down power supply circuit provides VBUS and 3.3V. It also has a reset button.ESP32 Wi-Fi Kit
32-bit MCU leaf with ARM Cortex-M4 32-bit RISC core with STMicroelectronics FPU; connect USB leaf for USB connection or Shield leaf for SWD use.
The Leaf is equipped with EASEL’s technically certified LoRa module ES920LRA1.
This power supply leaf contains a CR2450 coin cell battery holder, a power switch, an AD converter for voltage monitoring, and a 3 V to 3.3 V step-up circuit.
The Grove is a Grove Series compliant leaf from Seeed Studio that operates at 5V with UART, I2C, analog and digital inputs, converted from 3.3V to 5V by a step-up power supply circuit and supplied to the Grove. To achieve low power consumption, it is possible to turn off the 5V power supply by controlling the I2C Expander.Extension Kit
