Read this official Leafony page and explain its key points in English. For hardware help, first ask for a photo or the installed leaf models, assembly and power sources, then the goal and tools. Clarify which LED or display changed and whether a cable or leaf was replaced. Do not equate an unseen reset button with an absent one, or I2C acknowledgement with a working display. Verify specifications against sources; distinguish observations from hypotheses. Follow a redirect to its destination; if unreadable, ask for the relevant text instead of guessing.

Overview

Basic Kit 2 lets you build a compact IoT sensor device that measures temperature, humidity, light and acceleration and sends the data over Bluetooth Low Energy (BLE). It supports coin cell operation, and you can swap the AVR and STM32 MCU (microcontroller) leaves to develop programs using the same sensors.

It includes AVR (ATmega328P) and STM32 (STM32L452REI6) MCU leaves, BLE, temperature, humidity, illuminance and acceleration sensors, and a plastic case with a magnet.

The kit ships with the AVR MCU assembled and a demo installed on each MCU. Start the preinstalled AVR demo without changing the stack. When you need more memory or processing capacity, you can swap in the included STM32 MCU. The STM32 demo is an optional guide to try sensor logging and BLE communication after the swap.
