View prompt

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

This development kit combines temperature, humidity, pressure and 3-axis acceleration measurements with data communication over a cellular network. It uses the AI05 environmental sensor leaf, the AP03B STM32 microcontroller leaf to run programs, and the AC09 Cellular LPWA Cat-M1 leaf.

Cellular LPWA uses cellular networks for low-power IoT devices. This kit uses AC09 with Cat-M1 support. Communication requires a compatible nanoSIM, a service plan and programs to control each leaf. See the AC09 reference for SIM configuration examples and service requirements to check.

AV06 supplies power and accepts the included PH-connector battery holder for two AA cells.

Start with Cat-M1 Kit: prepare for development to check additional items and differences from the existing AP03 + AI01 example. Operating instructions for this kit’s AP03B + AI05 configuration are in preparation.

Leaves

Leaf	Role
AC09 Cat-M1 TY	Cellular LPWA Cat-M1 communication over a cellular network.
Spacer	Increases spacing to prevent component interference.
AI05 Env Sensors	Measures temperature, humidity, pressure and 3-axis acceleration. The standard configuration uses BME280 and LIS2DW12.
AP03B STM32 MCU	Runs programs to read sensors and control communication leaves. A redesigned version of AP03.
AV06 1.8V–5.5V	Supplies 3.3V to the leaves from batteries. The battery holder connects through a PH connector.

See the AP03B STM32 MCU reference for specifications, pin connections and design documents.

Accessories

Accessory	Purpose
M2 screws	Secure the stacked leaves.
Nut Plate	Used with M2 screws to secure the leaves.
PH-connector holder for two AA cells	Connects to AV06 for battery power.
