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.

Features

Send and receive data wirelessly with compatible smartphones or computers using BLE (Bluetooth Low Energy). Combined with an MCU (microcontroller) leaf and a sensor leaf, this leaf can send sensor measurements to a receiving device.

It uses Silicon Labs’ certified BGM11S22F256GA-V2 BLE module and connects to the MCU leaf via UART. Radio certifications include CE, FCC, ISED Canada, TELEC, KC South-Korea, and NCC Taiwan (SLICON LABS Module Data Sheet Revision 1.2).
