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

Connect 5 V Grove-compatible sensors and other modules to Leafony for UART or I2C communication and analog or digital inputs. This leaf supports the Seeed Studio Grove series and boosts 3.3 V to 5 V to power the connected modules. The I2C expander lets you turn off the 5 V supply to reduce power consumption while the modules are not in use.
