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.

Description / headings (excerpt): CAD templates, pin assignments, a pin assignment editor, and the I2C address map for designing your own leaf / CAD Templates / Pin Assignments / I2C Address Map

This page brings together resources for designing your own leaf. Use a CAD template for the board layout, and check the pin assignments and I2C addresses of the leaves you plan to combine.

CAD Templates

The templates include the leaf outline, Leafony bus footprint, and design rules. Each page provides a download link and instructions.

Pin Assignments

Leaf pin assignments are collected in the pin assignment resources (GitHub: Leafony/Documents). When designing your circuit, check the pins and signals used by the leaves you plan to combine.

Use the Pin Assignment Editor to create a diagram for one leaf or a table comparing pin usage across multiple leaves, then save it as a PNG or SVG image.

I2C Address Map

The I2C Address Map lists the addresses of I2C devices on each leaf. If you use I2C devices on your own leaf, choose addresses that do not overlap with addresses already in use or reserved addresses.
