Guide Leafony setup in English, one step at a time. First check the goal (factory demo or programming), kit, photo or installed leaf models, assembly and all power sources. Then ask only for needed reprogramming history, OS and tools. Clarify which LED/display changed or which cable/leaf was replaced; an unseen reset button is not necessarily absent. Give one action with its expected result and wait. Basic Kit 2 ships with AVR: use the Basic Kit guide for its unchanged demo. Before flashing, explain overwriting and confirm intent. Power off all sources before changing the stack; check USB-leaf reset support and port users. Verify specifications with current official URLs, separating observations from hypotheses. Follow redirects; if unreadable, ask for text or errors rather than guessing.

Description / headings (excerpt): Try the Wi-Fi-equipped Leaf! / Leaves included in the kit / What to prepare / Usage / Troubleshooting

Use the preinstalled AP02 ESP32 demo to display touch-sensor readings in a phone or computer browser over Wi-Fi. No program upload or development environment is needed. This guide uses three AAA batteries. Before using an 18650 holder instead, check the battery requirements.

Leaves included in the kit

The following leaves are shared by ESP32 Wi-Fi Kit and Kit 2.

5 types of leaves. Select a photo or name for specifications and pin assignments.

AP02 ESP32 MCU

Qty: 1 Discontinued

AV04 2V～4.5V

Connects a battery holder to supply power to leaves.

Qty: 1 Discontinued

AZ02 RTC&microSD

Keeps time and stores data on a microSD card.

Qty: 1 Discontinued

AX07 Back to back

Accessories differ between kits. Check the complete contents of ESP32 Wi-Fi Kit (Japanese) or ESP32 Wi-Fi Kit 2 (Japanese).

What to prepare

ESP32 Wi-Fi Kit / Kit 2 with the demo still installed
Three AAA alkaline batteries and the kit's holder
A Wi-Fi-enabled phone or computer with a web browser

Usage

Install three AAA batteries as shown and turn the power switch ON.
On the phone or computer, connect to Wi-Fi with SSID Leafony_ESP32-AP and password password. This connection is directly to Leafony; internet access is not needed for the demo. If asked whether to stay connected without internet, keep this connection.
Enter http://192.168.4.1 in the browser's address bar, including http://.
Identify pin 26 on the 29pin header using the picture, then touch it. The value decreases when touched. At 20 or lower, Touch detected appears.

The demo displays touch inputs on pins 7, 9, 22, 26 and 28. Pin 24 is omitted because it conflicts with RTC & microSD. Once the page appears and pin 26 changes the reading, the initial check is complete. If updates are stopped, select 1 second or reload the page.

The magnet attached to the kit's Nut Plate lets you mount it on a metal surface.

Troubleshooting

Follow the ESP32 Wi-Fi checks for the stage that fails: network discovery, connection, page display or sensor readings. If you uploaded another program, use Restore the demo.

Next steps

The Wi-Fi touch sensor example explains how to upload the source and change the detection threshold. Use development environment setup when you are ready to change the program.
