ESP32 Wi-Fi Kit
Overview
Based on the popular ESP32 microcontroller, this kit includes Wi-Fi wireless communication, microSD, and a real-time clock function. It doesn’t run on coin cell batteries, but it runs on a slightly larger battery. As is, you can send the value of the touch sensor to your smartphone or PC via Wi-Fi for easy display.

Leaf list
AP02 ESP32 MCU
Espressif Systems’ 32-bit MCU leaf featuring the ESP32-WROOM-32 module with integrated Wi-Fi and Bluetooth LE, which is technically certified.
AV04 2V～4.5V
The power supply leaflet contains a JST SH connector for lithium-ion battery or battery box connection, a power switch, an AD converter for voltage monitoring and a 3.3 V step-up/down circuit.
AX07 Back to back
A connector leaf that can be connected back to back.
AX08 29pin header
A leaf with all 29 pins of the leaf I/F connected to a 2.54mm pitch pin header.
AZ02 RTCµSD
The RTC can output interrupts to the MCU with alarms and timers, while the microSD card is accessible via SPI.
AZ62 Connector Cover
The Connector Cover protects the ACR (Anisotropic Conductive Rubber) from dust and debris.
AZ63 Nut Plate
The Nut Plate is used to fix the leaf with a screw. Be careful not to use commercially available hex nuts as they may cause a short circuit by touching the electrodes on the board.
