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.
