DESCRIPTION
32-bit MCU & 2.4 GHz Wi-Fi & Bluetooth/Bluetooth LE ESP32 is a single-chip solution integrating 2.4 GHz Wi-Fi and Bluetooth dual-mode, using TSMC ultra-low power consumption 40nm process, with ultra-high radio frequency performance, stability, versatility and reliability, and ultra-low power consumption, to meet different power consumption requirements, suitable for various application scenarios.
The ESP32 module uses CH340 USB driver - You can head over to SparkFun's page for installation instructions: https://learn.sparkfun.com/tutorials/how-to-install-ch340-drivers
Note: This module uses USB Type-C cable.
