Keyes ESP32 Core Development Board Onboard ESP-WROOM-32 WiFi Module for Arduino KY0004
Keyes ESP32 Core board is a mini development board designed based on ESP-WROOM-32 module. This development board leads out 2.54mm pitch headers from I/O to both sides. The users can connect peripheral devices on their needs. When using and debugging, the standard headers on both sides can make your operation more concise and convenient.
The ESP-WROOM-32 module is the leading WiFi + Bluetooth solution with less than 10 external components. It integrates antenna switches, RF balun, power amplifiers, low noise amplifiers, filters and power management modules. At the same time, it also adopts TSMC low-power 40nm technology. The cost-effective and radio frequency performance makes it safe and reliable to expand various applications.
