Features:
Versatile and powerful ESP WROOM 32 WiFi-BT-BLE MCU module.
Core chip designed for scalability and adaptability with two independent CPU cores and adjustable clock frequencies (80 MHz to 240 MHz).
Rich peripheral integration, including capacitive touch sensors, Hall sensors, low-noise sensor amplifiers, SD card interfaces, Ethernet, high-speed SDIO/SPI, UART, and I2C.
Dual-mode WiFi and Bluetooth-compatible chip (ESP-WROOM-32) with 40-nanometer low-power technology for fast wireless internet connectivity and low-power Bluetooth communication.
GPIO expansion board allows for one GPIO pin to be expanded into two, making it a useful tool for smart home projects.
