ESP32-S2-DevKitM/WROOM ESP32-S2 Development Board Wi-Fi MCU Module Wireless Module 32-Bit Single Core 1. Made of high-quality materials, finely crafted, easy to install, and easy to operate. 2. The module has a rich library of functions, a free and open-source environment, and also supports other compiler environments. The ESP32 module has a built-in Hall sensor, making WIFl suitable for project or development use. The ESP32-S2 chip is equipped with a Tensa 32-bit LX7 single core processor, with a working frequency of up to 240MHz. 3. Low power consumption, which can turn off the power of the CPU and use a low-power coprocessor to monitor the status changes of peripherals or whether certain analog quantities exceed the threshold. 4. ESP32-S2 integrates a variety of peripherals, including SPI, I2S, UART, I2C, LEDPWM, TWAI @ controller, ADC, DAC, touch sensors, temperature sensors, and up to 43 GPIOs. 5. ESP32-S2 also has a full speed USBON The Go (OTG) interface for USB communication, with a wide range of applications, suitable for college students/engineers/technicians/factory indivi.
