The WT32-S1 WiFi module core processor ESP32 is a single-chip solution that integrates 2.4 GHz Wi-Fi and Bluetooth dual-mode in a smaller package. It uses TSMC’s ultra-low power 40 nanometer process and also integrates The antenna switch, RF Balun, power amplifier, low noise amplifier, filter and power management module are included. ESP32 also integrates a wealth of peripherals, including capacitive touch sensors, Hall sensors, low-noise sensor amplifiers, SD card interface, Ethernet interface, high-speed SDIO/SPI, UART, I2S and I2C, etc.

The ESP32 chip integrates traditional Bluetooth, Bluetooth low energy and Wi-Fi, and has a wide range of uses: Wi-Fi supports a wide range of communication connections, and also supports direct connection to the Internet through a router; Bluetooth allows users to connect to mobile phones or broadcast BLE Beacon to facilitate signal detection. The sleep current of the ESP32 chip is less than 5μA, making it suitable for battery-powered wearable electronic devices. The operating system of ESP32 is freeRTOS with LWIP, and TLS 1.2 with hardware acceleration is built in. The chip also supports OTA encryption upgrades, and developers can continue to upgrade after the product is released
