Wireless-Tag, WT32-S1 WiFi module, low consumption, cost-effective embedded wireless network control module
WT32-S1 WiFi module is designed by Wireless-Tag, low consumption, cost-effective embedded wireless network control module. It can meet the IoT application requirements in the smart power grids, building automation, security and protection, smart home, remote health care etc.
The module's core processor is the ESP32,that is a single-chip solution that integrates dual-mode 2.4 GHz WiFi and Bluetooth in a smaller package size, using TSMC's ultra-low power 40-nanometer process with an integrated antenna switch , RF Balun, power amplifier, low noise amplifier, filter and power management module. ESP32 also integrates a wealth of peripherals, including capacitive touch sensors, Hall sensors, low-noise sense amplifier, SD card interface, Ethernet interface, high-speed SDIO / SPI, UART, I2S and I2C.
ESP32 chip integrates traditional Bluetooth, Bluetooth low energy and Wi-Fi, has a wide range of uses: Wi-Fi supports a wide range of communication connections, also supports direct connection to the Internet through a router; and Bluetooth allows users to connect mobile phones or broadcast BLE Beacon for signal detection. ESP32 chip sleep current less than 5μA, making it suitable for battery-powered wearable electronic devices. ESP32's operating system is freeRTOS with LWIP, and built-in TLS 1.2 with hardware acceleration. The chip also supports OTA encryption upgrade, developers can continue to upgrade after the release of the product.
