ESP-WROOM-32 is a general-purpose WiFi-BT-BLE MCU module with powerful functions and a wide range of uses.
The core of this module is the ESP32 chip, which is scalable and adaptive.
The two CPU cores can be controlled or powered up independently.
The clock frequency can be adjusted from 80 MHz to 240 MHz.
The user can cut off the power to the CPU and use the low-power coprocessor to constantly monitor the state changes of peripherals or whether certain analog quantities exceed thresholds.
ESP32 also integrates a wealth of peripherals, including capacitive touch sensors, Hall sensors, low-noise sense amplifiers, SD card interface, Ethernet interface, high-speed SDIO/SPI, UART, I2S, and I2C, etc.
ESP-WROOM-32 integrates traditional Bluetooth, low-energy Bluetooth, 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;
while Bluetooth allows users to connect mobile phones Or broadcast BLE Beacon for easy signal detection.
The sleep current of the ESP32 chip is less than 5mA, making it suitable for battery-powered wearable electronics.
The ESP-WROOM-32 supports a data transfer rate up to 150 Mbps,
and after passing through the power amplifier, the output power can reach 22 dBm,
which can realize wireless communication in a wide range.
Therefore, this chip has leading technical specifications and has good performance in terms of high integration, wireless transmission distance, power consumption, and network connectivity.
The operating system of the ESP32 is freeRTOS with LWIP and also has built-in TLS 1.2 with hardware acceleration.
The chip also supports OTA encryption upgrade, and developers can continue to upgrade after the product is released.
