Product Description


CJMCU-871 PWM Speed Controller 3-30V/10A DC Motor Controller Single-Pass Digital Isolator


 


 


ESP-WROOM-32The module is a universal WiFi-BT-BLE MCU module that is powerful and versatile, and can be used in low-power sensor networks and extremely demanding tasks such as voice coding, audio streaming and MP3 decoding. The core of this module is the ESP32 chip, which is scalable and adaptive. Both CPU cores can be individually controlled or powered up. The clock frequency can be adjusted from 80 MHz to 240 MHz. The user can power off the CPU and use a low-power coprocessor to constantly monitor the state change of the peripheral or whether certain analogs exceed the threshold. The ESP-WROOM-32 module also integrates a wide range of peripherals including capacitive touch sensors, Hall sensors, low noise sense amplifiers, SD card interfaces, Ethernet interfaces, high speed SDIO/SPI, UART, I2S and I2C. . ESP-WROOM-32 module Hereinafter referred to as ESP32.


 


ESP-32Integrated with traditional wireless BLE, low-power wireless BLE and Wi-Fi, it has a wide range of uses: Wi-Fi supports a wide range of communication connections, and also supports direct connection to the Internet via a router; wireless BLE allows users to connect to a mobile phone or broadcast a BLE Beacon. For signal detection. The ESP32 chip's sleep current is less than 5uA, making it suitable for battery-powered wearable electronic devices. The ESP-32 supports data transfer rates of up to 150 Mbps, and with a power amplifier, the output power can reach 22 dBm, enabling ZUI's wide range of wireless communications. Therefore, this chip has industry-leading technical specifications, and has a good performance in terms of high integration, wireless transmission distance, power consumption, and network connectivity. The ESP32 operating system is a freeRTOS with LWIP and also has built-in TLS 1.2 with hardware acceleration. The chip also supports OTA encryption upgrades, developers can continue to upgrade after the product is released.
