ESP32 Development Board TYPE-C MICRO USB CH340C WiFi+Bluetooth Ultra-Low Power Consumption Dual Core ESP32-DevKitC-32 ESP-WROOM Introduction: Development board model: ESP32-DevKitC-32 Module model: ESP32-WROOM-32 Main control chip: ESP32-DOWDQ6-V3 dual-core 32bit MCU integrated WiFi, Bluetooth, Integrated 520-kBSRAM, 448-kBROM16-kBSRAMinRTC External storage: 4MB USB driver chip: CH340C, with good system compatibility, higher download speed, and more stability. Support VIN external wide voltage input 5-12V power supply (battery version maximum 5.5V input) Support USB power supply, external 3.3V power supply, and VIN power supply three kinds of power supply Mode development board size: 52*28mm/weight about 9.5g Support ArduinoIDE mixly, mind+, Python and other programming software Description: 1. The main body of the module is ESP-WROOM-32 module, and the peripheral uses the USB serial port chip CP2102 to expand the micro USB interface, which can be directly debugged by a USB connected computer, and the data transmission is fast and stable. 2. It has power indicator (red light) and working status indicator (blue light) on it, so you can know the status of the module at any time. 3. There are two touch buttons, one is reset, the other is enable module to enter the halberd program mode. In addition, the pins on both sides of the development board are convenient for developers to connect and use. 4. The module has powerful Bluetooth-compatible and WiFi functions. As a Bluetooth-compatible and WiFi development board, it can obtain rich resources from Lexin and anxinco websites. 5. In addition, the module supports for NodeMCU and other development environments, which expands the range of its resources available and greatly improves the ease of learning and development. Of course, it can also be widely used in Internet of things occasions, such as home automation, wireless industrial control, wireless positioning system signal, etc. Feature: 1. The module is the ESP- WROOM-32 development board, and the ESP- WROOM32 parameter characteristic is also the parameter characteristic of the module. 2. 802.11b/g/WiFi + BT module. 3. Low power dual core 32-bit CPU, which can be used as application processor; 4. The main frequency is up to 240MHz, and the operation capacity is up to 600DMIPS. 5. Support UART / SPI / I2C / PWM / DAC / ADC and other interfaces; 6. Support openOCD debugging interface; 7. It supports multiple sleep modes, and the current reaches 6.5ua in deep sleep; 8. Embedded LwIP and FreeRTOS; 9. Support STA/AP/STA+AP mode; 10. Support Smart Config / Airkiss one key distribution network; 11. General at command, easy to use; 12.
