Simplified ESP-WROOM-32 Development Board for Arduino Users

Feature: 1. The ESP-WROOM-32 development board is the module, and the parameter characteristic of the ESP-WROOM32 is also the parameter characteristic of the module. 2. The module has a low-power dual-core 32-bit CPU that can be used as an application processor. 3. The module supports UART, SPI, I2C, PWM, DAC, ADC, and other interfaces. 4. The module supports the openOCD debugging interface. 5. The module supports multiple sleep modes, with a current of 6.5μA in deep sleep. 6. The module embeds LwIP and FreeRTOS. 7. The module supports STA/AP/STA+AP mode. 8. The module supports Smart Config / Airkiss one-key network distribution. 9. The module supports general AT commands, making it easy to use. 10. The module supports local serial port upgrade and remote upgrade (FOTA).

Specification: The default SPI flash is 32Mbit. The supported interfaces include UART, SPI, SDIO, I2C, PWM, I2S, IR, ADC, and DAC. The on-chip sensors include a Hall sensor, temperature sensor, and capacitive touch sensor. The module has 22 I/O ports and a power consumption of 300mA at 3.3V. The security features include WPA/WPA2/WPA2 Enterprise/WPS. The power supply range is 5.0V to 12V, and the working temperature is -20°C to 85°C. The storage environment temperature is -40°C to 90°C. The product size is 52 × 29 × 15mm / 2.04 × 1.14 × 0.59 inches.

The main body of the module is the ESP-WROOM-32 module, and the peripheral uses the USB serial port chip CP2102 to expand the micro USB interface, allowing direct debugging by a USB-connected computer with fast and stable data transmission. The module has a power indicator (red light) and a working status indicator (blue light), so you can always know the status of the module.

There are two touch buttons: one is for reset, and the other is for enabling the module to enter the halberd program mode. The pins on both sides of the development board are convenient for developers to connect and use.

The ESP-32 dual-mode module is compact and easy to embed into your device, making it convenient for you to use. It is compatible with the Arduino IDE, and it also supports NodeMCU and other development environments, expanding the range of available resources and greatly improving the ease of learning and development. Of course, it can also be widely used in Internet of Things applications.
