2 PACK ESP32 Development Board with 2.8 Inch Smart Display for Arduino

Specifications:

The ESP32-24325028 development board is based on the ESP32-D0WDQ6 controller, featuring a working voltage of 4.75-5.25V. It comes with a default SPI Flash of 32Mbit and internal RAM of 520KB. The board supports Wi-Fi 802.11b/g/n/e/i and Bluetooth 4.2BR/EDR and BLE standard.

It includes support interfaces such as UART, SPI, I2C, PWM, and TF card (maximum 4G). With 9 GPIO ports and a default serial port rate of 115200bps, the board operates within a spectrum range of 2400 ~ 2483.5MHz. It also features an onboard PCB antenna with a gain of 2dBi.

The image output format supported includes JPEG (only OV2640 supports), BMP, and GRAYSCALE. The packaging method is DIP-16, with a transmit power range of 802.11b: 17 ± 2dBm (@11Mbps), 802.11g: 14 ± 2dBm (@54Mbps), and 802.11n: 13 ± 2dBm (@MCS7).

The receiving sensitivity ranges from CCK, 1Mbps: -90dBm to MCS7 (65Mbps, 72.2Mbps): -67dBm. Power consumption varies from 180mA@5V when the flash is off to 310mA@5V when the flash is on and brightness is adjusted to the maximum.

The board also features deep-sleep mode (6mA@5V), moderm-sleep mode (20mA@5V), and light-sleep mode (6.7mA@5V). Security protocols supported include WPA/WPA2/WPA2-Enterprise/WPS, with a working temperature range of -20 ℃~ 70 ℃ and storage environment range of -40 ℃~ 125 ℃.

The display screen is controllable and can be used for APP remote control, remote environmental data collection, remote parameter setting, and other batch development applications.

Application areas for the ESP32-24325028 development board include home smart device image transmission, wireless monitoring, smart agriculture QR wireless recognition, wireless positioning system signal, and other IoT applications.

The board supports various functionalities such as UART/SPI/I2C/PWM/ADC/DAC interfaces, OV2640 and OV7670 cameras, built-in flash, picture WiFI upload, TF card support, multiple sleep modes, Embedded Lwip and FreeRTOS, STA/AP/STA+AP working mode, Smart Config, and AirKiss one-click network configuration for secondary development.
