SKU:K001-V26












Basic v2.6 is a cost-effective IoT entry-level main controller. It uses the Espressif ESP32 chip, equipped with 2 low-power Xtensa® 32-bit LX6 microprocessors, with a main frequency of up to 240 MHz. It has onboard 16MB Flash memory, integrated 2.0-inch full-color high-definition IPS display panel, speaker, TFCard slot, and other peripherals. The full-cover shell ensures the stability of circuit operation even in complex industrial application scenarios. The internal bus provides a variety of commonly used interface resources (ADC/DAC/I2C/UART/SPI, etc.), with 15 x IO leads on the bottom bus, offering strong expandability. It is suitable for various product prototype development, industrial control, and smart building application scenarios.
