1. Using the ESP32-S3 chip, the chip integrates a high-performance Xtensa 32-bit LX7 dual-core processor with a main frequency of up to 240 MHz. 2. Integrated 512 KB , 384 KB ROM, 16 KB , 2MB PSRAM and 4MB Flash memory. 3. Integrated Bluetooth LE wireless communication and 2.4 GHz Wi-Fi, with superior radio frequency performance. 4. Using USB Type-C interface, there is no need to worry about plugging it forward and backward. 5. Introduce rich peripheral interfaces, which can realize various functions more flexibly. ESP32-S3-Tiny is a small microcontroller development board equipped with a of digital interfaces. The product adopts a split design, which can separate the USB and button circuits, reduce the overall thickness and volume of the PCB board, and introduce 34 GPIOs in a very small form factor, making it easier for users to integrate into projects. Split design, compact size and very thin thickness, making this board perfect for projects requiring small size. In terms of hardware, the ESP32-S3 chip is used, which integrates a high-performance Xtensa 32-bit LX7 dual-core processor, ultra-low-power co-processor, Wi-Fi baseband, Bluetooth baseband, RF module and peripherals. It can be compatible and expanded with a of peripheral devices, making it more convenient to use. In terms of software, you can choose the ESP-IDF development environment or develop on the for IDE, so you can get started easily and quickly and apply it to products. Supports multiple low-power working states, can adjust the balance between communication rate and power consumption, and meet the power consumption requirements of various application scenarios.
