Description

Waveshare ESP32-S3-Tiny-Kit is a compact ESP32-S3 development board built around the ESP32-S3FH4R2 dual-core processor. This kit version includes the ultra-small main board, the USB Type-C adapter board, and the FPC cable, making development more convenient while keeping the core board thin and easy to embed. With 2.4GHz Wi-Fi, Bluetooth LE, 34 multi-function GPIOs, and support for ESP-IDF, Arduino, and MicroPython, it is a practical choice for compact wireless controllers, AIoT nodes, and custom embedded products.

Features

• ESP32-S3FH4R2 processor: Xtensa 32-bit LX7 dual-core processor with up to 240MHz main frequency for compact wireless and AIoT applications.
• Wireless connectivity: Integrated 2.4GHz Wi-Fi and Bluetooth LE with solid RF performance for connected embedded devices.
• Compact split design: The main board and USB/button section are separated, helping reduce board thickness and making the module easier to integrate into products.
• 34 multi-function GPIOs: Rich peripheral expansion for SPI, I2C, UART, ADC, and PWM development.
• Kit version for faster setup: Includes the adapter board and FPC cable, so you can quickly access USB Type-C power and programming.
• Flexible software support: Official support for ESP-IDF, Arduino IDE, and MicroPython.

Specifications

Applications

FAQ

What is included in this kit version?

This version includes the ESP32-S3-Tiny main board, the adapter board, and the FPC cable. It is more convenient than the board-only version if you want immediate USB Type-C access for flashing and testing.

What is the difference between this board and the N8R8 version?

This model uses the ESP32-S3FH4R2 with 4MB Flash and 2MB PSRAM. The ESP32-S3-Tiny-N8R8 version provides 8MB Flash and 8MB PSRAM for applications that need more memory.

Which development environments are supported?

Official documentation covers ESP-IDF, Arduino IDE, and MicroPython, so you can choose the toolchain that best fits your workflow.
