Waveshare ESP32-S3-Tiny Board is an ESP32-S3-powered development board in a 23.50 x 18 mm from factor. What makes this board different from the Waveshare RP2040-Tiny is that it features 34 multi-function GPIO pins compared to 23 found on the RP2040-Tiny board.

On the board, you have an ESP32 chip, an LDO, an FPC Connector, a WS2812B RGB LED, and a 3D chip antenna. You will not find any USB to UART convert on the board because it gets connected to the board via the onboard FPC connector, this unique approach saves cost and time. Additionally, it has Wi-Fi, BLE, SPI, I2C, UART, ADC, PWM, and more.

You can buy either the ESP32-S3-Tiny or the ESP32-S3-Tiny-Kit with the USB-C board directly from Waveshare’s website. If you’re developing a product, you might start with a kit and later order individual MCU boards as needed.

The board is compact, and the inclusion of the ESP32-S3 makes it an ideal choice for IIoT applications. For those looking to get started with the board, the company provides detailed onboard parts lists to help you get started.

Adapting USB Type-C Port Via Adapter Board with FPC Cable

This compact board measures a mere 23.5 x 18mm with a slim 2.45mm thickness. Its versatile 2.54mm pin pitch wraps around three sides, making it easy to integrate into your projects. You have excellent programming flexibility with support for ESP-IDF, Arduino IDE, and MicroPython. To get started, you’ll find all the necessary documentation (including pinout diagrams, installation guides, and resource links) conveniently located on the board’s wiki page.

 

The board is cleverly designed to add more I/O within its compact form factor. Waveshare has added solderable pads just beside the pins of the dev board, increasing the I/O pin count to 34.

Waveshare’s ESP32-S3-Tiny board is available for purchase on a few different platforms. You’ll find both the standalone board and the ESP32-S3 Tiny-Kit on Amazon for $11.49 and $12.49 (with shipping included). If you’re looking to save a little, try checking Aliexpress or shopping directly from the Waveshare store, where prices begin at a budget-friendly $4.99 that of course does not include shipping.
