ESP32-S3-Tiny

Product Overview​

The ESP32-S3-Tiny is a compact microcontroller development board equipped with multiple digital interfaces. The product adopts a split design, separating the USB and button circuits to reduce the overall thickness and size of the PCB board. It brings out 34 GPIOs in an extremely small form factor, making it easier for users to integrate into their projects. The split design, compact size, and very thin profile make this board ideal for projects requiring a small footprint.

Hardware-wise, it is built around the ESP32-S3 chip, which integrates a high‑performance Xtensa® 32‑bit LX7 dual‑core processor, an ultra‑low‑power coprocessor, Wi‑Fi baseband, Bluetooth baseband, RF module, and various peripherals. It can be expanded with a wide range of external devices for greater convenience.

On the software side, you can choose to develop in the ESP-IDF development environment or on the Arduino IDE, making it easy and quick to get started and apply it to products.

FPC Cable Installation​

warning

Please read this entire section and the precautions carefully before installing the FPC cable, otherwise it may cause device damage or short circuits!

warning
  • Do not plug or unplug the FPC cable while the device is powered, otherwise a short circuit may occur.
  • When installing the FPC cable, make sure it is centered and inserted all the way to the bottom. Incorrect installation may cause connection issues or even a short circuit.

  1. Open the FPC connector flap
