  • ESP32-S3 Dual-Core Processor: Runs up to 240MHz with 2MB PSRAM and 16MB Flash for smooth UI performance and multitasking.
  • Wireless Connectivity: Integrated 2.4GHz Wi-Fi and Bluetooth 5 (BLE) for reliable IoT communication.
  • 6-Axis IMU Sensor: Onboard QMI8658 tracks acceleration and gyroscope data for motion gestures and step counting.
  • Portable Power Ready: Includes an MX1.25 battery header and ETA6096 manager for safe 3.7V lithium battery charging and discharging.

Full Product Description

Compact Hardware for Wearable Development

This development board provides a complete hardware foundation for building custom smartwatches and wearable IoT devices. The centerpiece is a vibrant 1.28-inch round IPS display (240x240 resolution) driven by the GC9A01 controller, paired with a CST816S capacitive touch chip for smooth, responsive human-machine interaction. The compact circular footprint makes it easy to integrate into 3D-printed watch cases or custom dashboard gauges.

Integrated Wireless and Motion Sensing

The built-in ESP32-S3 chip delivers reliable 2.4GHz Wi-Fi and Bluetooth 5 (BLE) connectivity for seamless IoT data syncing and smartphone communication. To support fitness tracking and gesture recognition, the board is equipped with a QMI8658 6-axis IMU, which includes a 3-axis gyroscope and a 3-axis accelerometer. With 2MB of onboard PSRAM and 16MB of Flash, it easily handles complex graphical user interfaces (GUIs) and sensor data processing simultaneously.

Technician Tip

Always double-check the polarity of your 3.7V lithium battery before connecting it to the onboard MX1.25 header. The ETA6096 chip safely manages battery charging via the Type-C port, but reverse polarity will instantly damage the power management circuit. Our Sun Cheong Computer Co. Ltd. technical team recommends using an SH1.0 connector cable to easily break out the 6 available GPIO pins (15, 16, 17, 18, 21, 33) for external sensors, rather than attempting to solder directly to the tiny surface-mount pads.

FAQ Section

  • Can I program this board using the Arduino IDE?Yes, the ESP32-S3 chip is fully compatible with the Arduino IDE, as well as Espressif's official ESP-IDF framework for more advanced development.
  • Does this board include a lithium battery?No, the board features an MX1.25 header and an ETA6096 charging manager for a 3.7V lithium battery, but the battery itself is not included.
  • How do I access the GPIO pins for external sensors?You can access 6 GPIO pins (15, 16, 17, 18, 21, 33) along with 3V3 and GND via the SH1.0 connector located on the back of the board.
  • What display drivers do I need to select in my code?You must configure your graphics library (such as LVGL or TFT_eSPI) to use the GC9A01 driver for the display and the CST816S driver for the capacitive touch input.
  • Can I buy compatible 3.7V lithium batteries at your Sham Shui Po store?Yes, we stock various small-capacity 3.7V lithium polymer batteries with MX1.25 connectors at our Sham Shui Po retail shop, perfect for wearable projects.
