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.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch2 id=\"integrated-wireless-and-motion-sensing\" class=\"ng-star-inserted\"\u003e\u003cspan class=\"ng-star-inserted\"\u003eIntegrated Wireless and Motion Sensing\u003c\/span\u003e\u003c\/h2\u003e\n\u003cp class=\"ng-star-inserted\"\u003e\u003cspan class=\"ng-star-inserted\"\u003eThe 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.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3 id=\"technician-tip\" class=\"ng-star-inserted\"\u003e\u003cspan class=\"ng-star-inserted\"\u003eTechnician Tip\u003c\/span\u003e\u003c\/h3\u003e\n\u003cp class=\"ng-star-inserted\"\u003e\u003cspan class=\"ng-star-inserted\"\u003eAlways 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.\u003c\/span\u003e\u003c\/p\u003e","brand":"Waveshare","offers":[{"title":"Default Title","offer_id":68297698082967,"sku":"21CU000092","price":199.0,"currency_code":"HKD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0440\/4022\/4919\/files\/esp32-s3-1-28-inch-round-lcd-top-down.jpg?v=1794207675","url":"https:\/\/scccltd.com\/products\/waveshare-esp32-s3-1-28-inch-round-touch-lcd-board","provider":"Sun Cheong Computer Company Limited","version":"1.0","type":"link"}
