AtomS3 Lite Programmable Controller
Build compact IoT and embedded projects with a programmable controller that combines Wi-Fi, expandable interfaces, and USB download support.
✅ Connect your smart device projects wirelessly with integrated Wi-Fi for IoT nodes and embedded applications.
✅ Prototype faster with a USB Type-C download and serial connection for program loading and debugging.
✅ Expand your builds with 6 GPIO headers and GROVE/HY2.0-4P interfaces for flexible connections.
✅ Fit the controller into compact designs thanks to its 24 mm × 24 mm × 9.5 mm size and 5.3 g weight.
✅ Mount it securely in your project using the M2 screw hole for fixing.
✅ See status at a glance with RGB indicators and use the programmable button for control inputs.
Made for Arduino and UIFlow development
The AtomS3 Lite is based on the ESP32-S3FN8 and includes 8MB SPI flash memory for embedded development tasks.
Its built-in 3D antenna, infrared emission function, and Type-C power supply mode make it a practical choice for smart device prototypes.
