M5Stack AtomS3 Lite
The M5Stack AtomS3 Lite is an ultra-compact development board based on the ESP32-S3 (ESP32-S3FN8) microcontroller. Measuring just 24x24mm, it packs serious capability into a tiny form factor — without a display, keeping costs down and power consumption minimal.
Key Features
- ESP32-S3 dual-core Xtensa LX7 processor at 240MHz
- 8MB Flash for ample firmware and data storage
- WiFi 802.11 b/g/n (2.4GHz) + Bluetooth LE 5.0
- Ultra-compact 24x24mm form factor
- Grove port for easy sensor and actuator connectivity
- USB-C for power and programming
- 1x RGB LED (WS2812) for status indication
- 1x Programmable button for user input
- 6x GPIO pins exposed for expansion
Design Philosophy
The AtomS3 Lite strips away the display found on the AtomS3, resulting in a lower-cost, lower-power variant that's ideal for headless IoT deployments. The Grove connector makes it easy to add sensors, displays, or other peripherals from the M5Stack ecosystem.
