The M5Stack AtomS3R is the most integrated programmable controller on the market, based on the ESP32-S3 main controller. It features the ESP32-S3-PICO-1-N8R8 main controller with built-in WiFi, 8MB onboard FLASH, and 8MB PSRAM. M5Stack AtomS3R comes with a 0.85-inch color IPS screen and a programmable button beneath it. AtomS3R includes a 5V to 3.3V power circuit, a built-in three-axis BMM150 geomagnetic sensor, and a six-axis BMI270 attitude sensor. AtomS3R also has a Type-C interface for power supply and firmware downloads, along with a HY2.0-4P expansion port. Six GPIO and power pins are reserved at the bottom for easy expansion. The 3D antenna of the M5Stack AtomS3R is an improvement on previous products, offering better performance and greater stability. M5Stack AtomS3R measures only 24x24x12.9mm, making it ideal for a wide range of embedded smart device applications.
