AtomS3R

SKU:C126

Description

AtomS3R is a highly integrated IoT programmable controller based on the ESP32-S3 main control. It integrates the ESP32-S3-PICO-1-N8R8 main control, with built-in Wi-Fi functionality, 8 MB on-chip Flash, and 8 MB PSRAM; equipped with a 0.85-inch color IPS screen, with a programmable button below the screen; includes a 5V to 3.3V circuit; built-in three-axis BMM150 geomagnetic sensor and six-axis BMI270 attitude sensor; features a USB Type-C interface for power supply and firmware download; includes a HY2.0-4P expansion port; has six GPIO and power pins at the bottom for expansion. Compared to previous products, the 3D antenna of AtomS3R has been enhanced, providing better performance and higher stability. The product dimensions are only 24.0 x 24.0 x 12.9mm, suitable for various embedded smart device applications.

BMM150 Magnetic Field Interference

Products with magnets may interfere with the BMM150 magnetic field sensor, causing abnormal readings. When used with an M5 master control device containing a magnet, the magnet needs to be removed, and at the same time, the BMM150 sensor should be kept away from strong magnetic fields.

Download Mode

To flash firmware, press and hold the reset button (about 2 seconds) until the internal green LED lights up, then release. The device is now in download mode, ready for flashing.

Note

When controlling the LCD backlight, it is recommended to use a PWM frequency of 500Hz.
