C126 ATOMS3R development kit with 0.85-inch display (8 MB PSRAM)

AtomS3R is a highly integrated, programmable IoT controller based on the ESP32-S3. It uses the ESP32-S3-PICO-1-N8R8 SoC with integrated Wi-Fi, 8 MB of flash memory, and 8 MB of PSRAM. The device features a 0.85-inch color IPS display with a programmable button below it, an integrated 5 V to 3.3 V power supply, a three-axis BMM150 geomagnetic sensor, and a six-axis BMI270 IMU (Inertial Measurement Unit).

Power is supplied and firmware updates are performed via a USB Type-C port, while a HY2.0-4P port and six GPIO and power pins on the bottom allow for easy expansion. Compared to previous models, the AtomS3R is equipped with an improved 3D antenna that offers better performance and greater stability. With compact dimensions of 24.0 x 24.0 x 12.9 mm, it is ideally suited for a wide variety of embedded smart device applications.
