ATOMS3R Development Kit with 0.85-inch Screen (8MB PSRAM)

Description

AtomS3R is a highly integrated IoT programmable controller based on the ESP32-S3. It embeds an ESP32-S3-PICO-1-N8R8 SoC with on-chip Wi-Fi, 8MB Flash, and 8MB PSRAM. The device features a 0.85-inch color IPS display with a programmable button beneath it, an on-board 5 V-to-3.3 V power circuit, a three-axis BMM150 geomagnetic sensor, and a six-axis BMI270 IMU. Power supply and firmware downloading are handled through a USB Type-C connector, while a HY2.0-4P port and six GPIO plus power pins on the bottom make expansion easy. Compared with previous products, AtomS3R is equipped with an enhanced 3D antenna that offers better performance and higher stability. With dimensions of just 24.0 x 24.0 x 12.9 mm, it is ideal for a variety of embedded smart-device applications.
