This AtomS3R is a compact programmable controller built around the ESP32-S3 main controller. It has the ESP32-S3-PICO-1-N8R8 controller with built-in WiFi, 8MB of onboard FLASH, and 8MB of PSRAM. The colourful 0.85" IPS screen, paired with a programmable button beneath it, provides an interactive interface for a variety of tasks. It is made for easy expansion and flexibility, featuring a 5V to 3.3V power circuit, a built-in three-axis BMM150 geomagnetic sensor, and a six-axis BMI270 altitude sensor for improved motion and orientation tracking. It also has a Type-C connector for power and firmware downloads, along with an HY2.0-4P expansion port. For additional functionality, six GPIO and power pins are reserved at the bottom. Compared to its predecessors, the AtomS3R has an improved 3D antenna, providing better signal performance and stability. Despite its small size of just 24 x 24 x 12.9mm, this controller packs a lot of power and is ideal for a wide range of projects. If you don't need a screen and would prefer a proto-board version.
