Product description: AtomS3R Ext Proto Kit - development module with breadboard - M5Stack C126-Ext
AtomS3R-Ext is a modern development platform designed for embedded system designers and IoT solution creators. Its heart is the efficient ESP32-S3-PICO-1-N8R8 system with a dual-core Xtensa LX7 processor, clocked at up to 240 MHz , supported by 8 MB of Flash memory and 8 MB of PSRAM. On the top of the housing there is a universal prototyping board that allows you to quickly connect and test many GPIO pins. Thanks to the built-in nine-axis IMU (BMI270 + BMM150) , the module is ideal for projects requiring precise motion tracking and spatial orientation. AtomS3R-Ext supports IR transmission, allows easy expansion thanks to the Grove port and provides fast data transfer and power supply via the USB Type-C port. The 3D antenna provides better range and stability of the WiFi connection compared to previous models from the Atom series .
