M5Stack ATOM Lite ESP32 Pico Development Kit

The M5Stack ATOM Lite is a highly compact (24 x 24 mm) IoT development board based on the ESP32-PICO-D4 system-on-chip. It features a dual-core processor running at 240 MHz, 520 KB of SRAM, and 4 MB of SPI flash memory. The board includes an integrated 3D antenna for robust 2.4 GHz Wi-Fi connectivity.

Designed for rapid prototyping and embedded projects, the ATOM Lite offers accessible GPIO pins via female HY2.0 connectors (2.54mm pitch) and a Grove interface (I2C/I/O/UART). It also features an onboard USB Type-C port for power and programming, alongside a programmable SK6812 RGB LED, a customizable button, and an IR transmitter.
