Adafruit Metro M4 Express AirLift (WiFi) - Lite

Elevate your next project with the Adafruit Metro M4 AirLift—a powerful microcontroller board that combines the speed and capabilities of the ATSAMD51 with the wireless power of the ESP32 co-processor. This versatile board offers all the features you love about the Metro M4, with added WiFi connectivity for easy IoT integration, making it ideal for wireless projects.

Key Features:

• ATSAMD51 Microcontroller:
  • 120 MHz Cortex-M4 core with floating-point support.
  • 512 KB Flash, 192 KB RAM for fast and spacious performance.
  • Built-in crypto engines with AES (256-bit encryption), true RNG, and Pubkey controller.
• AirLift WiFi Co-processor:
  • Certified WiFi module with TLS/SSL support, pre-loaded root certificates.
  • Communication via SPI and ready-to-use Arduino and CircuitPython libraries for quick wireless integration.
• Dual Analog/Digital Conversion:
  • 2 x 1 MSPS DAC and 2 x 1 MSPS ADC for precise analog signal processing.
  • Stereo I2S input/output with MCK pin for audio.
• Expanded I/O:
