Adafruit Metro M4 Express AirLift Lite ESP32 Coprocessor

Adafruit Metro M4 Express AirLift Lite ESP32 Coprocessor adds wireless capabilities to the Metro M4 development board. With pre-loaded root certificates, the certified Wi-Fi® module can handle Transport Layer Security and socket needs. The device is powered by the Microchip ATSAMD51 and a Cortex M4 core processor running at 120MHz. The Airlift can power the Metro M4 with 7V to 9V polarity-protected direct current or a micro-USB connector to any 5V USB source. The Airlift can also load CircuitPython or Arduino IDE libraries for use in wireless integration and in building Internet of Things (IoT) projects.
