 This **Metro M0 Express** board looks a whole lot like the [original Metro 328](https://www.adafruit.com/product/2488), but with a huge upgrade. Instead of the ATmega328, this Metro features a ATSAMD21G18 chip, an ARM Cortex M0+. It's the first Adafruit Metro that is designed for use with CircuitPython! 
 
-At the Metro M0's heart is an ATSAMD21G18 ARM Cortex M0 processor, clocked at 48 MHz and at 3.3V logic, the same one used in the new [Arduino Zero](https://www.adafruit.com/products/2843). This chip has a whopping 256K of FLASH (8x more than the Atmega328) and 32K of RAM (16x as much)! This chip comes with built in USB so it has USB-to-Serial program & debug capability built in with no need for an FTDI-like chip.

-*   **Power the METRO** with 7-9V polarity protected DC or the micro USB connector to any 5V USB source. The 2.1mm DC jack has an on/off switch next to it so you can turn off your setup easily. The METRO will automagically switch between USB and DC.
-*   **METRO has 25 GPIO pins**, 12 of which are analog in, and one of which is a true analog out. There's a hardware SPI port, hardware I2C port and hardware UART. Logic level is 3.3V
-*   **Native USB**, there's no need for a hardware USB to Serial converter as the Metro M0 has built in USB support. When used to act like a serial device, the USB interface can be used by any computer to listen/send data to the METRO, and can also be used to launch and update code via the bootloader. It can also act like a keyboard, mouse or MIDI device as well.
-*   **Four indicator LEDs and one NeoPixel**, on the front edge of the PCB, for easy debugging. One green power LED, two RX/TX LEDs for data being sent over USB, and a red LED connected. Next to the reset button there is an RGB NeoPixel that can be used for any purpose.
-*   **2 MB SPI Flash **storage chip is included on board. You can use the SPI Flash storage like a very tiny hard drive. When used in Circuit Python, the 2 MB flash acts as storage for all your scripts, libraries and files.
-*   **Easy reprogramming**, comes pre-loaded with the [UF2 bootloader](https://learn.adafruit.com/adafruit-metro-m0-express-designed-for-circuitpython/uf2-bootloader), which looks like a USB storage key. Simply drag firmware on to program, no special tools or drivers needed! It can be used to load up CircuitPython, PXT/MakeCode or Arduino IDE (it is bossa-compatible)

 Give your next project a lift with _AirLift_ - Adafruit's witty name for the ESP32 co-processor that graces this Metro M4. 
 
-You already know about the **Adafruit Metro M4** featuring the **Microchip ATSAMD51**, with it's 120MHz Cortex M4 with floating point support. With a train-load of FLASH and RAM, your code will be fast and roomy. And what better way to improve it than to add wireless? Now cooked in directly on board, you get a certified WiFi module that can handle all your TLS and socket needs, it even has root certificates pre-loaded.

-This Metro is the same size as the others, and is compatible with all our shields. It's got analog pins where you expect, and SPI/UART/I2C hardware support in the same spot as the Metro 328 and M0\. But! It's powered with an ATSAMD51J19:
-
-*   Cortex M4 core running at **120 MHz**
-*   [Floating point support with Cortex M4 DSP instructions](https://developer.arm.com/technologies/dsp/dsp-for-cortex-m)
-*   **512 KB** flash, **192 KB** RAM
-*   32-bit, 3.3V logic and power
-*   Dual 1 MSPS DAC (A0 and A1)
-*   Dual 1 MSPS ADC (8 analog pins)
-*   6 x hardware SERCOM (I2C, SPI or UART)
-*   22 x PWM outputs
-*   Stereo I2S input/output with MCK pin
-*   10-bit Parallel capture controller (for camera/video in)
-*   Built in crypto engines with AES (256 bit), true RNG, Pubkey controller
-*   64 QFN
