Here comes the Adafruit Grand Central with the Microchip ATSAMD51.
The 120 MHz Cortex M4 with floating point support ensures a lot of speed and can be used in a variety of ways with a number of additional peripheral devices to support it.

The Grand Central is the first SAMD board that has enough pins in the form of the Arduino Mega / Due - with an enormous number of pins, analog inputs, two DAC outputs, 8 MByte QSPI flash,SD card socket and a NeoPixel.

Cortex M4 chip with 120 MHz
Floating point support with Cortex M4 DSP instructions
1 MB Flash, 256 KB RAM
32-bit, 3.3V logic and power supply
A total of 70 GPIO pins
Dual 1 MSPS DAC (A0 and A1)
Dual 1 MSPS ADC (15 analog pins)
8 x hardware SERCOM (can be I2C, SPI or UART)
22 x PWM outputs
Stereo I2S input / output with MCK pin
12-bit parallel capture controller (for camera / video input)
Built-in crypto engines with AES (256 bit), real RNG, pubkey Controller

Supply the Grand Central with 6-12 V polarity protected direct current or via the Mthe micro-USB connection with any 5V USB source. There is an on / off switch next to the 2.1mm DC jack that you can use to turn off your setup with ease. The card automatically switches between USB and DC.
Grand Central has 62 GPIO pins, 16 of which are analog and two of which are analog analog.
There is a hardware SPI port, a hardware I2C port and a hardware UART.
5 more SERCOMs are available for additional I2C / SPI / UARTs.
The logic level is 3.3 V.
Native USB, no hardware USB-to-serial converter is required as the Metro M4 has built-in USB support. When used as a serial device, the USB interface can be used by any Coused by every computer to receive / send data to METRO. It can also be used to launch and update code through the boot loader. It can also act like a hidden keyboard or mouse.
Four indicator LEDs and a NeoPixel on the front edge of the board for easy debugging.
A green power LED, two RX / TX LEDs for data sent via USB and a red LED are connected. Next to the reset button there is an RGB NeoPixel that can be used for any purpose.
8 MB QSPI flash memory chip are included on board. You can use the SPI flash memory like a very small hard drive. When used in Circuit Python, the 8MB flash acts as the Sas storage for all of your scripts, libraries and files. When used in Arduino you can read / write files like a small data logger or SD card and then access the files via USB using our utility.
Micro SD Card Slot - removable storage of any size, connected to a SPI SERCOM (SDIO is not supported)
The simple reprogramming is pre-installed with the UF2 bootloader, which looks like a USB storage key. Just pull out the firmware to program, no special tools or drivers are required! It can be used to load CircuitPython or Arduino IDE (it''s Bossa v1.8 compatible)
