Adafruit Grand Central M4 Express, SAMD51, without female headers

The Adafruit Grand Central not only delivers powerful 120 MHz with the Cortex M4 and its hardware floating point support, but also enough inputs and outputs and peripherals to be able to implement even the most demanding projects. Due to the many I/Os of the chipset, it was possible for Adafruit to bring a SAMD board in the form of the popular Arduino Mega for the first time. The board not only provides many inputs and outputs, but also a large number of analog inputs, two D/A converters, 8 MB GSPI flash memory, a MicroSD card slot and a NeoPixel LED.

This version is the cheaper version without soldered socket strips. If necessary, you can solder on the supplied 2.1mm DC socket. Socket or pin strips are not included in the scope of delivery.

Product features:

• 32-bit Cortex M4 with 120 MHz clock
• Hardware DSP and floating point support
• 1 MB flash memory, 256 KB RAM
• 32-bit, 3.3V logic level and operating voltage
• 70 GPIOs
• 2 x true analog output (A0 and A1)
• 15 x 12-bit analog inputs
• 8 x Hardware SERCOM - Native support of SPI, I2C, UART 
• 22 x PWM outputs - for LEDs and servos and much more
• Stereo I2S input and output
• Integrated crypto engine for 256 bit AES, RNG, pubkey
• 12-bit parallel capture controller for camera and video signals

The board also has the following product features:

• Native USB support by any operating system - can be used with the Arduino IDE or CircuitPython as a serial console, mouse/keyboard HID, and even as a small drive to store Python scripts.
• 4 indicator LEDs and a NeoPixel: Power, RX, TX and a red LED + RGB NeoPixel for free use.
• 8 MB QSPI flash memory for storing files or CircuitPython code.
• MicroSD card slot
• Comes with a pre-installed UF2 bootloader that masquerades as a USB storage medium on the computer. Firmware can thus be installed on the board without additional programs or adapters.
