Product-specific buyer note

Confirm PID 4064 rather than the no-header PID 4084 and retain Evelta's invoice for its 14-day replacement window. This board is commercially distinct from the catalogued Feather M4 through its Mega footprint, 62 GPIO, microSD and power architecture. Check shield voltage and pin compatibility individually; Mega shape does not make old 5 V shields electrically safe.

India regulatory note

Treat this as an ESD-sensitive bare board. All digital logic is 3.3 V; level-shift incompatible 5 V signals and verify external-supply polarity before connection. Disconnect power before changing wiring, update old UF2 bootloaders where Adafruit advises, fuse high-current loads separately and never drive mains or motors directly from GPIO.

Specifications

Use these captured specifications to match the exact model and variant on the seller page.

model identity: Adafruit Grand Central M4 Express PID 4064 with headers and DC jack; not PID 4084 without headers
processor: Microchip ATSAMD51P20A 32-bit Cortex-M4F at 120 MHz with hardware DSP and floating point
memory: 1 MB internal flash and 256 KB SRAM
logic: 3.3 V logic and power; GPIO inputs are not 5 V tolerant
io: 70 MCU pins exposed across the design, with 62 usable GPIO and 22 PWM outputs described in the guide
analogue: Sixteen analogue-capable inputs and two independent 12-bit DAC outputs; ADC/DAC up to 1 MSPS subject to code and mode
serial: Eight hardware SERCOM blocks configurable across I2C, SPI and UART
storage: 8 MB QSPI flash plus microSD slot on an SPI SERCOM; SDIO is not supported
usb and boot: Native USB supporting serial/HID roles and drag-and-drop UF2 bootloader updates
software: CircuitPython primary support plus Arduino IDE board package
form factor: Arduino Mega shape and shield layout with common Metro-compatible front-half pinout
power: Micro-USB 5 V or polarity-protected 6-12 V centre-positive 2.1 mm DC jack with on/off switch
physical: Approximately 101.6 x 53.3 x 15.3 mm and 35 g

Product context

Common use cases

Large-I/O robotics, lighting or control prototypes that outgrow smaller Feather-class boards
CircuitPython data loggers using onboard QSPI and removable microSD storage
Arduino Mega-shape educational systems needing multiple UART, SPI, I2C, PWM and analogue channels
