Here are some of the updates you can look forward to when using ItsyBitsy M4:

• Same size, form-factor as the ItsyBitsy 32u4 and ItsyBitsy M0, and nearly-identical pinout as both
• ATSAMD51 32-bit Cortex M4 core running at 120 MHz
• Hardware DSP and floating point support
• 512 KB flash, 192 KB RAM
• 2 MB SPI FLASH chip for storing files and CircuitPython code storage.
• 32-bit, 3.3V logic and power
• Tons of GPIO! 23 x GPIO pins with following capabilities:
  • Dual 1 MSPS 12 bit true analog DAC (A0 and A1) - can be used to play 12-bit stereo audio clips
  • Dual 1 MSPS 12 bit ADC (7 analog pins some on ADC1 and some on ADC2)
  • 6 x hardware SERCOM - Native hardware SPI, I2C and Serial all available
  • 18 x PWM outputs - for servos, LEDs, etc
  • No I2S. We have no idea why but I2S is only supported on the 64 pin version of this chip and we could only fit the 48 pin version. But there's a stereo DAC you could use?
  • 8-bit Parallel capture controller (for camera/video in)
  • 1 x Special Vhigh output pin gives you the higher voltage from VBAT or VUSB, for driving NeoPixels, servos, and other 5V-logic devices. Digital 5 level-shifted output for high-voltage logic level output.
  • Can drive NeoPixels or DotStars on any pins, with enough memory to drive 60,000+ pixels. DMA-NeoPixel support on the VHigh pin so you can drive pixels without having to spend any processor time on it.
• Built in crypto engines with AES (256 bit), true RNG, Pubkey controller
• Native USB supported by every OS - can be used in Arduino or CircuitPython as USB serial console, Keyboard/Mouse HID, even a little disk drive for storing Python scripts.
• Can be used with Arduino IDE or CircuitPython
• Built in red pin #13 LED
• Built in RGB DotStar LED
• Reset button and pin
• Power with either USB or external output (such as a battery) - it'll automatically switch over
• Comes pre-loaded with the 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 or Arduino IDE (it is bossa v1.8 compatible)

Each order comes with one assembled and tested ItsyBitsy M4, with headers that can be soldered in for use with a breadboard. ItsyBitsy M4 comes with CircuitPython programmed in, but you can replace the code with Arduino if you like.
