Brand new, unopened. Purchased from Digikey. No longer needed for our boards.
- ATSAMD21G18 32-bit Cortex M0+ with 256KB Flash and 32 KB RAM
- 3.3V logic, 48 MHz, 32 bit processor
- 2 MB SPI FLASH chip for storing files and CircuitPython code storage.
- 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
- Tons of GPIO! 23 x GPIO pins with following capabilities:
- 1 x True analog output pin – can be used to play 10-bit quality audio clips
- 13 x PWM outputs – for servos, LEDs, etc
- 11 x 12-bit analog inputs
- 7 x Hardware capacitive touch sensors with no additional components required
- 1 x Special Vhigh output pin gives you the higher voltage from VBAT or VUSB, for driving NeoPixels, servos, and other high-current 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 8000+ pixels. DMA-NeoPixel support on the VHigh pin so you can drive pixels without having to spend any processor time on it.
- Native hardware SPI, I2C and Serial all available
- Reset button and pin
- Power with either USB or external output (such as a battery) – it’ll automatically switch over
