Adafruit Trinket M0 - for use with CircuitPython & Arduino IDE
➤ Same size, form-factor, and pinout as classic Trinket
➤ Updating ATtiny85 8-bit AVR for ATSAMD21E18 32-bit Cortex M0+
➤ 256KB Flash - 32x as much as 8 KB on ATtiny85
➤ 32 KB RAM - 64x as much as 512 bytes on ATtiny85
➤ 48 MHz 32 bit processor - 6x as fast as ATtiny85 (not even taking into account 32-bit speedups)
➤ 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. (ATtiny85 does not have native USB)
➤ Can be used with Arduino IDE or CircuitPython
➤ Built-in green ON LED
➤ Built in red pin #13 LED
➤ Built-in RGB DotStar LED
➤ All 5 GPIO pins are available and are not shared with USB - so you can use them for whatever you like!
➤ Five GPIO pins with digital input/output with internally connected pull-ups or pulldowns
➤ Three of the I/O pins can be used for 12-bit analog input
➤ True analog output on one I/O pin - can be used to play 10-bit quality audio clips in Arduino (CircuitPython does not have storage for audio clips)
➤ We gave the M0 pads the exact same names as the original Trinket so all your existing Arduino code will work exactly the same as-is without changes
➤ Two high-speed PWM outputs - for servos, LEDs, etc
➤ Three pins can also be used as hardware capacitive touch sensors with no additional components required
➤ Can drive NeoPixels or DotStars on any pins, with enough memory to drive 8000+ pixels.
➤ DMA-NeoPixel support on one pin so you can drive pixels without having to spend any processor time on it.
➤ Native hardware SPI, I2C and Serial available on two pads so you can connect to any I2C or Serial device with true hardware support (no annoying bit-banging). You can have either one SPI device or both I2C and Serial.
➤ Same Reset switch for starting your project code over
➤ Power with either USB or external output (such as a battery) - it'll automatically switch over
➤ 27mm x 15.3mm x 2.75mm / 1.07" x 0.6" x 0.1"
➤ Height with MicroUSB: 3.5mm / 0.14"
➤ Weight: 1.4g
