Adafruit has today launched the new Adafruit Trinket M0 microcontroller board which has been designed to be used with both Arduino and the CircuitPython IDE.
The new microcontroller uses the same form factor as the original ATtiny85-based Trinket but now offers many more features thanks to the addition of a ATSAMD21E18 which has replaced the ATtiny85.
The Adafruit Trinket M0 is now available to purchase price $8.95 directly from the Adafruit online store. Specifications and features of the Adafruit Trinket M0 microcontroller board include :
◦ 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 pullups 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
▪ 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
◦ Mounting holes! Yeah!
◦ Really really small
