Adafruit has today announced the availability of the new Adafruit GEMMA M0 miniature wearable electronic platform priced at $9.95, which is both powerful and tiny and is now equipped with a ATSAMD21E18.
The GEMMA M0 can be programmed using the Arduino IDE and the new hardware comes with CircuitPython on board. No installs, IDE or compiler are required, so it can be connected to any computer you can’t install software on, even ChromeBooks if required.
Features of the new GEMMA M0 Miniature Wearable Development Board :
• Same size, form-factor, and pinout as classic Gemma
• Updating ATtiny85 8-bit AVR for ATSAMD21E18 32-bit Cortex M0+
• 256KB Flash – 8x 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 RGB DotStar LED
• Three big-hole sew-pads can be used for conductive thread or alligator-clips for fast prototyping
• Each I/O pad can be used for 12-bit analog input, or digital input/output with internally connected pullups or pulldowns
• We gave the M0 pads the exact same names as the original Gemma so all your existing Arduino code will work exactly the same as-is without changes
• True analog output on one I/O pad – can be used to play 10-bit quality audio clips
• Two high speed PWM outputs on other two I/O Pads – for servos, LEDs, etc
• All three pads 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 I2C or Serial available on two pads so you can connect to any I2C or Serial device with true hardware support (no annoying bit-banging)
• Same Reset switch for starting your project code over
• On/Off switch built in
• JST battery connector for plugging in AAA’s or LiPoly battery (no built-in LiPoly charging so it is safe to use with NiMH/Alkalines)
