Produktbeskrivning
Adafruit Gemma M0 är ett pyttelitet utvecklingskort för enkla och små projekt. Fast kortet är litet och enkelt, mindre än 3cm i diameter, så finns det gott om kraft! Istället för en ATtiny85 som på den vanliga Gemma finns här en ATSAMD21E18 microkontroller, med en 32-bitars Cortex M0+ med 256Kb Flash, 32Kb RAM, och 48MHz klockfrekvens. Gemma M0 är pinkompatibel med gamla Gemma, fungerar med Arduino IDE och CircuitPython - kortet dyker upp som ett usb-minne med en main.py på, som går att redigera i valfri textredigerare utan att man behöver installera en IDE eller kompilatorer, så Gemma M0 går att använda även på exempelvis ChromeBooks eller datorer man inte kan eller får installera mjukvara på.
ATSAMD21E18 32-bit Cortex M0+
256KB Flash
32 KB RAM
48 MHz 32 bit processor
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)
Each order comes with one fully assembled and tested Gemma M0 with CircuitPython & example code programmed in.
