메트로 M0 익스플레스 보드-CircuitPython, ATSAMD21G18
(Adafruit METRO M0 Express
- designed for CircuitPython - ATSAMD21G18)
개요
- 본 제품은 ATSAMD21G18 ARM Cortex M0+칩을 탑재하고 있는 Metro M0 Express 보드입니다.
- CircuitPython으로 프로그래밍이 가능한 제품입니다.
- UF2 bootloader 가 미리 탑재되어 있어 보드를 USB에 연결하면 디스크 드라이브로 나타납니다.
- 프로그램할 펌웨어를 간단하게 끌어다가 디스크에 놓으면 프로그래밍이 됩니다.
- 알림: CircuitPython은 미리 로드 되어 있지 않습니다. 문서섹션의 가이드를 참고하셔서 설치 바랍니다.
특징
- ATSAMD21G18 @ 48MHz with 3.3V logic/power
- 256KB of FLASH + 32KB of RAM
- 2 MB SPI Flash chip
- No EEPROM
- 32.768 KHz crystal for clock generation & RTC
- 3.3V regulator with 500mA peak current output
- USB native support, comes with USB bootloader and serial port debugging
- You also get tons of pins - 25 GPIO pins, 5 more than the Metro 328
- Hardware Serial, hardware I2C, hardware SPI support
- PWM outputs on almost all pins
- 6 x 12-bit analog inputs
- 1 x 10-bit analog output (DAC)
- Built in NeoPixel on pin #40
- Pin #13 red LED for general purpose blinking
- Power on/off switch
- 4 mounting holes
- We also include 4 rubber bumpers to keep it from slipping off your desk
- Reset button
- Adafruit Black PCB with gold plate on pads
- Dimensions: 71mm x 53mm / 2.8" x 2.1"
- Height (w/ barrel jack): 13mm / 0.5"
- Weight: 20g
- Power the METRO with 7-9V polarity protected DC or the micro USB connector to any 5V USB source. The 2.1mm DC jack has an on/off switch next to it so you can turn off your setup easily. The METRO will automagically switch between USB and DC.
- METRO has 25 GPIO pins, 12 of which are analog in, and one of which is a true analog out. There's a hardware SPI port, hardware I2C port and hardware UART. Logic level is 3.3V
- Native USB, there's no need for a hardware USB to Serial converter as the Metro M0 has built in USB support. When used to act like a serial device, the USB interface can be used by any computer to listen/send data to the METRO, and can also be used to launch and update code via the bootloader. It can also act like a keyboard, mouse or MIDI device as well.
- Four indicator LEDs and one NeoPixel, on the front edge of the PCB, for easy debugging. One green power LED, two RX/TX LEDs for data being sent over USB, and a red LED connected. Next to the reset button there is an RGB NeoPixel that can be used for any purpose.
- 2 MB SPI Flash storage chip is included on board. You can use the SPI Flash storage like a very tiny hard drive. When used in Circuit Python, the 2 MB flash acts as storage for all your scripts, libraries and files. When used in Arduino, you can read/write files to it, like a little datalogger or SD card, and then with our helper program, access the files over USB.
- Easy reprogramming, comes pre-loaded with the UF2 bootloader, which looks like a USB storage key. Simply drag firmware on to program, no special tools or drivers needed! It can be used to load up CircuitPython, PXT/MakeCode or Arduino IDE (it is bossa-compatible)
