- 아두이노 IDE를 이용하여 프로그래밍이 가능합니다. (UNO선택)
- 제품의 주요 특징입니다.
- ATmega328 brains - This popular chip has 32KB of flash (1/2 K is reserved for the bootloader), 2KB of RAM, clocked at 16MHz
- Power the METRO Mini with 6-16V polarity protected on the Vin pin, or plug the micro USB connector to any 5V USB source.
- METRO has 20 GPIO pins, 6 of which are Analog in as well, and 2 of which are reserved for the USB-serial converter. There's also 6 PWMs available on 3 timers (1 x 16-bit, 2 x 8-bit). There's a hardware SPI port, hardware I2C port and hardware UART to USB.
- GPIO Logic level is 5V but by cutting and soldering closed a jumper on the bottom, you can easily convert it to 3.3V logic
- 5V onboard regulator with 150mA out, 3.3V 50mA available via FTDI chip
- USB to Serial converter, there's a genuine SiLabs CP2104 hardware USB to Serial converter that 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
- Four indicator LEDs, on the top of the PCB, for easy debugging. One green power LED, two RX/TX LEDs for the UART, and a red LED connected to pin PB5 / digital #13
- Easy reprogramming, comes pre-loaded with the Optiboot bootloader
- Beautiful styling by PaintYourDragon and Bruce Yan, in Adafruit Black with gold plated pads.
특징
- ATmega328 microcontroller with Optiboot (UNO) Bootloader
- USB Programming and debugging via the well-supported genuine FTDI FT231X or the SiLabs CP2104
- Input voltage (Vin): 6-16V (a 9VDC power supply is recommended)
- 5V logic with 3.3V compatible inputs, can be converted to 3.3V logic operation
- 20 Digital I/O Pins: 6 are also PWM outputs and 6 are also Analog Inputs
- 32KB Flash Memory - 0.5K for bootloader, 31.5KB available after bootloading
- 16MHz Clock Speed
- Adafruit Black PCB with gold plate on pads
- 18mm x 44mm x 4mm / 0.7" x 1.7" x 0.2"
- Weight: 3g
- Derivative of "Arduino UNO R3 Reference design"
- Open source hardware files on github!
- Fritzing object in the Adafruit Fritzing Library
- ATmega328P product page
- Mac & Windows People! Don't forget to grab & install the FTDI VCP drivers from FTDI and the SiLabs CP210x drivers from SiLabs to make the COM/Serial port show up right! The default drivers may not support the interface chip!
