This budget pack is an optimized collection of parts and pieces to experiment with Adafruit Metro 328 and the Arduino IDE at home, school or work. Great for students and those that want to get their feet wet, no soldering required!
Includes the Adafruit Metro 328 with thru-hole headers. The Metro is our take on the most maker-friendly Arduino-compatible board. It is the culmination of years of playing with electronics: we wanted to make a development board that is easy to use and is hacker friendly. At the heart is an ATmega328P, with 32KB of flash and 2KB of RAM, running at 16 MHz, the same chip used in the Arduino UNO
- Power with 7-12V 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.
- 19 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. Logic level is 5V but by cutting and soldering closed a jumper, you can easily convert it to 3.3V logic
- USB to Serial converter, there's a 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 front edge of the PCB, for easy debugging. One green power LED, two RX/TX LEDs for the UART, and a red LED connected to pin 13
- Easy reprogramming, comes pre-loaded with the Optiboot bootloader, so you can get started immediately.
- Works with all Adafruit shields!
This pack has only the basics to get you started. That allows us to keep the price low while giving you the choice of what shields, sensors and accessories to add in.
Once you have the pack, check out our free online Arduino IDE tutorials...they're designed for everyone, even non-programmers!
