Today we’re profiling our own Metro boards – the full-size and ‘mini’ versions. First up the full-size Metro may look somewhat familiar, at least in terms of form-factor-ness:
The size and shape of the Metro is derivative of the Arduino UNO R3, with a few of our own bells and whistles thrown in. Notably those 4 indicator LEDs on the edge of the board between the DC power jack and USB receptacle. Also the device can operate at 3.3V or 5V logic with a simple jumper, and the DC jack even includes a micro on/off switch next to it for easily powering down your project when needed without physically disconnecting the power supply.
To show what that could possibly translate into, here’s an example from Collin Cunningham upgrading a decades-old 2X-L ‘bot with a Metro, Wave shield, and proto shield to accommodate a LM386 amplifier circuit to give his Echo Dot a new look and feel:
Next up is also the Metro, but in Mini form factor!
The Metro Mini comes as a fully assembled and tested board, with bootloader burned in and also a stick of 0.1″ header. Some light soldering is required if you’d like to plug it into a breadboard, or you can solder wires or header directly to the breakout pads. Once headers are installed they can be fitted into 0.6″ wide sockets.
Similar in function but in a different size package is the Metro Mini – at only 18mm x 44mm x 4mm the Mini is truly that, while providing all the power and punch you expect out of the ATmega328 brain. The board can easily be configured for plugging into a breadboard, allowing for rapid prototyping prior to designing your own Metro shield or standalone PCB. The small form factor has a unique look, for example in this Metro Minimalist Clock:
