Description
Metro 328 is fully compatible with the popular module ArduinoMini. This means that it can be programmed throughthe Arduino IDEenvironment with the use of available libraries via the microUSB cable. It has a famous from Uno version, microcontroller ATmega328 with a clock signal of 16 MHz.
|
To run Metro 328, it is necessary to connect the system to computer usingmicro usb cable.Then, inthe Arduino IDE, choose the Arduino Uno board. |
Power
The module can be powered viamicro usb cable with the voltage of 5 V, and via an external device such as the AC adapter connected to pin VIN. The voltage applied to the VIN should be in the range of 6 V to 16 V - manufacturer recommends 9 V.
Programming
Creating and installing software is enabled by free environment supplied by the manufacturer. Implemented bootloader allows you to send the program directly viathe microUSB cable.
