Product description:Dreamer Nano v4.0 - compatible with Arduino
Dreamer is compatible in terms of programming and description ofArduino Leonardooutputs. It means that it can be programmed throughArduino IDE environmentusing available libraries. DFRobot module is characterized by very small size: 45 x 20 x 20 mm, so that it can be accommodated in small, cramped areas such as electrical wall boxes.
The board contains an ATmega32u4 microcontroller equipped with 20 digital inputs/outputs of which 7 can be used as PWM outputs (e.g. for motor control) and 12 as analogue inputs. The board is clocked with a 16 MHz clock signal. The module also has: microUSB connector, socket, RESET button and outputs for connecting the AVR programmer.
|
In order to run DFRduino, you have to connect the circuit with a computer using USB cable and select Arduino LeonardoboardinArduino IDE environment. |
Power supply .
The module can be powered viathe USB cable andan external device, e.g. mains adapter, battery or rechargeable battery. The battery or other source is connected to the VIN and GND pins.
Programming
Creation and installation of softwareenables freeArduino IDEenvironment. Implemented bootloader allows you to upload program directly viaUSB cable.ISCP connector allows to connect externalAVR programmer. Detailed description can be found indocumentation and tutorial.
