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.

Grzegorz 12.03.2023 Confirmed purchase Translated review
I got a newer version v4.1. The diagram shows that in this version the clock and SPI data lines were brought out to the J2 connector. Dreamer Nano works seamlessly with the Arduino IDE. I launched the first project - hula. A version without goldpins would be useful, but it's rather a request to DFROBOT.
