Description
TheDFRobot module compatible with Arduino Leonardo, which allows for programming of the board in a popularArduino IDEusing available libraries. The so-called Arduino Shields will be also collaborating with the DFRobot module.
The board has the Nuvoton microcontroller, equipped with 31 digital inputs/outputs, 6 of which can be used as PWM outputs (e.g. for motor control) and 6 as analog inputs. The system works with the clock signal with the frequency of 72 MHz. The module has also USB connector, DC power socket, RESET button, and the leads used to connect the AVR programmer.
An additional advantage is the connector forwireless communication systems XBee, thanks to which, you can directly attach the module to the board.
DFRobot company introduced colored connectors that facilitate the identification of the leads:
- red- power pins,
- blueanalog pins,
- green- digital pins.
| The manufacturer has prepared a short guide on how to prepare the board to work in the Arduino IDE. |
Power
The module can be powered via microUSB cable and an external device, for example, the AC adapter, the battery or the rechargeable battery. Switching power sources is automatic. The power supply is connected to a standard DC connector. Rechargeable battery or other source should be connected to the pins of the POWER connector.
Programming
Creating and installing the software is allowed by the free environment of the Arduino IDE. Implemented bootloader allows you to send the program directly via USB cable. ISCP connector enables connection of an external AVR programmer.
