The article provides a reference for using Beetle with Arduino Leonardo, detailing library installation, power supply requirements, and compatibility tips to ensure optimal performance and prevent damage.
Library
Other Supplementary Information
Power supply via micro USB or power interface.
Beetle is fully compatible with Arduino Leonardo，see link for more details in connection：https://docs.arduino.cc/software/ide-v1/tutorials/Windows#toc4, the only difference is to select "Arduino Leonardo "（"tools 〉 board 〉 Arduino Leonardo" in Arduino IDE）.
All codes for Arduino Leonardo can apply to Beetle.
- This product uses DC power supply with a working voltage of 5V. 6V will damage the product by overvoltage.
- This product works reliably between 4.5V-5V; it may work under 3V-4.5V, but the reliability is not guaranteed.
- For large load applications (such as motor control), you need to connect the loaded VCC and GND directly with power supply, and parallel with capacitor over 10uF, in order to prevent restart or malfunction caused by large load transient.
- In Arduino environment, Beetle has the same features as Leonardo with multiple serial ports, Serial used for USB virtual port; Serial1 used for RX/TX port.
