Features |
*The beetle is one of the smallest Arduino Leonardo board.
*It is compatible with Micro USB so that direct programming and testing is no longer a headache.
*Suitable for artists and designers to make small and delicate Arduino works.
|
*DFRduino Pro Mini is small but powerful. It has a strong chip.
*It performs well even compared with Arduino boards of standard size.
*It can be widely applied to flight controllers, small machines. And it can satisfy people's special requirements for size.
|
*The only difference between the DFRduino Pro Mini V1.3(8M3.3V328) and Pro Mini V1.3 (16M5V328) is that the later has an operating voltage of 3.3V.
*Both of them have 2 analogs I/O than normal main controllers.
|
*The ATmega32u4 chip used by the DFRduino Nano. It looks like the Nano, but the function is more powerful.
*It is the most IO port and UART master controller in microcontrollers.
*It can be widely applied to dual-string communication systems.
|
*DFRduino Nano adopts ATmega328, which is totally compatible with Arduino Nano.
*It is suitable for all scenarios that need to be compatible with Arduino UNO or DFRduino UNO.
|
*Bluno Nano is a mini Arduino master with Bluetooth 4.0.
*It brings more possibilities and freedom to the development of Android and IOS mobile applications.
*It is suitable for Bluetooth developers with special size requirements.
