DFRduino Leonardo Microcontroller with built-in GSM / Bluetooth SIM808 module. Also equipped with a lithium battery charging module, these features make it ideal for advanced projects such as the IoT Internet of Things, security systems, and real-time machine tracking. Leonardo itself is an improved version of the classic Arduino Uno. The microcontroller has as many as 20 digital send / receive connectors (Uno has 14), of which 12 are analog (Uno has 6) and 7 PWM (Uno has 6). Another difference between these microcontrollers is that the Atmega32u4 microprocessor used by Leonardo has built-in USB (UNO uses an additional component for this), so computers can recognize this microcontroller as a mouse, keyboard, or other USB device.
