If you don't choose the correct development board type, it will cause the compilation to fail to transfer. So this is a place that needs special attention.
The keyestudio Leonardo is a microcontroller board based on the ATmega32u4，It has 20 digital input/output pins (of which 7 can be used as PWM outputs), 12 analog inputs, a 16 MHz crystal oscillator, a micro USB connection, a power jack, an ICSP header, and a reset button.
The Leonardo differs from other boards using separate USB-Serial chip in that the ATmega32u4 has built-in USB communication, eliminating the need for a secondary processor.
This allows the Leonardo to appear to a connected computer as a mouse and keyboard.
Has fcc and ce certification that they are made from environmentally friendly production technology and materials, made function,voltage, current testing before packaging KEYESTUDIO leonardo r3 ELEGOO Mega R3 Project The Most Complete Ultimate Starter Kit w/ TUTORIAL Compatible with Arduino IDE The MEGA complete starter kit with more than 200pcs components, premium quality and 100% Compatible with Arduino IDE

The chip is Atmega+2560-16au and 16u2, same with the official version.
Improved and expert version: 1. 0 pinout: added SDA and SCL pins that are near to the AREF pin and two other new pins placed near to the RESET pin, the IOREF that allow the shields to adapt to the voltage provided from the board. In future, shields will be compatible both with the board that use the AVR, which operate with 5V and with the Due that operate with 3. 3V. The second one is a not connected pin, that is reserved for future purposes.
Stronger RESET circuit. Use 5. 5 * 2. 1mm DC barrel jack (compatible with 5. 5 * 2. 5mm DC barrel jack)
It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with an AC-to-DC adapter or battery to get started. ELEGOO Blue
