KEYESTUDIO Leonardo R3 Microcontroller Development Board with USB Cable Kit for Arduino Project

#ad
KEYESTUDIO #ad - 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, a micro USB connection, a 16 MHz crystal oscillator, an ICSP header, a power jack, 12 analog inputs, and a reset button.

If you don't choose the correct development board type, you’ll need to click the “Tools”, it will cause the compilation to fail to transfer. So this is a place that needs special attention. 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.

Please note: open the arduino ide, then select the board that corresponds to your Arduino. 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.
