Product Description

KEYESTUDIO Leonardo R3 Board

KEYESTUDIO Leonardo board offers incredible value with its impressive performance, making it a top choice for Arduino enthusiasts.

The Leonardo differs from other Arduino boards using separate USB-Serial chip in that it has built-in USB communication, eliminating the need for a secondary processor.

Power Supply:

The board has 20 digital input/output pins (of which 7 can be used as PWM outputs), 12 analog inputs, a 16MHz crystal oscillator, a micro USB connection, a power jack, an ICSP header, and a reset button.

The keyestudio Leonardo can be powered via the micro USB connection, or via an external power supply jack (DC 7-12V) or even with female headers Vin /GND (DC 7-12V).

Memory Store:

KEYESTUDIO Leonardo R3 Board has 32KB of flash memory for storing code (of which 4 KB is used for the bootloader), 2.5KB of SRAM and 1KB of EEPROM (which can be read and written with the Eeprom library).

Board Model:

Neat little Leonardo r3 board works just like the original!

Another great Arduino alternative. It works fine and the quality is good. The yellow and black theme is unique.
