KEYESTUDIO Plus Board for Arduino UNO R3 with Type-C USB Cable, 3.3V 5V 1.5A Output Current, More Powerful Controller Board

It is a microcontroller board based on the ATMEGA328P-AU, fully compatible with arduino rev3 board.It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 8 analog inputs, a 16 MHz crystal oscillator, a USB connection, a power jack and a reset button.It breaks out all the digital and analog pins in the form of 3PIN headers (G, 5V, S). S pins correspond to all 14 digital pins, 8 analog pins. G pins for Arduino ground. V pins for VCC. You can control the voltage of VCC via a slide switch for 5V or 3.3V.When switched to 5V, level on a serial communication port is 5V, the voltage of pins is 5V. When switched to 3.3V, level on a serial communication port is 3.3V, the voltage of pins is 3.3V.It also breaks out 4PIN headers for serial communication and IIC communication. So it is easier to connect external sensors and modules.Flash Memory: 32 KB (of which 0.5 KB is used by the bootloader)SRAM: 2 KB (ATMEGA328P-AU)EEPROM: 1 KB (ATMEGA328P-AU)Clock speed: 16MHzOn-board LED pin: D13 comes with a USB cable 1m This board with headers attached fits nicely into the arduino boards. Another great Arduino alternative.
