Keyestudio UNO Development Board:
This UNO development board can satisfy all requirements of
microcontrollers. All you need to do is to connect it to a computer via a
USB cable and power it by an external power supply of DC 7-12.
The core processor of this board is ATMEGA328P-AU with chip
ATMEGA16U2 which can be UART-to-USB conversion plug.
It has 14 digital input/output pins (of which 6 can be used as PWM
outputs), 6 analog inputs, a 16 MHz crystal oscillator, a USB connection, a
power jack, 1 ICSP headers, and a reset button.
