Keyestudio UNO R3 Type-C Board
INTRODUCTION
The processor core of the UNO R3 BOARD is ATMEGA328P-AU, which is fully compatible with ARDUINO UNO REV3. It comes with 14 digital input/output pins (six of which can be used as PWM output), 6 analog inputs, a 16MHz crystal oscillator, a USB port, a power interface, an ICSP interface, and a reset button.
Among them, ICSP can burn firmware for TMEGA328P-AU. Since we have burned the firmwarefor this chip before it go out, so it is generally not used. When in use, we power the board through the USB cable, external DC power supply (DC7-12V), or the Vin GND (DC 7-12V).
