Introduction

KEYESTUDIO R3 with pin header interface is a microcontroller board based on the ATmega328. It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analo g inputs, a 16 MHz ceramic resonator, a USB connection, a power jack, an ICSP header, and a reset button.

It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started.

For convenience of wiring, we designed electronic brick 3pin interface corresponding to all 14 digital pins, 6 analo g pins, 1 pin header for serial communication and 1 for IIC communication. It also has a toggle switch. When switched to 5V, level on serial communication port is 5V, voltage of pins is 5V; When switched to 3.3V, level on serial communication port is 3.3V, voltage of pins is 3.3V.
