keyestudio Super UNO R3 Atmega328p Development Board with Pin Header Interface Upgraded UNO R3 with USB Cable Perfectly Compatible for Arduino

• FASTLY TRANSFER AND MORE MEMORY: USB-TTL used ATMEGA 16U2 chip, controller used ATMEGA 328P chip（US ATMEL original）
• UPDATED VERSION: include a 3.3v and 5v switch, efficient DC-DC converter allow it powered of higher voltage power sources(7-20V), current up to 1000MA to directly drive the servos or small motors
• EXPANSION SLOTS : extra 4 I2C pins and an extra serial I/O pins allow you to connect to multiple input/output devices such as bluetooth and other I2C communication module
• EASY TO USE: all IO pins are led out and along with an extra ground and voltage pin, pretty easy to figure out how to use them with the labels, make it really easy to connect up external modules
• EXCELLENT QUALITY: this cool yellow-black design board made of environmentally friendly technology and materials, solder is very clean, everything is aligned nicely, tested before packaging , it is really safe

<b>Introduction</b> <br>keyestudio UNO 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 analog 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. <br>For convenience of wiring, we designed electronic brick 3pin interface corresponding to all 14 digital pins, 6 analog 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. <br><b>Specification </b><br>1.Microcontroller core: ATmega328P-pu <br>2.Working voltage: +5V <br>3.External input voltage: +7V~+12V（suggest） <br>4.External input voltage ( extremum ): +6V≤ Vin ≤ ＋20V <br>5.Digital signal I/O interface: 14 (of which 6 provide PWM output) <br>6.Analog signal input interface: 6 <br>7.DCI/O interface current: 1000mA <br>8.FlashMemory: 32KB (ATmega328) of which 0.5 KB used by bootloader <br>9.SRAM static storage capacity: 2KB <br>10.EEPROM storage capacity: 1K <br>11.Clock frequency: 16MHZ
