Best Atmega168 20au

SunFounder Mega 2560 R3 ATmega2560-16AU Board Bundled with R3 Board and Ethernet Shield W5100 for Arduino

The mega 2560 R3 Board is 100% compatible with Arduino. Powered via the USB connection or with an external power supply. The power source is selected automatically..
The ATmega2560-16au has 256 KB of flash memory for storing code (of which 8 KB is used for the bootloader), 8 KB of SRAM and 4 KB of EEPROM (which can be read and written with the EEPROM library). Comes preburned with a bootloader that allows you to upload new code to it without the use of an external hardware programmer. It communicates using the original STK500 protocol (reference, C header files)..
This version is optimized in the original version, both to ensure consistent and compatible with the original, but also easy to use..
R3 board compatible with Arduino. The board for Arduino use ATMEGA16U2 chip, Faster transfer rates and more memory.R3 board control using r3 ATmega328P chip. Includes new pin configuration (SCL, SDA, IOREF).Clearly print on the female header connector, more precise and easier to use the wire..
With this Ethernet Shield, for Arduino board can be used to connect to internet. Can be used as server or client. Directly plug puzzle board, no soldering required. It is directly compatible with Arduino official Ethernet Library. It adds a micro-SD card slot, which can be ....

1.Nano V3.0 card is 100% compatible with the Nano card, and fully compatible with Windows, Mac and Linux operating system..
2.It uses the chip ATmega328P CH340 instead of FT232RL. You can start with various electronic projects by using the Arduino software (IDE). It has....
3.It can be powered via USB connection, 7-12V unregulated external power supply (pin 30), or 5V regulated external power supply (pin 27)..
4.Nano CH340 controller is a compact board similar to the UNO, smaller and breadboard-friendly than Diecimila..
5.Using Atmel Atmega328P-AU MCU, Support ISP download.

Bootloadered already in the board, easy to get started..
Support power supply by external 3.3V~12V DC power and 9V battery power..
Support serial downloading, 100% Compatible to all Pro MIni series shields and sensors..

The Mega is 100% compatible with Arduino IDE and most of the shields are designed for the Arduino mega R3，RoHS Compliant.
The chip is Atmega + 2560-16au and 16u2, same with the official version..
Improved and expert version: 1. 0 pinout: added SDA and SCL pins that are near to the AREF pin.
Stronger RESET circuit. Use 5. 5 * 2. 1mm DC barrel jack (compatible with 5. 5 * 2. 5mm DC barrel jack).
It contains everything needed to support the microcontroller.
simply connect it to a computer with a USB cable or power it with an AC-to-DC adapter or battery to get started..

【Same function as the original Arduino】It great for learning the basics of how sensors and actuators work, and an essential tool for your rapid prototyping needs.
【CHIP UPGRADE】Upgrade the main control chip to ATMEGA328P-AU.And it same as the original arduino pin layout. It compatible with all expansion boards..
【ADDED A 500MA SELF-RECOVERYFUSE】Compared with the original ARDUINO, a 500ma self-recovery fuse is added, which automatically disconnects the circuit when short-circuited to avoid component damage.Change the plug-in pins of the original ARDUINO to SMD pins to avoid short circuit of the development board contact conductors, which is safer..
【Added 10 LED marquees driven by MOS tubes】which avoids the problem of insufficient output current of the IO port of the single-chip microcomputer, and can directly drive a small DC motor through the IO port..
【EASY TO USE】Change the original USB-B type interface to MICRO-USB interface, which is more convenient to use..

Designed for Arduino for Nano V3.0: The item is a terminal expansion adapter, working very well for prototyping Arduino for Nano projects.
It lables for Arduino for Nano version 3.0, however you can still use this adapter for the older version (just have to remember that A0-A7 are in the reverse order)..
You can use this adapter to easily hook up for arduino for Nano to an outside world via hook up wires.
This item is a terminal expansion adapter, designed for Arduino Nano V3.0..
Nano Terminal Adapter Shield Expansion Board Compatible with Arduino Nano V3.0 AVR ATMEGA328P-AU Module.
