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..
Aoicrie 5pcs PCA9685 16 Channel PWM Servo Motor Driver PCA9685 IIC Module 12-Bit, for Robot or for Raspberry pi Shield Module servo Shield
It is 5V compliant, which means you can control it from a 3.3V microcontroller and still safely drive up to 6V outputs (this is good for when you want to control white or blue LEDs with 3.4+ forward voltages)..
Communication Interface: IIC, PCA9685 contain an I2C-controlled PWM driver with a built-in clock..
6 address select pins so you can wire up to 62 of these on a single i2c bus, a total of 992 outputs..
12-bit resolution for each output - for servos, that means about 4us resolution at 60Hz update rate..
16 Channel PWM/Servo Driver IIC interface-PCA9685 for arduino or for Raspberry pi shield module servo shield..
SunFounder Mega 2560 R3 ATmega2560-16AU 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)..
The mega 2560 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..
With this Ethernet Shield, for Arduino board can be used to connect to internet. It can be used as server or client. Directly plug puzzle board, no soldering required..
This Ethernet Shield is directly compatible with Arduino official Ethernet Library. It adds a micro-SD card slot, which can be used to store files for serving over the network..
