ESP8266 Serial Wi-Fi InterfaceESP8266 is a highly integrated chip designed for the needs of a new connected world. Itoffers a complete and self-contained Wi-Fi networking solution, allowing it to either host the

application or to offload all Wi-Fi networking functions from another application processor.

ESP8266 has powerful on-board processing and storage capabilities that allow it to be

integrated with the sensors and other application specific devices through its GPIOs withminimal development up-front and minimal loading during runtime. Its high degree of on-chip integration allows for minimal external circuitry, and the entire solution, includingfront-end module, is designed to occupy minimal PCB area.

Now your Arduino can get on Wi-Fi without breaking the bank.

Use this module for your next Internet of Things project, home automation, or remote

sensor project.This module adapts the ESP8226 IC for use over a serial connection using simple ATcommands.

No SPI interface or Know-How is required.

Warnings:

This module requires a 3.3 volt supply for VCC, and 3.3V logic. It is not 5V tolant. Connect

RX or TX on 5V Arduino will

destroy this module. You must use a logic level converter, or a 3.3V Arduino

The 3.3V supply on the Arduino Uno has inadequate current capabilit to power this module.You must provide a separate,

higher 3.3V supply(about 300mA or better)

The ESP8225 module is very new on the market and support and documentation for it is

currently very limited.

IIC (TWI) to LCD Interface

1. This is another great IIC/I2C/TWI/SPI Serial Interface. As the pin resources of Arduino controllerare limited, your project may be not able to use normal LCD shield after connected with a certainquantity of sensors or SD card. However, with this I2C interface module, you will be able torealize data display via only 2 wires. If you already has I2C devices in your project, this LCDmodule actually cost no more resources at all. It is fantastic for Arduino based project.

2. I2C Address: 0X20~0X27 (the original address is 0X20,you can change it yourself) 3. Supply voltage: 5V 4. The backlight and contrast is adjusted by potentiometer 5. Come with 2 IIC interface, which can be connected by Dupont Line or IIC dedicated cable 6. I2C Address: 0x27 (I2C Address: 0X20~0X27 (the original address is 0X27,you can change it

yourself) 7. Compatible for 1602 LCD 8. Weight:5g

9. Size:5.5x2.3x1.4cm

RAMPS Pololu A4988 StepStick stepper

driver with heat sink

This product is a breakout board for Allegro’s A4988 DMOS Microstepping Driver with Translator andOvercurrent Protection; please read the A4988 datasheet carefully before using this product. This steppermotor driver lets you to operate bipolar stepper motors in full-, half-, quarter-, eighth-, and sixteenth-step

modes, with an output drive capacity of up to 35 V and 2 A.

The translator is the key to the easy implementation of the A4988. Simply inputting one pulse on theSTEP input drives the motor one microstep. There are no phase sequence tables, high frequency control

lines, or complex interfaces to program. The A4988 interface is an ideal fit for applications where acomplex microprocessor is unavailable or is overburdened.

Connecting or disconnecting a stepper motor while the driver is powered can destroy the driver(More

generally, rewiring anything while it is powered is asking for trouble).1. Maximum output current is 1A2. Simple step and direction control interface

3. Five different step resolutions: full-step, half-step, quarter-step, eighth-step, and sixteenth-step4. Adjustable current control lets you set the maximum current output with a potentiometer, which lets

you use voltages above your stepper motor’s rated voltage toachieve higher step rates5. Intelligent chopping control that automatically selects the correct current decay mode (fast decay orslow decay)

6. Over-temperature thermal shutdown, under-voltage lockout, and crossover-current protection7. Short-to-ground and shorted-load protection

Arduino Uno R3 clone with improvements

Main Changes from the older version:

1. Add two rows of the holes for the pins. So it can be connected with normal DuPontline.

2. Add 3 rows of the holes for wiring.

3. Change the in-line package of ATMEGA328P to flat package.4. CH340G Replace ATmega16U25. CH340G Driver Download link :http://www.5v.ru/ch340g.htm
