Description:   1. The EasyDriver is a simple to use stepper motor driver, compatible with anything that can output a digital 0V to 5V pulse. (or 0V to 3.3V pulse if you solder SJ2 closed on the EasyDriver) 2. EasyDriver requires a 7V to 30V supply to power the motor and can power any voltage of stepper motor. 3. The EasyDriver has an on board voltage regulator for the digital interface that can be set to 5V or 3.3V. Connect a 4-wire stepper motor and a microcontroller and you've got precision motor control! EasyDriver drives bi-polar motors, and motors wired as bi-polar. I.e. 4, 6, or 8 wire stepper motors. 4. It provides much more flexibility and control over your stepper motor, when compared to older versions. The microstep select (MS1 and MS2) pins of the A3967 are broken out allowing adjustments to the microstepping resolution. The sleep and enable pins are also broken out for further control.cjmcu made.   Features:   1. MS1 and MS2 pins broken out to change microstepping resolution to full, half, quarter and eighth steps (defaults to eighth) 2. Compatible with 4, 6, and 8 wire stepper motors of any voltage 3. Adjustable current control from 150mA / phase to 750mA / phase 4. Power supply range from 7V to 30V. The higher the voltage, the higher the torque at high speeds 5. Distribution pin, not welded, this module is open source   Note:   Do not connect or disconnect a motor while the driver is energized.This will cause permanent damage to the A3967 IC.

3Pcs CJMCU-MCP4725 I2C DAC Breakout Development Board Module Description: You’ve always wanted to output analog voltages from a microcontroller, the MCP4725 is the DAC that will let you do it! The CJMCU-MCP4725 is an I2C controlled Digital-to-Analog converter (DAC). A DAC allows you to send analog signal, such as a sine wave, from a digital source, such as the I2C interface on the Arduino microcontroller. Digital to analog converters are great for sound generation, musical instruments, and many other creative projects! This version of the CJMCU-MCP4725 Breakout fixes a few issues with the board including the IC footprint, the I2C pinout, changes the overall board dimensions to better fit your projects, and a few more minor tweaks. This board breaks out each pin you will need to access and use the MCP4725 including GND and Signal OUT pins for connecting to an oscilloscope or any other device you need to hook up to the board. Also on board are SCL, SDA, VCC, and another GND for your basic I2C pinout. Additionally, if you are looking to have more than one MCP4725 on a bus, the pull-up resistors on this board can be disabled just check the Hookup Guide in the Documents section below for instructions and tips on doing this. Feature: 12-bit resolution I2C Interface (Standard, Fast, and High-Speed supported) Small package 2.7V to 5.5V supply Internal EEPROM to store settings Package included: 3 x CJMCU-MCP4725 I2C DAC Breakout Development Board Module

FAST AFFORDABLE COURIER SHIPPING TO SOUTH AFRICA New toy for makers who want to build their own smart home system Overview: The wireless switch supports inching /self-locking mode. You can add the device to the APP eWeLink to remote control connected home appliances or devices. In self-locking mode, you can remote turn on/off connected devices immediately. When in inching mode, you have two wiring ways to select, whether turn on 1s and then auto-off or turn off 1s and then auto-on. Remote control by APP EweLink for iOS and Android. Supported functions include remote on/off, timing schedules, device sharing, group management. The self-lock/inching mode wireless switch has two power supply specification: 5V. No matter which specification you select, they have the same functions. Feature: There are two working modes for the module: inching mode and self-locking mode. Press the self-lock/inching mode button to switch between these two modes. When your module is switched to self-locking mode, you can turn on/off the connected appliance instantly. There is two wiring way. When your module is switched to inching mode, you can press on/off toggle button to turn on or off connected device. There are two kinds of wiring way. The first wiring way is to connect COM and NO with an appliance. In this way, when you press the setting button or APP to turn on, the connected appliance will be turned on for 1s and then auto turned off. The second wiring way is to connect NC and COM with an appliance. In this way, when you press the setting button or APP to turn off, the connected appliance will be turned off for 1s and then auto turned on. LED Indicator: There are 3 LEDs, the led beside self-lock/inching mode button indicates the working mode(on: self-locking mode, off: inching mode). The one beside on/off setting button indicates wifi status(enter pairing status: long press the setting button until led fast blink). Another one below the relay indicates relay on or off status(on: turn on the connected device, off: turn off connected device). Add device to eWeLink: Long press the setting button until the LED beside on/off setting button fast blinking. 1. Android: Add Device->select pairing method according to how the LED blinks->enter WiFi name and password->pairing and register->name device 2. iOS: go to phone setting->WiFi-> select the WiFi starts with ITEAD-********, enter default password to connect:12345678-> go to eWeLink->Add device->->select pairing method according how the LED blinks->enter WiFi name and password->pairing and register->name device Specification: Dimension:70.5mm*27.4mm*23mm Operating current: 5V DC Leds: indicate working mode, wifi status, relay on/off status. Two input interface Board consumption: Standby current: 80mA Max input current: 10A Support to control different voltage range Relay lifespan: more than one million times 100M electrical insulation resistance Electric shock voltage: 1000V Relay maximum pull time: 15ms Relay maximum release time: 5ms Operating temperature: -40 degrees to +70 degrees Operating Humidity 40% ~ 80% RH Application: The switch can be applied to access control, turn on PC, garage door, etc. Package includes: 3 x Module 3pcs 5V WiFi Remote Garage Door Opener Controller Work with Alexa & IFTTT Google home Wireless Remote Control Switch 3pcs 5V WiFi Remote Garage Door Opener Controller Work with Alexa & IFTTT Google home Wireless Remote Control Switch 3pcs 5V WiFi Remote Garage Door Opener Controller Work with Alexa & IFTTT Google home Wireless Remote Control Switch
