Geekcreit® MEGA 2560 R3 ATmega2560-16AU MEGA2560 Development Board With USB Cable (Arduino Mega)
Description:

Arduino compatible R3 Mega2560 ATmega2560-16AU control board with USB cable
Arduino Mega is an ATmega2560 core microcontroller development board. Itself has 54 digital input/output terminals (14 PWM outputs), 16 simulation inputs, 4 UARTs (hardware serial ports), using the 16 MHz crystal oscillator. With the bootloader, download the program directly via USB without having to go through other external writers. Supply part of the optional USB power, or external power using a AC-to-DC adapter and battery.
Rapid growth due to open original code, as well as the concept of using Java (cross-platform) C language development environment for Arduino module. The Arduino can easily use the Arduino language with Flash or Processing ... software communication, to make multimedia interactive works. Arduino development IDE interface is based on open-source principles, allows you to download for use in projects.
Power supply design:
There are two options for the power supply system of the Arduino Mega. USB direct power supply or external power supply. The power supply will be switched automatically. External supply AC-to-DC adapter or the battery can be selected on this control panel. Limit the voltage range of 6V ~~ 12V, but if the voltage supplied is less than 6V, I / O port may not be supplied to a voltage of 5V, and therefore not stable; If the voltage is greater than 12V, the regulator device may possibly overheat and damage the Arduino MEGA. It is therefore recommended that for the operating supply of 6.5 ~ 12V, the recommended power supply is 7.5V or 9V.
The development board have been rigorously tested at the factory.

Specification:

Microcontroller: ATmega2560
Operating voltage: 5V
Input voltage (recommended): 7-12V
Digital I/O pins: 54 (of which 14 provide PWM output)

SONOFF 4CH PRO R3 AC100-240V 50/60Hz 10A 2200W 4 Gang WiFi DIY Smart Switch APP Remote Control Works with Alexa and Google Home (sonoff 4ch pro R3)
Overview:

SONOFF 4CH R3 & 4CH PRO R3 are both 4-gang DIY Wi-Fi Smart Switches designed to give you the ability to integrate smart control into your existing home to enable a smart home. Each smart switch has 4 gangs that can be used to control lights and other home appliances at the same time in four areas of your home. There is a major difference between 4CH R3 and 4CH PRO R3, which is 4CH PRO R3 is designed with an additional function for RF control. The function is purposely adopted to make you turn on/off the device connected with 4CH PRO R3 via the RM433 remote controller.
Actually, SONOFF has ever released two types of 4-gang smart switch (4CH R2 and 4CH PRO R2.) which comes with almost same functions with 4CH R3 and 4CH PRO R3. But all the above units are still different in 3 working modes including self-locking, interlock and inching mode. The new improvement on 4CH R3 and 4CH PRO R3 compared with 4CH R2 and 4CH PRO R2 is for users to set these 3 working modes on eWeLink APP instead of the hardware itself, easier to operate. So you can enable self-locking mode to turn on/off 4 connected devices separately, interlock mode to turn on 1 connected device every time and turn off the rest of devices simultaneously and inching mode to turn on 1 connected device and then make it turn off automatically after a given time (0.5 - 3600s). For the device away from the switch, you can create a moveable space in virtue of a DIN rail to make them be connected. Simply activate devices through your voice when the switch works with Alexa and Google Home smart assistant.


Features:

- Remotely control connected lights or devices via APP
- 3 working modes with self-locking, interlock and inching mode for even remote control garage door and roller blinds
- Support scheduling a timer to make devices automatically start and stop to work
- Customize smart scenes to make the device connected with the switch to trigger other devices
- Share the control permission of devices to other accounts to control together
- Check real-time ON/OFF status of devices on your mobile phone
- Power on state allows users to set the On/Off/Keep status for the connected device before power failure and ensure it remains the arranged status after power restoration

4CH PRO R3 Specifications:

Voltage Range: 100-240V AC 50/60Hz(DC: 9-23V)
