ESP8266: Use Android Phone to Control ITEAD Rboard

Recently, ESP8266 as a low cost wifi module is a hot hacking issue in Hackaday. These days, our engineer Stan Lee has come up with a tutorial to use android phone to control our product Rboard through this mini wifi module.

Rboard is a unique Arduino board which features 4 channels isolated relays, an XBee socket, and an ATMega328. This board will add relay control as well as wireless connectivity to your projects and it will be a possible solution for smart home applications controlling.

IDSG101 Pocket Digital Signal Generator Available

IDSG101 is a cost-effective digital signal generator, because of its mini design it can even be placed in a pocket. By using a 3 inch full color LCD and resistive touch screen, with an expressive English interface, evey one can get started using this device easily.


  • 65536 colors 240*400 resolutions 3 inch TFT LCD with resistive TP
  • 14 bits high-speed DAC (800M sampling rate, maximum 10MHz output)
  • Max 10V Vpp output
  • Max 32768 dots arbitrary waveform (Built-in 15 kinds of commonly used waveform, 128M storage)
  • Easy Firmware Upgrading
  • Support hand draw waveform

Based on several advanced technologies, IDSG101 can realize some unique functions that common desktop devices have in a small size. Though this device is as small as your hand, it can realize 80M sampling rate, maximum 10 MHz and 10Vpp range output.

Motion Control Music Player

Generally, the ultrasonic module is used for motion control project. In this blog, we will apply the music play shield and ultrasonic module together to make a motion control music player. The music play shield has an on-board SD card socket that is used for music files storage. There is also a USB port for external USB flash disk connecting. Ultrasonic module, we use HC-SR04. This module is not the perfect one, and you can visit the comparing ultrasonic module blog to get more details. When HC-SR04 detects different distances, it will send different signals to tell music play shield to play the next song or the previous one.

We need the components as below:

Iteaduino Mega with 2.8 LCD – DIY a Clock That Can Detect Temperature and Humidity

We’ve used LCD1602 to DIY a clock that can show temperature and humidity at the same time. However, some thought that character screen is too simple to show information, what if a TFT LCD instead? In this blog, we will use 2.8 TFT touch screen to DIY a clock with temperature and humidity detecting.



Plug 2.8 touch shield into left side interface of Iteaduino MEGA 2560, and then connect DS1307 module’s SDA to D22 pin, SCL to D23 pin. Connect s pin of DHT11 module to D25 pin, at last put CR2032 button cell into battery socket in the back of Iteaduino MAGA.

Pins pairing as follow:
// DS1307:  SDA pin   -> Arduino Digital 22
//          SCL pin   -> Arduino Digital 23
//          VCC pin  -> 5V
//          GND pin  -> GND
// DHT11:   S pin     -> D25
//          V pin     -> 5V
//          G pin     -> GND

An introduction to Core EVB

Core EVB is a customized evaluation board for ITEAD Core AW204x, which pinouts the functional pins of AW204x to the corresponding physical interface such as USB ports, SD card slot Ethernet port etc. Moreover, Core EVB provides a 40 pins interface that is compatible with RPI B+, which will help developers utilize the existing Add-on more easily.

Common A20 development boards in the market only provide Line-in/Line-out interface so that they can't drive a loudspeaker directly. However, we add power amplifier so that it can drive 4ohm or 8ohm speaker easily.

The dimension of Core EVB is designed according to an aluminum box, thus, this development board can be installed to IBOX.

Gboard with MQ2 Gas Sensor: DIY Home Fire-alarm system

Gboard is an upgraded arduino mainboard integrated with ATMega328 controller and sim900 module. It can be used as a GSM/GPRS data transfer or wireless communication project development platform.

MQ2Gas Sensor is an electronic brick that can be used in fire-alarm systems to detect hydrogen, isobutane, liquefied petroleum gas, methane, carbon monoxide, alcohol, smoke, propane and other harmful gases.

In this blog, we will do a simple home fire-alarm system by combining these two products together. An available phone calling sim card is needed to plug in Gboard. When MQ2 gas sensor detects the change of air quality: gas leaking or fire smoke, an alarm call will make to your phone automatically.

IBOX as Thin Client

A common desktop costs at least two thousand in china, and sometimes it takes our IT department’s money and labor to fix when the problems of software, system and hardware occur. In order to reduce the investment in IT equipment, simplify the management and improve both efficiency and capacity of problem solving, many company has adopted the Cloud Office.
More information about cloud office, please refer to Desktop virtualization.

To make cloud office come true, first you can run several virtual hosts on a server, which you can realize it by using VirtualBox, KVM, Xen, Hyper-V etc. Second, you are able to run the remote desktop software on the client computer such as PC, Mac, mobilephone, pad, or IBOX.

In this blog, we will use the open source free software Virtual Box as the virtualized tool and cost saving IBOX as the client computer to demonstrate how to deploy a cloud office environment.

HC-SR04 VS. SDM-IO Ultrasonic Ranging Module

There are two products in for ultrasonic ranging. One is the common 4pin HC-SR04, and the other is 3pin SDM-IO. The ultrasonic ranging product can be installed in the previous joystick wireless control car kit so that the car will have the function of barrier detecting. Before installing, we make a comparison for these two products to see which is better for installing in car kit.
