Are you still looking for SIM908 which has already stopped to produce for most regions and countries ? Nowadays it comes to the recognition and popularity that SIM808 overmatches SIM908 in its cost effect、more functions and inexpensive price. Why? You can find answers below. COMMON POINTS TO SHARE

1. The GSM/GPRS engine is a quad-band GSM/GPRS module that works on frequencies GSM 850MHz, EGSM 900MHz, DCS 1800MHz and PCS 1900MHz.
2. SIM808 and SIM908 features GPRS

We're excited to see that our cooperated project Ruuvi tag has launched on Kickstarter. What's amazing is that it reached it's $10,000 goal in less than four hours.

RuuviTag is a stand-alone Bluetooth 5 ready sensor beacon platform. It can be used as a standard Eddystone/iBeacon proximity beacon but it has

Robot arm is vital to makers among daily projects. Today, I would like to introduce 5 awesome robot arms crowdfund on kickstarter. I'm sure that you can find one suitable or attractive to you.

1. Uarm  uArm is a 4-axis parallel-mechanism robot arm, which is inspired by the ABB PalletPack industrial robot arm IRB460. Uarm is made of arylic or wood, and it's controlled by Arduino-compatible board. It's inexpensive, a relatively simple and basic one. You can control the arm with remote controller, wireless keyboard or ceilphone bluetooth. The wood or acrylic

Outsourcing SMT PCB assembly is a strategic move that saves significant capital on equipment and expertise. It lowers per-unit costs through economies of scale, ensures superior quality via professional manufacturing, and accelerates your product's time-to-market. This partnership allows you to focus on innovation while experts handle production for a competitive edge.

One raspberry pi 3 board is enough to help you make a simple computer all by yourself(click here  learn how-to). So, what will happen if we connect several pi boards, that is a supercomputer. Here I collect 5 raspberry pi cluster projects as your reference to learn to make a raspberry pi cluster supercomputer.

Here we collect 10 tips regarding of the most common problems while dealing with PCB Prototying orders. To make sure that you get the boards smoothly, you can have a look at the suggestions. 1.Please don't foget to generate the drill file and add it into your gerber file. 2.Please remember that the board outline must be included at least in one layer if there isn't GML/GKO/dim layer. 3.The minimum copper line width is 0.15mm for normal PCB service. 4.The minimum silkscreen width is 0.15mm and minimum height is 0.8mm. 5.The minimum panel size for V-cut is 8*8cm. 6.Please don't forget to leave a message on your order if you have some special requirements. 7.Please don't let the drill hole break the copper line. 8.Please choose

As a engineer, it’s lucky enough to work for a company that make up with a group of maker. Because we often encounter some problems in our life, our manger allow us to put our creativity into full play due to the opened atmosphere, we can build lots of funny applications to solve the problem.

Recently, we have recruited a number of new workmates, so there have something embarrassing happened, sometimes when I went to the toilet and found that both of the two toilets are occupied, once I complain to kevin about it, then he said: If there is a kind of indicator LED like an airplane toilet lights, so we could know whether the toilet be used. Good idea! I praised him: “hey! Boy! You are really a genius! ” OK, now we have prepared everything, let think about that if you want to achieve remote control, what we need to do? The first role is the most popular platform board -ESP8266, as it happens, we have get some ESP8266 IOT Board just recently, it can achieve wireless control easily, and the most important thing is it cheap enough.

The main function of the project is when the toilet was using, the indicator will show the state of the toilets remotely, just like the toilet indicator in the plane.
