The DM-U08 is Central and Peripherals 2-in-one Serial pass-through Bluetooth UART module. Users can change roles (Central and Peripheral mode) and serial baud rate and device name via AT command. Parameters such as name and password are flexible to use.
Once it is paired with a central/master Bluetooth device such as PC, smartphones or tablet, its operation becomes transparent to the users.

In this project you will learn to how to make a Raspberry Pi Owncloud server. This is a great way to have your very own personal cloud storage that is hosted your home, business or anywhere with internet access.
Full Tutorial: http://pimylifeup.com/raspberry-pi-owncloud/
As many people are aware privacy is starting to become more and more of an issue. If you’re protective of the privacy of your files, then you will probably be interested in this setup.
You will need to have a Raspberry Pi with Raspbian installed on it. If you don’t you can check out my video on installing Raspbian. This particular tutorial is on the Raspberry Pi 2 Owncloud however this should be backwards compatible with any previous version of the Pi.
In this tutorial we will also take a look at mounting a hard drive so the Raspberry Pi cloud server can store the files without running out of room fast. I highly recommended doing this as you will find a SD card really doesn’t hold much unless you pay for an expensive one.
The overall setup of an external drive is pretty easy but very easy for complications to occur.
Once Owncloud is all setup you simply setup your admin account and you’re all good to go. If you decided not to setup an external drive, then I recommend keeping the network drive as the default.
If you want to access the Owncloud Raspberry Pi outside your network, then you will need to setup port forwarding. I recommend following my tutorial and forwarding a random port to port 80 on the pi.
I hope this video/tutorial has helped you be able to make your own Raspberry Pi Owncloud. If you want to leave feedback, feel free to drop us a comment below or other at pimylifeup.com
Raspberry Pi Alternatives: The Reason Why They Are a Better Buy
Raspberry Pi is not the baddest small computer on this planet, and it is what its rivals are trying to inform the remaining of the world. Now and then, a fresh mini computer is introduced out there promising to be the largest one to conquer Raspberry Pi. In fact, there exists a new Raspberry Pi killer referred to as NanoPi M1 Plus, which is Ubuntu-Linux ready and costs $30.
The Raspberry Pi is launched with four versions over time. These comprise of Raspberry Pi Model B+, Pi 2 Model B, Zero, and the most recently released which is Pi 3 Model B.
Pi 3 was established to guarantee that Raspberry Pi is able to please anybody with a well priced computer for developer work. It has up-graded CPU with the Cortex A53, Hackaday expressed, and runs on 1.2 GHz. At $35, the Raspberry Pi is the most favored of all.
The Raspberry Pi, on the other hand, is not the only single board computer(SBC) for homebrewed projects. There are plenty more available in the market which is less expensive, and then some that can do more than Raspberry Pi for some extra, ZD Net reported.
First off, there is the Omega 2, that has a modular nature empowering programmers to add on Bluetooth or Global positioning system unit incredibly easily. It has constructed in Wi-Fi and flash memory space; the OS is Linux distro based upon the OpenWrt program. The Omega 2 charges $5 and is also able to operate on FreeBSD OS, that is why it really is an excellent option for students.
The BBC Micro:bit charges $16 and is best for students for their studying and prototyping projects. A 32-bit ARM Cortex processor energizes it internally and it stands out from the remainder for the 5×5 LED matrix. This attribute provides 25 separately programmable red Led lights for basic output.
In addition, there is the BeagleBone Black, which charges $55 and just like the Raspberry Pi, is one more community-supported platform both for fans and coders. It truely does work speedy; it could boost Linux in under Ten seconds and can develop in less than Five minutes. It is actually powered by AM335x 1GHz ARM Cortex-A8 as well as 512MB DDR3 RAM.
Yet another one is the NanoPi M1 Plus, which was titled as the most recently released Raspberry Pi killer. At $30, it promises to have a better made layout and design and was in a position to combine significant options such as Wi-Fi and Wireless bluetooth. Additionally, it has got an IR receiver, mic, 8GB memory, and power and reset buttons.
Yet, the most useful function of NanoPi M1 Plus is its power to run Ubuntu-Mate, Ubuntu-Core, and Debian, Beta News described. It’s ideal for business users, developers, hobbyists, and students.
