The BBC micro:bit is a pocket-sized computer that lets you get creative with digital technology. You can code, customize and control your micro:bit from anywhere! You can use your micro:bit for all sorts of unique creations, from robots to musical instruments and more. At half the size of a credit card, you will be surprised at the amount of hardware each board is equipped with, including 25 red LED lights that can flash messages. There are two programmable buttons that can be used to control games or pause and skip songs on a playlist. The micro:bit can even detect motion and tell you which direction you’re heading. It can also use Bluetooth Low Energy (BLE) to interact with other devices and the Internet.
Taking a closer look at the front of the board, we can see the 5×5 LED array that you can use as a light sensor, a tiny screen to draw on, display words, numbers and other information, and the two programmable buttons! On the back of the board you will find the brains of the micro:bit, a 16MHz, 32-bit ARM Cortex-M0 microcontroller with 256KB Flash, 16KB RAM and a built-in temperature sensor. Additionally, the back of the micro:bit is populated by an accelerometer, compass and Bluetooth Smart antenna, as well as a microUSB and two-pin JST connector for different power options. Finally, at the bottom of the board you will find 20 gold-tabbed edge pins and five ring connectors (three for digital/analog I/O, two for power and ground) for hooking up external components. The tabs with larger holes can be easily used with alligator clips to prototype added components quickly.

The Odroid Single Board Computers have been available in our store for quite a while. The most notable of them is the Odroid-C2, which is one of the most cost-effective 64-bit ARM development boards available. With a high performance quad-core CPU it is an alternative to Raspberry Pi 3 model B. It has a faster CPU, twice as much RAM and faster Ethernet than the Pi 3. Compared to the Pi 3, it also offers eMMC slot and 4k video support. The board layout of the Odroid-C2 is very similar to that of the Raspberry Pi. All main connectors as well as the mounting holes are located at the same places making swapping the two board easier.
The Odroid-C2 has a nice looking black PCB as well as a sizable black heat sink, which helps to keep the processor cool at 2Ghz clock speed. Some of the modern operating systems that run on the Odroid-C2 are Ubuntu, Android, ARCHLinux and Debian, with thousands of free open-source software packages available.

A new version of Digilent Analog Discovery USB oscilloscope and multi-function instrument is available in our store. Analog Discovery 2 allows you to measure, visualize, generate, record, and control mixed-signal circuits of all kinds. It is small enough to fit in one hand, but powerful enough to replace a stack of lab equipment.
The new version not only looks more modern, but it also has better electrical characteristics than its predecessor, while keeping its huge functionality. It features among other things:
Two-channel arbitrary function generator,
Stereo audio amplifier,
16-channel digital logic analyzer,
16-channel pattern generator,
16-channel virtual digital I/O,
Two programmable power supplies (0…+5 V , 0…-5 V).
Thanks to great software it allows you to easily draw Bode, Nyquist and Nichols transfer diagrams of a circuit in the range of 1Hz to 10MHz as well as analyze different digital interfaces (SPI, I²C, UART, Parallel).
Diligent published a film presenting the device.
A more detailed description can be found here. In our store you can also get Analog Discovery BNC Adapter Board to enable the use of standard BNC terminated test leads and probes thus turning your Analog Discovery 2 into an even more powerful tool.
Compared to its predecessor, the Raspberry Pi 2 Model B, it has a more powerful Quad Core Broadcom BCM2837 64-bit ARM Cortex-A53 processor running at 1,2 GHz (while the Pi 2 used Quad Core Broadcom BCM2836 32-bit ARM Cortex-A7 processor at 900 MHz). It also features Bluetooth Low Energy (BLE) as well as a built-in BCM43143 WiFi chip, which means no external WiFi adapters are needed. It has improved power management with switched Micro USB power source supporting up to 2.5 Amps allowing you to connect even more powerful external USB devices to your Pi. A minor change is that the micro SD card slot is now push-pull rather than push-push type.
Like the Pi 2, it has:
4 USB ports,
40 GPIO pins,
Full HDMI port,
Combined 3.5mm audio jack and composite video,
Camera interface (CSI),
Display interface (DSI),
Micro SD card slot,
VideoCore IV 3D graphics core.
The Raspberry Pi 3 has an identical form factor to the Pi 2 (and Pi 1 Model B+). All the connectors are the same as those on the Pi 2 making it fully compatible with older accessories. The only difference is that the LEDs are on the other side of the board with WiFi module taking their place. Thus, they may not be visible in non-transparent Pi 2 cases.
