Electronic modules


Our electronic modules are pre-assembled circuit boards providing specific functions that will serve as components in a larger system. To create a complete application system you will normally have to add other products besides the module.

Modules are a very convenient way of creating products in small series, and of course also for experimental and educational use.

Documentation can be dowmloaded for most modules from the product page and/or manufacturers home page.

To comply with CE regulations (e.g EMC and LVD) you would normally have to put the module in a suitable enclosure and connect it to a sufficient power source. Other measures may also be required.

  GPS-mottagare 66 kanaler LS20031 5Hz med smart antenn
The LS20031 GPS receiver is a complete 5Hz GPS smart antenna receiver, that includes an embedded antenna and GPS receiver circuits. This low-cost unit outputs an astounding amount of position information 5 times a second. The receiver is based on the proven technology found in LOCOSYS 66 channel GPS SMD type receivers that use MediaTek chip solution. The GPS smart antenna will track up to 66 satellites at a time while providing fast time-to-first-fix, one-second navigation update and low power consumption. It can provide you with superior sensitivity and performace even in urban canyon and dense foliage environments. The capabilities meet the sensitivity requirements of car navigation as a well as other location-based applications. Note: The new version of this module uses the MT3329 MTK chipset. Note: Unit does not contain a connector, however there are 5 bare pads you can solder to.
  ShiftBar Led controller
The ShiftBar is a medium-power RGB LED controller, capable of powering three channels of LEDs from 10mA to 150mA and from 5V to 17V. It's ideal for many common-anode RGB LED bars, such as the Satellite Module 001. It uses the same A6281 controller as the ShiftBrite, with daisy-chainable SPI communication that is simple to use with any microcontroller. Each channel is controlled with its own 10-bit PWM register and 7-bit current control register. A trim potentiometer allows the user to adjust overall current limiting to any desired maximum. The ShiftBar includes six screw terminal headers for wiring your own LEDs, as well as independent power. It also has two 6-pin headers that bring power and communications into and out of the device. Chains longer than four ShiftBars at maximum current should have power attached periodically, to counteract voltage drop along the power wires of a long chain.

  EasyUSB 2Mb
The EasyUSB gives your microcontroller access to 2MB that can be seen as a mass storage device in most operating systems. Now your microcontroller can easily read and write files in a file system that your computer can easily understand. Check the SDK below for examples and libraries. Features: FAT16 file system 2MB memory size 3.0-5.2V input voltage Baud rate: 9600 - 921600 bps DIP8 package
  Power Cell - LiPo Charger/Booster
The PowerCell board is a single cell LiPo boost converter (to 3.3V and 5V) and micro-USB charger in one. The board comes with a JST connector for a single cell LiPo battery, a micro-USB connector for the 5V charge input, and selectable 3.3V and 5V ouput pins (labeled 'out'). There are also two charge pins broken out (labeled 'charge'), so you can use another 5V power source to charge the batteries, if you don't have a micro-USB cable. We've also broken out the power-save and enable pins, so that you can have full control of the switching regulator. The under-voltage lockout enable is also tied to a solder jumper so that you can disable it if you like. The micro-USB charger uses the MCP73831 and allows you to charge 3.7V LiPo cells at a rate of 100mA max. If you want to charge at a faster rate, you will need to connect a separate power supply to the pins labeled '5V' and 'GND' under the label 'charge'. The boost converter is based on the TPS61200 from TI and has solder jumper selectable 5V and 3.3V output, and an under voltage protection of 2.6V (which can be disabled via solder jumper on the back of the PCB). Note: This board does not have reverse polarity protection, so please be sure to recognize the polarity of your connections! Dimensions: 1.03 x 0.95" Features: MCP73831-2 Single Cell LiPo charger 4.2V at 500mA TPS61200 Boost Converter Selectable output voltage 3.3 or 5V 5V @ 600mA max 3.3V @ 200mA max Undervoltage lock out at 2.6V (with disable jumper) Quiescent current, less than 55uA JST connector for LiPo battery micro-USB connector for charge power source Inductor: 4.7uH, 1.2A Sumida CDRH2D18 Over temperature protection
  Electric Imp development platform
We know what you're thinking, "What's the big deal? Looks like an SD card..." Well this is no SD card! The Electric Imp is a WiFi enabled development platform powered by a Cortex-M3 processor core. "Really?" Yup. In essence, the Imp provides an easy, integrated way to connect almost any hardware device both to other devices and to internet services. It's more than just a WiFi card, or even a WiFi module with processing built in - it's an integrated platform that deals with the drudgery of connectivity, allowing you to concentrate on the application instead of the mechanics. It does this by integrating an 802.11b/g/n WiFi transceiver, a great antenna, a Cortex-M3 core and lots of flexible I/O in a tiny package. But the hardware is only part of what makes the Electric Imp an innovative platform. The development environment and workflow is totally cloud-based and in-browser! Simply program the Imp with your WiFi Network information using your iOS or Android smartphone (Optically! No special hardware required!) then log on to the Electric Imp developer website and program your module over-the-air! Development is done in-browser and in a language called "Squirrel," which is a C-like language with extensions to communicate with the hardware interfaces and the service. Thanks to cloud-power, you get many big system benefits like buffered I/O and crash recovery - plus you can push updates to devices in the field with a few clicks. There's even a Planner tool that makes it easy to design interactivity between your Imps. Note: Although, the Electric Imp comes in an SD form factor, it isn't compatible with standard SD devices and we're afraid you can't hack it from a basic SD breakout. Development boards are available and we're working on our very own right now, so stay tuned! Dimensions: 32 x 24 x 2.1mm Features: Super Small Form Factor WEP, WPA and WPA2 encryption Cortex-M3 core gives great performance combined with low power consumption 6 I/O - UARTs, I2C, SPI, analog in and out, PWMs, GPIOs... all selectable under software control No SDK to install, no JTAG pods, no long download times... you develop your code in a browser-based IDE Software that runs on the Imp is written in Squirrel, a C-like language Data passes to and from the service over a TLS encrypted interface
  Switch regulator 5V 1A 78xx compatible
Small switch regulator for fixed output voltage. The package is pin compatible with the 78xx-series linear regulators, but requires no external components or heatsink. Can be used in applications where a linear regulator wont fit or where the input voltage is too high and would cause a thermal overload. The output is short-circuit proof. * Input voltage: 6.5 - 18VDC * Output voltage: 5VDC * Output current: 1000mA * Efficiency: 85% * Temperature: -40 to +85°C * Ripple: max 30mVpp * Dimensions: 11.5 x 7.55 x 10.2mm
  Big Easy Driver
Its the next version of the popular Easy Driver board. The Big Easy Driver, designed by Brian Schmalz, is a stepper motor driver board for bi-polar stepper motors up to a max 2A/phase. It is based on the Allegro A4988 stepper driver chip. Each Big Easy Driver can drive up to a max of 2A per phase of a bi-polar stepper motor. It is a chopper microstepping driver which defaults to 16 step microstepping mode. It can take a maximum motor drive voltage of around 35V, and includes on-board 5V/3.3V regulation, so only one supply is necessary. Although this board should be able to run most systems without active cooling while opperating at 1.7A/phase, a heatsink is recommended for loads approaching 2A/phase. You can find the recommended heatsink in the related items below. Features: Bi-polar Microstepping Driver 2A/Phase Max Max Motor Drive Voltage: 35V On-board 5V/3.3V Regulation Note: This product is a collaboration with Brian Schmalz. A portion of each sales goes back to him for product support and continued development.
