    IDC Breadboard cable

    IDC connectors don't play nicely with breadboards. The 2 rows of pins are too closely spaced and there are many hacks to get around this issue. In one of our tutorials we recommend taking a IDC connector with right angle leads and bending the leads to make it fit. This does work, but is a pain to get right and it looks ugly.

    The 10 Pin IDC to Breadboard Cable fixes all that. It has a standard 2x5 pin IDC female connector at one end and the other end plugs straight into your breadboard. It doesn't get much simpler than that.

    Small, medium and large prototyping boards

    Ever since we started, we've stocked full size and half size prototyping boards. The standard sizes allow the boards to be stacked together, which is why we called ourselves protostack.

    This month we are stocking a new board, which is approximately a quarter of the size of the full size one. Instead of calling it the "quarter size board", we've renamed all the various sizes to Small, Medium and Large.

    The new board measures 58.42 x 68.58mm (2.3" x 2.7") and is available right now for $2.90.

    Small  prototyping boards

    The diagram below shows the 3 board sizes in relation to each other. As you can see, all 3 board sizes are stackable with the vertical blue lines showing how the mounting holes line up.

    Small, medium and large  prototyping boards

    The small boards can very easy be stacked together as shown below.

    Stack of small boards

    When stacking the small board with one of the medium or large boards, you will need to support one end with a stacking header or something similar. This is shown in the photo below.

    ATMega1284 Development Kit

    The ATMega1284 is an impressive microcontroller with plenty of memory, plenty of pins and loaded with features. The ATMEGA1284 Development Kit combines the microcontroller with our 40 Pin AVR Development Board and a bunch of other components to help you build ATMega1284 circuits faster.

    The kit is nearly identical to the one that Tweak Town reviewed, and gave a "Must Have, Best Features Award". The only differences are a better microcontroller and a faster crystal oscillator.

    The board is engineered for flexibility with many different configuration options available. It also sports a huge prototyping area that resembles a breadboard with power busses snaking in and out.

    The kit is available right now for just $26.60

    ATMega1284 and Resistor Networks

    We've been selling many different AVR microcontrollers for some time. This week we add the ATMEGA1284 to our lineup.

    The ATMEGA1284 is quite impressive with 128K of flash and 16K of RAM. It comes in a 40 pin through-hole PDIP package, has the same general pinout as the ATMEGA32A but runs faster and has more features. Like the ATMEGA32A, in can be used with our 40 Pin AVR Development Board.

    16 x 2 character LCD module with blue backlight and white text

    Welcome to 2014, I think it's going to be a good one. Let's start the year with 3 new products

    First up we have 16 character x 2 line Blue LCD Displays. They are just like the Yellow/Green ones we've had for a while, except the color is different. Because they use a HD44780 compatible controller, you can use standard libraries to drive them.

    If you've never used these type of displays before, the following tutorials will be useful

    8 Bit Logic Level Converter

    More and more devices run on 3.3V or even less. Some have 5V tolerant data pins, but others can be damaged with 5V. The SN74LVC245A 8 Bit Logic Level Converter fixes that problem.

    The SN74LVC245A is an 8 bit bus transceiver with 3 state outputs. It has 2 buses (A & B), both 8 bits wide. It can transmit from A to B or vice versa, depending on the state of the DIR pin. The input side is 5.5V tolerant and the output side matches VCC when high, so when interfacing with a 3.3V device, set VCC to 3.3V. The datasheet has a lot more detail.

    This post is a new product post, a tutorial and a behind the scenes look, all about Pogo Pins.

    Pogo pins are small spring loaded pins that are used to make temporary connections to circuit boards. They are typically use for automated circuit testing or for programming Microcontrollers.

    Pogo Pins are now available for just $0.60 or $0.54 if you buy more than 10.

    Dual Row Dupont Connectors and Pins

    Just in, we have dual row Dupont connector housings. Like the single row housings, you can use them with the housing-less ribbon cables, male crimp pins or female crimp pins. We stock them in a range of sizes:

    Did we mention crimp pins? Yes. Available in strips of 20 Male and Female pins. Simply crimp them to the end of a wire then combine them with the housing of your choice.

    5 Way Navigation Switch

    This 5 way navigation switch is 5 switches in one and a little like a mini joystick. It switches in 4 directions north, south, east and west or if you prefer up, down, left, right. You can also push down with a nice audible click.

    It comes it a through-hole snap in package but doesn't conform perfectly to a 2.54mm grid. With a bit of bending of the pins it can be made to fit into a perfboard or breadboard.
