    The USBASP windows driver was previously based on libusb-win32. The certificate on the base drivers have expired and the library has now been superseded by libusbK. Earlier today we packaged up the driver and uploaded it to the server. You can now download it from the location below.

    This driver should work with version of Windows XP right through to 8.1 and the version 10 preview. (both 32 and 64 bit editions). Because the driver is signed, there should be no need to disable driver certificate enforcement or use Zadig.

    The USBASP windows driver is based on libusb-win32. A while back they released version 1.2.6 and this has now been packaged up for the USBASP. The download link is below:

    This driver should work with version of Windows, XP and higher (both 32 and 64 bit editions).

    Until now, the USBASP windows driver wasn't signed. On older versions of windows this was't too much of a problem as you could override the signature error. On Windows Vista x64 and Windows 7, it is almost a show stopper.

    Various methods have been suggested including a utility called Driver Signature Enforcement Overrider or Pressing F8 at boot time and selecting Disable Driver Signature Enforcement. These approaches were far from ideal.

    With the release of libusb-win32 version this is a thing of the past. A new USBASP driver is now available; is based on the libusb-win32 driver; and supports 32 and 64 bit windows. It is partially signed which means windows still produces a warning during installation, but that warning does not prevent installation of the driver.

    OK, now for the installation procedure...

    28 Pin AVR Development Board - Version 1.6

    We released the 28 Pin AVR Development Board back in 2008 and since then it has gone through many iterations. This week we release version 1.6 which adds 4 improvements. These improvements were based on customer feedback and we are very grateful for the feedback. Please keep it coming.

    10 extra components for atmega168 development kit

    The ATMEGA168 Development Kit now comes with 10 extra components for the power supply block. Specifically that includes:

    When the ATMEGA8 Development Kit becomes available again, it will also have these extra components.

    Version 1.5 of the 28 Pin AVR Development Board is now available. As before we have incorporated a number of changes that people had asked for.

    New version of Protostack AVR 28 pin board

    The most notable change is a figure-8 shaped hole for mounting the voltage regulator. This configuration allows for both Input/Ground/Output (IGO) and Ground/Output/Input (GOI) style voltage regulators. Other changes to the power supply include the addition of a diode to protect against reverse polarity and a resettable fuse.

    This month we release version 1.4 of our 28 pin AVR board. As with the previous releases, we've incorporated changes our customers recommended. Keep the feedback coming, cause we love it.


    The most notable change is the inclusion of a power supply area. In previous versions you could create a power supply by using the generic prototyping area, but this makes it much easier.

    Breadboards are great and so are protoboards that are based on breadboard layouts. Well most of the time 🙁 . They both have problems when you need to use IDC connectors, dual row headers or any other component that has 2 rows of connectors on a 0.1" (2.54mm) grid.


    The problem is due to the fact, that you need the connectors on each row to connect to a different terminal strip or protostrip. This cannot be done because each set of terminal strips/protostrips is separated by a 0.3" (7.62mm) gap.

    The Prototyping Board, full size, style 2 with IDC support addresses this problem by having an area on one edge of the board, specifically for IDC connectors and dual row headers.
