Post Tiny85 Development board (HCDVBD0025)

This tiny and low cost AVR development board is great for compact projects or projects that only requires a few IO pins. Based on the 8 pin Atmel ATTiny85 processor it allows for an incredibly small form factor. It also has the advantage of including a micro usb interface that allows the processor to be programmed via a USB power without the need for any download adaptors. Additionally the board also comes pre-programmed with the Arduino bootloader and test blink sketch. Please note that to use with the Arduino development environment you will need a modified version of this software (see below).

This development board is based on the DigiStump Digispark reference design and is released under the Creative Commons Attribution-ShareAlike 3.0 License available here:

Technical question for this product should be directed towards Hobby Components.

The standard Arduino IDE does not provide direct support for Tiny85 based development boards. You will need to use a modified version of this environment. This can be downloaded here:

http://sourceforge.net/projects/digistump/files/

The Zip files are prefixed with:

DigisparkArduino-Win32 For Windows
DigisparkArduino-MacOSX For Mac
DigisparkArduino-Linux32 For 32 bit Linux
DigisparkArduino-Linux64 For 64 bit Linux


Drivers are found in the usual driver folder within the IDE. To program the Tiny85 development board via the Arduino IDE you must select:

Tools>Board>Digispark (Tiny Core)
Tools>Programmer>Digispark

When programming the board make sure the USB is disconnected. You will be prompted by the IDE when to connect the board.

Hi, is this tiny board not able to program with the on-board bootloader
or I've been wrong of that tought?

It is programmed with a different version of the Arduino software, and the program is loaded on power-up. Once you set the program to program, it tells you to reset the board by unplugging it and plugging it back in, as it boots up, it loads the program.

I guess this will be deleted by Admin, not sure why he deletes messages without giving us feedback on why.

@JoeM Sorry for having to delete your post. We want to keep this forum as open as possible but we do ask that isn't used to advertise competitors products.

@lpl

You can find a link to the modified Arduino IDE in the first post of this thread. The latest version of the Arduino IDE does actually support ATTiny devices via its board manager but we have yet tested it with this development board so we can't confirm it will work at the moment.

I had to download a separate version from what I was using on the mega, Uno, and Nano. It was simple, but separate. I used it to program a Tiny85 kickstart board.
