Digispark is small system based on a ATtiny85 micro-controller and is programmed using the Ardunio IDE via a USB port. It is great for those projects that don't require a lot of IO pins or use large sketches. While the board is small, sometimes you may want to incorporate the ATTiny85 onto you own printed circuit boards. Once programmed, the USB socket and associated components are no longer required. However most commercial Digispark systems use a SMD variant of the ATTiny85 that is soldered directly to the board making it difficult to transfer the programmed ATTiny85 to your own boards.

This development system allows you to program ATTiny85 microcontrollers in the Digispark environment. By having a Zero-Insertion-Force socket, DIL or SOP packages can be easily programmed and tested. It incorporates its own power supply for testing without being plugged into the USB port. It supports 5V or 3.3V systems.

Using the Digispark system

Any blank ATTiny85 micro-controller will firstly need to be programmed with a boot-loader. This can be done using an Arduino UNO or a USB to ISP board such as the USBTinyISP board. (See https://www.thingiverse.com/thing:3882262 for the one I use).

Once you have your boot-loader installed, you need to ensure your Ardunio IDE has the Digispark software installed. (See https://digistump.com/wiki/digispark/tutorials/connecting) for further instructions.
