Digispark Development System

thingiverse

Digispark is a compact system based on an ATtiny85 microcontroller, programmed using the Arduino IDE via USB. It's ideal for projects requiring minimal IO pins or small sketches. Despite its size, sometimes you may want to integrate the ATTiny85 onto your own printed circuit boards. After programming, the USB socket and associated components are no longer necessary. However, most commercial Digispark systems use a SMD variant of the ATTiny85, soldered directly to the board, making it challenging to transfer the programmed ATTiny85 to your custom boards. This development system enables you to program ATTiny85 microcontrollers in the Digispark environment. With its Zero-Insertion-Force socket, DIL or SOP packages can be easily programmed and tested. It includes a built-in power supply for testing without requiring a USB connection. It supports both 5V and 3.3V systems. Using the Digispark System Any blank ATTiny85 microcontroller must first be programmed with a boot-loader. This can be achieved 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, ensure that your Arduino IDE has the Digispark software installed. (See https://digistump.com/wiki/digispark/tutorials/connecting) for further instructions.
