This is the Tinusaur User Guide. It contains general information about the Tinusaur Project, the Tinusaur Board, the components that are used as well as some other useful information.

The Tinusaur Project

Briefly, the Tinusaur is a minimal micro-controller hardware configuration based on Atmel AVR ATtiny family of products and more specifically those with DIP-8 case such as ATtiny25/ATtiny45/ATtiny85, ATtiny13 as well as their variations.

The goal of the Tinusaur project is to have a simple, cheap and accessible quick-start platform for everyone interested in learning and creating things.

Tinusaur Starter

The Tinusaur Starter is a beginners’ kit that will help you start with microcontrollers and the Tinusaur particularly.

Tinusaur Schematics

 

There are 4 areas that a Tinusaur board could be divided to: A1, A2, A3, A4. That is applicable for the actual Tinusaur main board as well as any shield boards one could produce.

Tinusaur PCB design and layout

A1, the bottom part of the board:

  • this is the area where the RESET button is placed on the main board.

  • for a shield board that area could be used to put some components and produce a simple circuit.

A2, the mid of the board – heads:

  • there are 2 header – one 2×4 and another one 2×5, they are different for a reason.

  • on the main board, between the headers, is placed the MCU.

  • on a shield board, between the headers, could placed an 8-pin chip or other components.

A3, the top part of the board:

  • there are the minimum required components for the MSU to work – 2 capacitors for the power source and one pull-up resistor for the RESET.

  • jumper for external power – red.

  • jumper to switch on/off battery – yellow.

A4, tip of the board:

  • standard ISP programming connector.

Additionally …

A5, the other side of the board:

  • there is optional cell-button battery mount.
