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.
The Tinusaur Starter is a beginners’ kit that will help you start with microcontrollers and the Tinusaur particularly.
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.
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.
A5, the other side of the board:
there is optional cell-button battery mount.
