This is an educational shield for the Tinusaur board that has 4 I/O components - 2 input and 2 output; of which 3 analog and 3 digital:

• LED (output, analog or digital)
• Buzzed (output, analog or digital)
• Button (input, digital)
• Photo-resistor (input, analog)

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.

It’s a kit. You assemble it yourself.

The home of the Tinusaur is at this address: http://tinusaur.org

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

7 Segment MAX7219 Board

Board to hold 1-3 pcs of 7 Segment Display

Board to hold 1-5 pcs of 7 Segment Display.

Same schematic as before, but ISP connector mirrored so it can come out the silkscreen side of the module, while the other pins come out on the component side. Also, added a reset switch. (Digikey part number EG4918CT-ND.)

The discrete components are 0603.

The crystal is an NDK brand, type NX3225GA.

I’m using a 10MHz one so the board can be powered directly from a lipo cell, but 20M and 16M are available in this package.

Untested 1.0 Rev

Add WiFi capability to your 3D printing using one of the AUX ports, I’m currently going to test this using a Rambo Mini, I left the header routed and added jump points instead so you can use it on whatever board you’d like, it’s not ideal but there are so many different AUX configuration that theres not really a one size fits all type of board.

The discrete components are 0603.

The crystal is an NDK brand, type NX3225GA.

I’m using a 10MHz one so the board can be powered directly from a lipo cell.

The programming header is laid out so the pins come out on the component side. There’s another rev on here where it is mirrored to be more breadboard-friendly.
