This is the Tinusaur Proto v0.1 m2 that I just finished and sent it to OSHPark for fabrication. You can look at the latest schematics on http://123d.circuits.io at this address: http://123d.circuits.io/circuits/66662. Below are the schematics and the PCB design, for reference.
The new prototype PCBs just arrived from OSHPark – great quality as usual. I noticed that there are only few things that I may change before call it official: slightly move some components around so they fit better and become easier to solder; add one jumper for switch on/off the optional button cell battery on … Read more
I have finally managed to finish the first version of the schematics and PCB‘s and to order the first 3 pieces. This work is based on some previous experiments and designs. Schematics The schematics is nothing special – it is the well known minimal configuration for the ATtiny plus just few addition components – some of them … Read more
