Flavonoid v.01s (I2C)

This is a variant of the Flavonoid. It's a lot smaller, mostly because I designed it using I2C/TWI as a protocol. Once I learned how to code for I2C, I realized I could save some trouble in the schematic design, because SPI uses an extra line per chip for the chip select (hence, sometimes it's called four-wire, one for the clock, data-in, data-out and chip select.) I2C has one clock line, and SDO and SDA.

 

So, the board gets a little smaller and less complicated to design.

 

This is v.01s (I2C) in the skillet.
