Power and ground rails and a voltage regulator, that's what. So I made a 'duino clone with features for Putting In Projects and called it PIPduino.
- Color-coded power and ground rails for each analog and digital pin,
- Dedicated I2C bus with 4 ports and pullups,
- Combo SPI / ISP connector,
- Serial/FTDI connector,
- Onboard voltage regulator, and
- Flexible power options.
Goodbye shields. Use low cost breakout boards instead.
