ChApTEr 2 ■ hArdwArE for IoT SoluTIonS
It’s based on the ATmega328 processor and has 14 digital I/O pins, of which 6 can be used as PWM
output, and 6 analog input pins. The Sippino board has 32KB of flash memory and 2KB of SRAM. Figure 2-9
shows a Sippino with breadboard headers.
The Sippino doesn’t have a USB connection, so you have to use an FTDI cable to program it. The good
news is you need only one cable no matter how many Sippinos you have in your project. I have a number of
Sippinos and use them in many of my Arduino projects where space is at a premium.
The shield dock is an amazing add-on that lets you use the Sippino as if it were a standard Uno or
Duemilanove. Figure 2-10 shows a Sippino mounted on a shield dock.
