 Python API

 Four analog inputs - A tidy way to integrate analog signals into your

project.

 Two H-bridge motor drivers - Drive two 5V motors bidirectionally with up

to 200mA per channel. Ideal with our micro-metal gear-motors to create

the perfect little buggy! You can even soft-PWM for full speed control.

 Four buffered 5V tolerant inputs - Hook up your Pi to accept input from

5V systems (like Arduino Uno/Leonardo or 5V Trinkets). We've used a 5-

channel buffer that will accept anything from 2V-5V as logic high.

 Four powered 5V outputs (up to 500mA!) - The onboard darlington array

can supply up to 500mA per channel (but you'll be limited to driving

around 1A total from the board). Ideal for stepper motors, solenoids, and

relays.
