The Explorer HAT and Explorer HAT Pro are the perfect prototyping side-kicks for your Raspberry Pi!
The guys at Pimoroni added a heap of useful input and output options that will take your projects to the next level. Great for driving motors, using analog sensors, interfacing with 5V systems, and touch (even fruit based!) interfaces.
Comes fully assembled.
5V tolerant inputs - Hook up your Pi to accept input from 5V systems (like Arduino Uno/Leonardo or 5V Trinkets). A 5-channel buffer is used that will accept anything from 2V-5V as logic high.
5V powered ouputs - 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.
Eight capacitive inputs - Four along the front edge for touch input (labelled 1, 2, 3, 4) and four up the side for attaching crocodile clips to objects (such as fruit, or tin foil) for experimentation!
Four coloured LEDs - Independently controllable LEDs (red, green, blue, and yellow) that make great status indicators.
Four analog inputs (pro only) - A tidy way to integrate analog signals into your project.
Two H-Bridge motor drivers (pro only) - Drive two 5V motors bidirectionally with up to 200mA per channel. Ideal with micro-metal gear-motors to create the perfect little buggy! You can even soft-PWM for full speed control.
