#hataday Motor HAT for Raspberry Pi @raspberry_pi #raspberrypi #hat

Dc Motor + Stepper Hat

Next up is a spin of our popular Adafruit Motor Shield but in HAT form. We can control 4 DC motors or 2 Steppers (or combination) and to allow for microstepping and precise motor control, a PCA9685 acts as an I2C PWM driver/GPIO controller.

What’s a PI HAT? Glad you asked!

INTRODUCING RASPBERRY PI HATS

In a nutshell a HAT is a rectangular board (65x56mm) that has four mounting holes in the (nicely rounded) corners that align with the mounting holes on the B+, has a 40W GPIO header and supports the special autoconfiguration system that allows automatic GPIO setup and driver setup. The automatic configuration is achieved using 2 dedicated pins (ID_SD and ID_SC) on the 40W B+ GPIO header that are reserved for an I2C EEPROM. The EEPROM holds the board manufacturer information, GPIO setup and a thing called a ‘device tree‘ fragment – basically a description of the attached hardware that allows Linux to automatically load the required drivers.

Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
