ULTIMATE GPS PI HAT! “HAT A DAY”… a @Raspberry_Pi HAT we sent off for prototype PCBs for testing #hataday
Say hello to the ULTIMATE GPS PI HAT! It’s part of a new feature we are doing here each day called “HAT A DAY” (sounds like hack-a-day, the site Phil started almost 10 years ago and ladyada is now a judge for in the SPACE contest! This is a HAT a day for a few weeks!)… This is a Raspberry Pi HAT we sent off for prototype PCBs for testing, we’ve sent off many, we’ll post a new HAT A DAY, so stop back soon and see the HATs live on ASK AN ENGINEER each week if we have time during IT’S NOT OUT YET. Yesterday day was PERMA-PROTO HAT.
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.
