I am thinking about producing one of my prototypes, the Adafruit Sensor Shield. It allows the easy integration of Adafruit’s MicroSD breakout board and one of their accelerometer breakout boards to their Arduino. If enough people are interested I would start a project on Tindie or Kickstarter. I’m thinking a PCB only price of $6-$10, depending on how many are interested, PCB manufacturer, etc.
The final design has the traces re routed to remove all the right angles, ground plain added, moved the TMP36 to shorten traces, etc. The new boards are being manufactured and I will post the pics when I get them, should be in a week or two.
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.
