LCD-LiDAR-SD Teensy Hat

LiDAR board with LCD screen and SD card for logging.

The project is released as open hardware under the CERN v1.2 Open Hardware license.

It uses a LiDAR-Lite v1 or v2 for the rangefinder, and it supports the I2C and PWM modes. The project uses the KiCad Teensy template and footprint from wickerlib.

I've shared the project at OSH Park so you can buy a set of three bare boards for $22.55.

The Teensy 3.2 is available at PJRC.com or at OSH Park as an add-on at checkout.

I'm using a standard 16x2 LCD screen from Adafruit, but you can also get them from Amazon.

The rest of the parts are available at Digikey.
