Breakout for the LPC2101/2/3 microcontroller

Wearable sensor set appropriate for recording motion on such things as a roller coaster. This board goes in your pocket, and hosts a PJRC Teensy 4.1 to control the sensors and record the data. The other boards go on your shoulder and in the heel of your shoe.

Each board hosts two LSM6DS0 6-axis inertial sensors, an AK09970 3-axis magnetic sensor, and a BME180 pressure sensor. The shoulder board hosts a uBlox NEO-M8U GPS+IMU.

All design files are at https://github.com/kwan3217/kicad/tree/master/WearablePocketometer. BOM is derivable from the schematic, all parts have Digikey part numbers.

Smallest possible Shoe board – OSHPark won’t make a board smaller than this. Only has one 6DoF, and no spot for I2C transceiver. Only uses six wires. Uses castelation connector.

This can still be compatible with the WearablePocketometer, as long as the software expects it.

Wearable sensor set appropriate for recording motion on such things as a roller coaster. This board goes in your shoe, and hosts a set of inertial, magnetic, and pressure sensors. The other boards go in your pocket and on your shoulder.

The intended purpose of the wearable pocketometer is measuring roller coasters, and the shoe one may be the most useful one for measuring a roller coaster cleanly. Since it is in your shoe, you can jam your foot up against some corner of the roller coaster car, to get good rigid contact with the car and good repeatability.
