Got it working with another ST VL53L5CX-SATEL board after watching a youtube video where someone struggled for 2 hours to understand how to hook-up the ST board. For anyone who searches and reads this.
There are 9 pins on the breakout board starting furthest from the sensor connection to Photon>
o INT n/c
o I2C_RST n/c
o SDA D0 (no pull-up)
o SCL D1 (no pull-up)
o LPN n/c
o PWR_EN 5V/VIN
o AVDD 5V/VIN
o IOVDD 3V3
o GND GND
Time to move on to some data processing pipeline design - probably upscale to 64 x 64 matrix to enable some better object analysis, shapes, edges and movement.
