OctosonarX2 Featherwing

This is a branch off from https://hackaday.io/project/19950-hc-sr04-i2c-octopus-octosonar Designing an updated board compatible with the Adafruit Featherwing ecosystem The existing design is 2.7" x 1.8". The Feather footprint is 2" x 0.9" which is never going to fit so this will be an under-wing so will be 2.0 x 1.9. Smaller than the original so there is some squishing to do, especially if I want to keep the 9x4 and 1x2 0.1" headers for the sensors etc. Board should be able to operate standalone and replace the existing design for non feather applications.
