 File: Prototype 20201017.jpg| An initial "proof of concept" build. Using the first revision of the custom mainboard pcb as well as several off-the-shelf breakout boards from adafruit. Sensor board was a pi-hat protoboard with adafruit sensor breakouts. Unit 00 also served as a test bed for shift register controlled lighting, sticker fit and finish, and printed light diffusers. This prototype utilized a development sensor array and cap and was not indicative of the final version. Construction of this prototype is considered "complete".

 File:Unit01-210929.jpg| This "production" prototype is being used to iron out the remaining problems with integrated systems and hardware. It features a revision 3 mainboard and sensorboard PCB. Unit 01 employs a new case design that attempts to more accurately capture the shape of the Tr-590 Mark VI Tricorder. The case changes are completely superficial and no changes have been made to the underlaying chassis-rail system. Early chassis designs will still work with this new enclosure.
