A big thanks goes to whereswally606 for keeping this project alive. Massive credit to Lebowski for the awesome firmware and design changes to the 15V power supply.
I have the PCB's made at OSHPark in Oregon, USA where you only need to upload the .kicad_pcb file. I have no affiliation with OSHPark, I get a good quality product at a fair price. If you want to plot gerbers you can do that from within KiCad to have the boards made at the manufacturer of your choice. Any questions, fire away.

Yes kudos to whereswally606 ando Lebowski
Do I send the PIC to either for the programming?
Cheers

Good to hear from you.
harrisonh said:Right, RS232 can go down to -15V, and requires at least -3V for logic high.
What I'm wondering is why the signals are called RS232 in the schematic. They look to me like just 0 to 5V signals, albeit inverted with NPN inverters.

Yes you can. A FTDI TTL to USB adapter connected directly to the DSPIC works.
harrisonh said:What procedure would cause data to get saved? And why would you not want it to be saved?
Also, I'm pulling SETUP to ground, which is pin 38, not pin 19. I'm assuming it was carried over from a previous design.

The posted schematic shows setup on pin 38, where do you get pin 19 from ? If you are calibrating HALL sensor offset you press the setup button to save the collected stats to memory, it is all in the manual.
