Hey!

We have new hardware version for the main board of our caliper. There are two major update.

1. There is an op amp on the board for signal conditioning. You can take a look at the schematics

2. Update regarding mounting the board. You can find more from Ryan's post

Other smaller changes include:

• Fix for the display
• Power is only supplied from the USB and go through low noise LDO
• Boot selector pins are removed and solder jumpers are put instead on the back
• Removed the SN65LVDS1DBV
• Rearrange the debug header, so that a ribbon cable assembly can be used instead of jumper cable (for stlink v2 only)
• Added vias on the peripheral of the board to help with noise. 

If you want to join the project you can get hardware from PCBWay. Gerbers are available on GitHub if you want to use fab house of your choice. 

Next major steps would be to actually get a measurements from the thing :) 

Cheers,

M
