MKIV master controller V2

Long ago, when Simchair only existed as an idea in my mind, I mostly tried to use its prototype to control my Trex 450 and used Arduino UNO as the master controller. It had no native USB support and was generally a pain, but one thing was good about it – the reliable and strong USB-B socket. I was never happy with the micro USB one on the Leonardo – so I finally decided to redesign the controller and addressed a few of its problems. Here’s what was changed:

  • changed size of the box to 100x90mm
  • brittle micro USB socket on the board changed to USB-B socket glued into the box
  • 5th I2C socket added (the box needed to become larger to fit the new USB socket)
  • strengthened the front panel so it won’t be bending because of hot glue
  • removed the reset button (never used it)
  • added a rib that will help to hold sockets in place and protect the board from glue
  • fixed nut sockets height and chamfered their edges
  • new rounded design

I will publish the files after some testing.
