   Construction tips

• Seven 3-pin and two 6-pin connectors are included with each controller. Pin header has standard 0.1" (2.54mm) pitch
• How to connect load cell?
  • Excitation voltage (load cell's IN) to +5v and Gnd terminals
  • Load cell output to -IN and +IN terminals
  • If load cell cable is shielded, connect the shield to Gnd
  • Example of connection diagram and connected wires
• What to do with unused inputs?
  • Unconnected buttons will appear as not pressed - just ignore them
  • Unused analog inputs are automatically disabled. They will appear as soon pots are connected and BU0836 is powered up. In other words, if they are not connected - you will not see them
• Which pots are the best?
  • Any value from 1kOhm to 100kOhm will work fine. 10kOhm is a good start
  • Use linear pots (taper B.) Avoid non-linear, log pots with tapers A, D or Y used in audio level controls
  • Any pot would work but the best quality pots are Spectrol (Vishay) and Bourns. They have life expectancy of few million shaft revolutions.
  • Good wiring helps. For ultimately clean signal use shielded wires and ground the pot's case if it's metal
  • Try to use as much of pot travel range as possible
• Building your own racing pedals from scratch?
  • Consider DIY pedal guide from Todd Cannon.
