==== Daughterboard Heights ====
 
 
 
* From notes on [https://www.youtube.com/watch?v=HMDGYm91Q1Y How to Make Great Looking Modular Front Panels - Part 3 Module Circuit Board Layout]
 
** The absolute maximum of other boards I've seen is 111,5 mm and the TipTop Happy Ending Kit offers a space of 112,5 mm
 
* 114.8mm measured between 3U Synthrotek rails
 
** 128.5mm - 114.8mm = 13.7mm both sides, 6.875mm per side
 
** 111.5mm daughtercard, leaves 8.5mm clearances top/bottom
 
 
 
==== Part Orientations ====
 
 
 
* For pots with built-in pointers, pot pins go down for pointer to go up at center point
 
 
 
==== Front Panel Jacks ====
 
 
 
* [[Eurorack Panel Jacks]]
 
 
 
==== Alpha Pots ====
 
 
 
* [https://store.synthrotek.com/9mm-Plastic-Shaft-Potentiometer_p_785.html Synthrotek store page]
 
* These pots have the same footprint as Alpha/Synthrotek metal shaft pots, but with a longer shaft.
 
* They are knurled with a white pointer, so they don't need any knobs.
 
* They are suitable for many different Eurorack projects.
 
** .05W
 
** 20% Tolerance
