Servo Tester
Version 1 - Last update: Oct 26, 2015

This servo tester gives better results because the first 555 sets the main frequency and the second the duty cycle. So it better approximates a real servo signal.

  1. The first is an astable multivibrator at 41-60Hz. Centered on 50Hz.
  2. The second is a timer pulse from 0.7 to 2ms. Centered on 1.5ms. These are good Servo control values.
  • This layout is in through hole components - not SMT.
  • Rfreq pot can be a preset. The other will be used a lot so should be a pot.
  • Mounting holes added.
