Iota V2.03 - Specifications
By default, the PPM signal is positive signal. Like this:
If your remote need negative signal, shortcut the Z servo pin (Yellow Square on the image) to
ground pin (one of the black square pins on the image) and the signal will be reversed like this:
• PPM stroke calibration
o You can determine the stroke of the servo of the three axis like this:
• Be sure that your remote is in trainee mode.
• Press the Center button while turning on the module.
• Keep the Center button pressed for about 2 seconds.
• The X axis servo will shake for about one second.
• Release the Center button.
• The servo will move by little steps in one direction.
• Press the Center button for about 0,5 second to set the limit.
• The servo will shake for about one second at center.
• The servo will move by little steps in opposite direction.
• Again, press the Center button for about 0,5 second to set this other
limit.
• The led will flash 5 times to confirm the calibration.
• NOTE: The 0 – 180 degrees move of each axis of the module will be
constrained between these two limits. You can turn off the module
without lost these settings.
• NOTE: The module will track 0 – 180 degrees of travel. However your
remote and/or servos can limit this below this range.
• Powering the Iota (PPM)
o Use the two pins Power header to apply voltage to the module. It can be 3.7
volts to 6 volts. Note: The 5 volts from USB port is good enough to power the
module.
