This is one of the latest OnStep PCB designs of Howard’s.  Howard allows GDA to sell these PCBs as they do have a non-commercial licensing applied to them.

This PCB will only work with OnStepX. Which is the latest version of the OnStep family of software and also considered beta.

This design is still considered Beta.  Howard myself and a few other have tested the design and so far we have found no problems or flaws in the design.

More information on this PCB can be found at these URLs.  Please read this information closely and becuase these are considered beta this information is subject to change.

This PCB uses the extremely fast Teensy MCU.

The Teensy 4.1 can be found on this website.  If you are not in the USA and want me to sell/ship you one please contact me and i can arrange it to save on shipping outside of the USA.
