This is an improved replacement for the PC board that sits behind the front control panel. It is a newly-designed circuit for the 8", 10", and 12" Meade LX200 "Classic" telescope.
Redesigned high-side current measurement with clean grounding.
All connectors and connector hardware included.
Easy installation with no soldering needed.
A PDF document with instructions for installing the board is available here: installation.pdf
Note that this product does NOT include the fuse or battery, but they can be simply transferred from the old board. For reference, the battery is a coin-type, CR2032 or equivalent. The fuse is a 1.0 Amp, Slow-Blow type.
This design improves upon the original:
Measurement of current for the LED bar display is done using a low-drop 0.01-ohm sense resistor (10X lower than the original). The sense resistor is on the positive supply rail rather than in series with ground, to improve ground noise. Current handling is enhanced with larger traces for power signals, along with low-impedence ground paths.
