Tired of failing opto switches that are hard to replace? This new design is a direct replacement for the board used on Tron.
The board is assembled with all through hole parts, and very easy to repair.
This board is a variation of the 520-5252-04 quad drop target board, with the connector at a right angle. To do so, some of the LEDs were removed, so there are not all 4 red and 4 green fitted.
As a matter of fact, we are so confident that we will replace or repair the board for a full 12 months from purchase.
