Toodles optical replacement sensor for the Sanwa JLF with adjustable sensitivity.
The Spark optical control board is an after-market part for Sanwa brand, JLF model joysticks. It replaces the original, TP-MA micro switch board with optical sensors for completely silent operation.
The five pin connector is wired identical to the original TP-MA board it replaces. As long as the Spark pins point in the same direction the original TP-MA pins pointed, there is no need to change anything with the five pin connector.
