This dual channel signal conditioner uses special circuitry to accept almost any input signal and achieve a lower price point than other products. Includes on-board indicator LEDs. This unit is compatible with the Speeduino 0.3 and 0.4, and also the NO2C and UA4C designs by WTMtronics and well as many other boards with the same connection layout.
Header pins are included but not attached to save shipping costs.
This conditioner is non-inverting, set your trigger to falling edge.
The first production run of the conditioner had a trace that was somehow missing. It was replaced with jumper wire (as seen in the photo) before leaving our facility. The problem was corrected and later productions do NOT require this jumper wire.
