Description

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.

Included is the populated board, the male and female headers so you can add the socket to your board if needed.

This board is to be plugged into your Speeduino or MegaSquirt ECU and will convert the AC signal from VR sensors to the required DC signal.
It’s pinout compatible with the Speeduino V3 & JBPERF v2.1 VR conditioners.
This design uses discrete components,  not the MAX9926 chip.

This conditioner is non-inverting, set your trigger to falling edge.
