Speedometer Board

Postby jsdevel » Sat Dec 17, 2016 7:43 pm

Hi Jean,

I've found several write ups on using a speedometer with a Frequency to Voltage converter circuit. The controller that's typically recommended is this one by Texas Instruments (LM2917). Here is an example circuit that uses it.

While purchasing the converter isn't that big of a deal, creating the accompanying circuit can be for those who would like to get up and running quickly. The converter is also surface mount which is challenging.

Have you thought of adding a speedo board to your product line?
