Immobiliser using DS1990 chips

[Vermes]

It is a construction of a car immobiliser, using well known and popular DS1990 chips. It is an additional anti-theft protection.

As it was shown – electric schema and printed plate are not too complicated. The plate was designed with use of Protel99SE in a way that it best matches universal housing KM35B.
