The new ELM325 J1708 Interpreter

This is another vehicle diagnostics interface chip – this time for heavy duty vehicles that use J1708 with J1587 (or J1922). Although these protocols are being phased out (with J1939 replacing them), there are still a very large number of vehicles that use them.

The ELM325 is very similar to our popular ELM327 – the interface is simple, and can be customized with AT commands, the protocol conversion is all taken care of for you, and the circuit only needs a few support components in order to make a complete interface.
