Micro J1939 is a small-footprint, commercial-grade implementation with advanced features. Ideal for situations requiring medium configurability during run-time and great performance on any type of platform.

The base stack contains everything to develop a fully standards compliant J1939 node where all transmitted or received PGNs are eight bytes or less.

Portable. Micro J1939 is written in 100% standard ANSI C code allowing for straightforward porting. For targets without standard support packages, designers familiar with their target processor can easily perform the port themselves. Or, ask us for a quote to add support to your target!

Compact. ROM Specifications: 4K - 14K bytes depending upon processor and options selected.

An Affordable Pricing Structure. Micro J1939 offers a low, one-time fee and no royalties on deployed products and includes all source code with every purchase.
