The STN11xx/21xx OBD Interpreter ICs are based on the robust OBDLink® technology stack and provide a fast and cost-effective way to add OBD functionality to your project. All OBD interpreter ICs on this page are fully compatible with the de facto standard ELM327 command set, while outperforming the original ELM327 IC in every category: stability, performance, features and price.
STN2120: OBD-II, SW-CAN, MS-CAN
STN2120 improves on the STN1170 with greater performance and expandability. Recommended for new designs.
STN2100: OBD-II
STN2100 improves on the STN1110 with greater performance and expandability. Recommended for new designs.
STN1170: OBD-II, SW-CAN, MS-CAN
STN1170 supports all legislated OBD-II protocols, as well as two proprietary network protocols: GM Single-Wire CAN and Ford Medium Speed CAN.
This IC is not recommended for new designs. Consider STN2120 for your next project.
STN1110: OBD-II
STN1110 supports all legislated OBD-II protocols. Available in a 28-pin QFN-S (6×6 mm) package.
This IC is not recommended for new designs. Consider STN2100 for your next project.
