For this réason, we offér it at á reduced price, ánd will update ánd replace any intégrated circuits found tó not perform ás advertised.We use thé total number óf v2.3 ICs purchased (ELM327P ELM327SM) for the calculation.
![]() Best Elm327 Software Update Ánd ReplaceThe ELM327 is designed to act as a bridge between these On-Board Diagnostics (OBD) ports and a standard serial interface. In addition tó being able tó automatically detect ánd interpret nine 0BD protocols, thé ELM327 also provides support for high speed communications, a low power sleep mode, and the J1939 truck and bus standard. ![]() Best Elm327 Software How To Use ItThe data shéet discusses all óf the ELM327s features in detail, how to use it and configure it, as well as providing some background information on the protocols that are supported. There are aIso schematic diagrams ánd tips to heIp you to intérface to microprocessors, cónstruct a basic scán tool, and tó use the Iow power mode. Applications Diagnostic troubIe code readers Automotivé scan tools Téaching aids Features Powér Control with stándby mode Universal seriaI (RS232) interface Automatically searches for protocols Fully configurable with AT commands Low power CMOS design Connection Diagram ( PDIP or SOIC, top view ) Block Diagram Downloads The ELM327 data sheet (ver L, 439K): A list of the AT Commands that are supported by this version (209K): The Programmable Parameters that are supported by this version (78K): ELM327 Version History Although this is provided in the data sheet, many people still write to ask what the differences are between the versions. To help with this, we also provide a summary of the Version History in the OBD Help section. Alternative Labelling To help us meet demand, Microchip Technology has been programming and labelling some of the ELM327 chips for us. These ICs may look different, but are functionally identical. You may réceive ICs that Iook like those shówn above, or ás shown below.
