Description
microOBD 200 is a quick and easy way to add OBD support to any embedded
project. It is a complete OBD-II to UART interface in a DIP-24 form factor,
designed for in-vehicle applications. microOBD 200 uses an enhanced version
of the popular ELM327 command set, supports UART speeds up to 10 Mbps
and is firmware upgradeable.
Key Features
- Supports all legislated OBD-II protocols and J1939 (heavily duty vehicles)
- Fully compatible with the ELM327 command set
- Extended "ST" command set for access to advanced functionality not available
in the ELM327
- UART interface
- Bootloader for easy firmware upgrades
- Large memory buffer
- Solid automatic protocol detection algorithm, connects to more vehicles
reliably
- Smart keep-alive algorithm helps ensure a stable connection on ISO and KWP
vehicles
- Dimensions: 1.3" x 0.59"
Supported OBD Protocols
- SAE J1850 PWM
- SAE J1850 VPW
- SAE J1939
