Login Open ECU Accessories for prototyping


During initial system prototyping with OpenECU™ electronic control units it is often necessary to connect test and monitoring equipment into the system.

The following range of accessories has been developed to ensure high integrity interconnections can be created quickly within the most demanding prototype environments.

OpenECU BoB Kits





BoB Conversion Kits 

The BoB Breakout Board Kits are designed to provide access to the inputs/outputs of all M-series OpenECU electronic control units. The ECU is connected to one end of the board, and signals can be routed to either an existing vehicle loom or external connectors.

Typical applications include module testing, system development and fault-finding. The external connectors can be used to connect sensors and loads or monitor communication buses, and on-board LEDs indicate the status of digital inputs and outputs.

Connections to ECUs are provided by a custom loom between the Mxxx and the ECU, while a daughter board provides suitable connectors for an existing vehicle loom. Each Mxxx is supplied, as standard, with looms and daughter boards for the corresponding Mxxx OpenECU product. Our engineering services team can design suitable connections for other ECUs that have compatible pin requirements.

There is a common base board used in the BoB Kits for each OpenECU family. Breakout Board Conversion Kits are available that will convert a base board for use with another member of the same family. For example any M2xx BoB Kit can be converted for use with any M2xx family member.


OpenECU Pigtail Looms      


Pigtail Loom products are braided wiring looms of various lengths that have a connector compatible with the target OpenECU at one end and individual stripped wires (pigtails) at the other.


OpenECU Programming Loom      


Programming Loom products are braided wiring looms that have only those connections required to reprogram the target OpenECU.

The looms are terminated with a connector compatible with the target OpenECU at one end and individual 4mm banana plugs at the other end.


Connector Packs       






A range of connectors is available to suit the OpenECU M-Series products.
