CR25 line item for a sensor under development rather than in production use.
Test-specific or temporary sensors are wired through the Analog-to-CAN device (8 inputs per unit, compatible with thermistors, pressure sensors, buttons and switches), which sends data on CAN 2 to the DDU11 for translation and relay to the M150.
No part-specific design process is documented. The Custom Electronics subsystem design process applies: 1. Collect the sensor list from every subteam, agree location and type with the designer who needs the data. 2. Split sensors between ECU and dash based on which parameters are engine-critical. 3. Size the charging system and validate it. A custom current measurement board (50 A bidirectional sensing chip, inline on the rectifier-to-PDM wire) measured what the rectifier actually puts back. 4. Build the datalogging parameter list with rates, then check CAN bus load. 5. Validate on a mock endurance: average battery voltage 13.4 V, minimum 12.1 V excluding cranking on CR26I.
