Instrument Cluster — Bench Testing and Calibration

The full bench test setup for the custom instrument cluster: laptop for firmware flashing and CAN bus simulation, the ESP32-S3 display board, a CAN bus interface adapter, and test cables. The display is showing live data including 413V battery pack voltage, 53°C temperatures, and odometer reading 371 miles. Getting the CAN bus messages decoded correctly and the gauge sweep calibrated took several sessions.  We faked the ZombieVerter can messages using a esp32.
