A 94V-0 design is inherently a thermally conscious design:
Locate the GLOBAL_EN and RUN_PG pins on the schematic. If a pull-up resistor has failed or a physical switch is grounding these lines, the module will remain perpetually asleep. cm4 94v0 schematics
If you can provide the of the specific circuit board you are working on, I can help you identify the exact documentation you need. What specific feature or fault are you trying to trace on the board? Share public link A 94V-0 design is inherently a thermally conscious
Place AC coupling capacitors (usually 100nF) on the TX lines exactly as shown in the reference schematic. HDMI and MIPI (Camera/Display) cm4 94v0 schematics
