| Area | What to Look For | Typical Fix | |------|------------------|-------------| | | All IC VCC pins connect to a single, appropriately named net ( +5V , VDD , AVDD ). Decoupling caps placed close to each pin. | Add missing bulk capacitor (e.g., 10 µF electrolytic) near regulator output. | | Ground Plane | All ground pins converge onto a single GND net (or split‑ground if intentional). | Merge AGND and DGND if not required to be separate, or clearly label split‑ground zones. | | Signal Routing | No floating inputs, no unconnected outputs. All UART, SPI, I²C, etc., have proper pull‑ups/pull‑downs. | Add 10 kΩ pull‑up to I²C_SCL if missing. | | Clock Trees | Clock sources ( OSC_IN , CLK_OUT ) have proper termination, load caps, and are not shorted to other nets. | Verify crystal load caps match crystal spec (e.g., 22 pF each). | | Test Points | Critical nodes (e.g., VREF , VBAT , RESET , high‑speed signals) have dedicated test points. | Insert TP1 at RESET_N . | | Unused Pins | Unused pins are either tied to a defined level (GND/VCC) or left open with a “No Connect” (NC) annotation. | Tie floating NC pins to ground through a 1 MΩ resistor if they are high‑impedance inputs. | Detailed schematic overviews for Rev 1
If you have a LAE791P REV 20 schematic diagram verified by your own testing, consider sharing it on a public forum with your validation notes. The repair community thrives on collective verification. Decoupling caps placed close to each pin
