| Goal | Recommended Approach |
|------|----------------------|
| Inspect Power‑Rail Layout | Zoom into Pages 1‑2 – check the ±15 V filter caps (C101‑C104) and the on‑board LDO regulator (U301). |
| Adjust Gain | Locate the gain‑setting resistor network (R201‑R204). Changing the resistance ratio will modify the overall gain per the formula:
G = 1 + (R2 / R1) |
| Add Anti‑Aliasing Filter | Insert a small RC filter between IN+ / IN‑ and R301 on the schematic. Use a cutoff frequency ½–⅓ of your ADC sampling rate. |
| Diagnose Noise Issues | Trace the ground‑plane connections on Page 3. Ensure the star‑ground point at GND‑0 is not shared with high‑current digital traces. |
| Create a Custom Footprint | Export the component layout from Page 4 (U301, R201‑R208) into your CAD tool (KiCad, Altium, Eagle) and generate a 2‑layer footprint. | To avoid fake "LM495 Mb 11269-2 Schematic Download
