|---|---|---|---|
| 1 BOM / month (10 rows max) | 5 BOMs / month | 30 BOMs / month | Unlimited |
Schematic Generator
Start from a template circuit: 555 astable or monostable, LM317 regulator, LED driver, transistor switch, op-amp amplifier or voltage divider. Enter your values and get the computed parts, a drawn schematic and a BOM, each linked to its calculator and part pages.

| 5 schematics / month | 20 schematics / month | 100 schematics / month | Unlimited |
Hardware Debugger
Pick the symptom (Arduino won't upload, power supply has no output, 555 not oscillating, relay chatter) and follow the steps. Each step is a measurement with the value you should expect, so you know which branch to take next.
