Inside the pack

Six checks that catch most beginner-to-prototype failures.

Power checklist for electronics projects Power checklist Brownouts, weak USB cables, 3.3V/5V mistakes, regulators, and current spikes.
Module debugging checklist for I2C and sensors Module debug sheet OLED, relays, SIM800L, sensors, ESP32-CAM, and common wiring traps.
Electronics parts buying checklist Parts buying checklist What to buy first, what to skip, and which parts create avoidable problems.
Firmware symptom map for Arduino and ESP32 projects Firmware symptom map Wrong baud rate, blocking code, pin conflicts, library mismatch, and serial debug flow.

Use it when

Your project works once, then becomes impossible to trust.

If the issue changes every time you touch a wire, add a relay, connect WiFi, or move from USB to battery, the pack gives you a fixed order of checks.
