Breadboard Power Studio — 4-Rail Logged PSU

Description

Power every rail like you mean it. Four isolated outputs feed your breadboard while an ESP32-C3 logs per-rail current draw to a live web dashboard — spot a brown-out before it ruins your afternoon.

What is in the box

• ESP32-C3 SuperMini development board (pre-flashed)
• Dual breadboard power supply modules (4 isolated rails total)
• INA219-class current-sense breakouts (per-rail logging)
• 830-point solderless breadboard
• Barrel-jack adapter + USB-C cable + jumper wires
• Step-by-step build guide

Plug in 9-12V DC or USB, snap the modules onto the breadboard rails, and watch every milliamp in real time. Wiring diagram and calibration steps are in the guide.
