Mini OLED USB C Power Analyzer

USB-C inline power analyzer with OLED display showing real-time voltage, current, wattage, and peak readings.

USB-C input
USB Type-C source/charger side connection for the KWS-2301C tester; manual states the tester measures charging voltage from 4-30 V and current from 0-12 A.
Type · powerVoltage · 4-30 V measurement range per KWS-2301C product manual
USB-C output
USB Type-C load/device side connection; passes the charging path through the tester so voltage, current, power, capacity, energy, and current direction can be displayed.

Breadboards

Solderless options run from 830- and 400-point boards to 4.5×3.5 cm minis and self-adhesive translucent boards. Adafruit Perma-Proto PCBs copy breadboard rail layout onto solderable copper, so a working layout transfers directly. SMT adapters bridge QFN, TQFP and SSOP parts to 2.54 mm.
