DP2 DP2F USB Adjustable Power Module DC‑DC Step‑Up Step‑Down Converter CC CV 5V To 1‑30V 2A Voltage Regulator Board With Digital Display

DP2 / DP2F USB Adjustable DC‑DC Power Supply Module

📌 Product Overview The DP2 and DP2F are digital USB adjustable step‑up & step‑down power modules. Powered by standard USB interface, they convert fixed 5V input into continuously adjustable DC output voltage. Equipped with a 4‑digit digital tube display, it can real‑time show the output voltage value. Two precision potentiometers are used for constant‑voltage (CV) and constant‑current (CC) setting separately. Multiple versions are available: bare PCB low‑configuration version, high‑configuration version with plastic housing, and DP2F quick‑charge trigger version. It features high conversion efficiency, stable output and compact size, widely used for laboratory power test, battery charging, electronic maintenance and DIY embedded projects. ✨ Core Features

• USB input, support 5V power supply from adapter, power bank or PC
• Buck‑boost topology, adjustable DC output voltage
• 4‑digit digital display for intuitive voltage reading
• Independent precision potentiometers for CV constant voltage and CC constant‑current adjustment
• Multiple optional variants: DP2 bare board, DP2 high‑config with case, DP2F fast‑charge trigger model
• High‑quality filter capacitors for smooth and low‑ripple output
• Compact PCB layout, convenient for desktop debugging and portable use
• Over‑current and short‑circuit protection design for safe operation
