GCON LM317 DIY Kit Adjustable Step-Down Module 110V 1.25V-12.5V gender changer

SKU CH-VFF8-NGDSK

A DIY kit with an LM317 regulator that steps 110 V down to 1.25–12.5 V and adds a pulse generator, logic probe and continuity buzzer on a 7.3 × 6.8 cm board

  • Adjustable 1.25V-12.5V output from 110V input
  • LM317 regulator enables DIY step-down power supply
  • Built-in signal generator provides adjustable pulse output
  • Logic pen function simplifies circuit logic-level testing
  • Integrated buzzer checks wire continuity and low-frequency signals

Adjustable Step-Down Module Kit

This GCON LM317 DIY kit provides an adjustable step-down power supply module that converts 110V input to a regulated output between 1.25V and 12.5V. It is aimed at electronics hobbyists and technicians who need a versatile voltage regulation solution for prototyping or repair tasks.

PCB Build and Integrated Test Functions

The kit includes a PCB board measuring 7.3 x 6.8cm housed within a shell sized 11 x 6.9 x 41.5cm. It features a one-way adjustable signal generator for pulse signals, a logical pen function for testing circuit logic levels, and a buzzer for wire continuity and low-frequency signal detection.

Passive Operation and Power Characteristics

The module operates without active cooling, relying on the LM317 regulator's inherent thermal management for the supported voltage range. Noise is limited to the buzzer used during testing functions. Power draw depends on the connected load and the configured output voltage within the 1.25V to 12.5V range.

Questions about this item

What input voltage does the LM317 step-down module accept?

The module accepts a 110 V input and regulates it down to an adjustable 1.25 V to 12.5 V output range.

How much space does the assembled shell occupy?

The enclosure measures 11 cm long, 6.9 cm wide and 41.5 cm high, so allow that clearance in your project box.

Which step is most often missed when soldering this kit?

Builders frequently forget to fit the logic-pen probe and buzzer leads before closing the shell, leaving the test functions inaccessible.
