JMT ATX 24-Pin Breakout Board 12-Port USB 2.0 QC 2.0/3.0 Acrylic Case Kit

SKU CH-C1KH-F2RQP

An ATX 24-pin breakout board with 12 USB 2.0 ports, QC 2.0/3.0 support, adjustable 1.8-10.8 V output and a 3-digit LED voltage display, housed in an acrylic case kit

  • Chassis TypeDesktop
  • Adjustable 1.8 V–10.8 V output powers diverse prototypes
  • Fixed 3.3 V, 5 V and 12 V rails run SBCs and motors
  • Real-time three-digit LED shows 12 V level at a glance
  • Twelve USB 2.0 ports with QC 2.0/3.0 charge phones and tablets
  • Acrylic case kit protects the board while keeping terminals accessible

ATX 24-Pin Breakout Board with Adjustable Output

This board converts a standard ATX 24-pin supply into multiple fixed and adjustable rails. It provides 3.3 V, 5 V, 12 V and a 1.8 V to 10.8 V adjustable output for bench testing and embedded projects. The acrylic case kit encloses the PCB for safer handling on a workbench. Makers and engineers who need flexible voltages from a single ATX unit will find it useful.

Sustained Load Behaviour and Voltage Monitoring

Fixed rails deliver 3.3 V, 5 V and 12 V continuously within the limits of the host power supply. The adjustable rail spans 1.8 V to 10.8 V and is set by a front-panel knob. A three-digit LED shows the 12 V rail voltage in real time so drift can be spotted during long runs. Loads above 24 W on the 12 V rail are not supported by the design.

Acrylic Enclosure and Connection Layout

The red ABS board measures 60 mm by 99 mm and ships with an acrylic case kit that covers the solder side. Twelve USB 2.0 ports provide QC 2.0 and QC 3.0 charging alongside the screw-terminal voltage outputs. Each output maps to its own terminal block for tidy wiring. Users who require higher current than the screw terminals allow or need more than twelve USB ports should look elsewhere.

Perguntas sobre este artigo

How much heat does the ATX breakout board generate when running all day?

The board draws power directly from the ATX 24-pin supply and provides fixed 3.3 V, 5 V and 12 V rails plus an adjustable 1.8–10.8 V output; total dissipation depends on the load you connect to the screw terminals and the 12 USB 2.0 ports.

What must I already own for this kit to work?

You need a standard ATX power supply with a 24-pin connector to feed the breakout board; the acrylic case and screw terminals are included.

Will the adjustable 1.8–10.8 V rail work safely with my older 5 V Arduino projects?

Yes — set the knob to 5 V (or use the dedicated 5 V fixed rail) and the board will supply up to the PSU's rated current for legacy 5 V microcontrollers.
