Red ATX 24-pin breakout board with acrylic case kit, 60 by 99 mm

JMT

JMT ATX 24-Pin Breakout Board with Acrylic Case Kit

SKU CH-8SEY-EJ3EC

Breaks out a 24-pin ATX supply into adjustable 1.8–10.8 V plus fixed 3.3 V, 5 V and 12 V rails with screw terminals, a three-digit 12 V readout and USB QC 2.0/3.0 ports, all housed in an acrylic case

  • Chassis TypeDesktop
  • Adjustable voltage from 1.8 to 10.8 V for flexible prototyping
  • Fixed 3.3 V, 5 V and 12 V rails power common boards directly
  • Three-digit LED shows 12 V output in real time
  • Screw terminals match each voltage rail for secure wiring
  • Acrylic case kit encloses the breakout board for bench use

ATX 24-Pin Breakout Board with Adjustable Voltage

The JMT breakout board converts a standard ATX 24-pin power supply into a bench-top source with fixed 3.3 V, 5 V and 12 V rails plus an adjustable 1.8 V to 10.8 V output controlled by a knob. It is aimed at makers, embedded developers and hobbyists who need clean low-voltage rails for microcontroller boards, single-board computers or small motor drives without building a custom supply.

Acrylic Case Kit and Real-Time 12 V Display

The bundled acrylic enclosure protects the PCB and keeps screw terminals accessible while the three-digit LED panel shows the 12 V rail voltage in real time. A twelve-port USB 2.0 hub adds convenient 5 V charging or data connections for devices such as Raspberry Pi, Banana Pi or Tinker Board, and Quick Charge 2.0 and 3.0 support enables faster charging for compatible gadgets.

Compact Red ABS Board with Screw Terminals

The 60 mm by 99 mm red ABS board mounts inside the acrylic case and presents every output on clearly labelled screw terminals for secure, tool-free wiring. Fixed 3.3 V suits STM32 and wireless modules, 5 V covers USB peripherals and single-board computers, 9 V drives small motors or display modules, and 12 V handles loads under 24 W such as LED strips or vehicle accessories. Builders needing higher currents, additional fixed rails or a fully enclosed metal chassis will need a different solution.

Questions sur cet article

Will the adjustable voltage potentiometer on the ATX breakout board wear out or need replacement after extended use?

The adjustable voltage knob controls the 1.8V to 10.8V output range; potentiometers can develop contact resistance over time, so periodic verification of the three-digit LED voltage readout is advisable.

What is the first power limit reached when running the board continuously at 12 V output?

The 12 V rail is rated for devices drawing less than 24 W, so sustained loads above that threshold will hit the board's output limit before the ATX supply itself.

How much heat does the acrylic case kit dissipate when the board runs all day at 5 V or 12 V?

The ABS and acrylic enclosure has no active cooling; heat from the onboard regulation for 3.3 V, 5 V, 12 V and the adjustable 1.8 V to 10.8 V rails is passively dissipated through the case panels.
