Hks-va028-v2.0

Since HKS-VA028-V2.0 is not a publicly listed consumer-friendly part number on HKS’s global or Japanese primary catalogs (as of 2025), it is strongly advised that you:

Note: If this identifier appears on a software file (e.g., .bin, .hex, or .pdf), treat it as a proprietary revision; do not attempt to flash or install it without explicit matching hardware and HKS guidance.

HKS-VA028-V2.0 is a specific hardware revision for a digital DC voltmeter and ammeter

module. This compact panel meter is widely used by electronics hobbyists and engineers to monitor real-time voltage and current in power supplies, battery chargers, and DIY solar setups. Overview of the HKS-VA028-V2.0 The "0.28" in the model name refers to the 0.28-inch LED display hks-va028-v2.0

. These modules are popular because they integrate two essential measurements into a single, space-saving unit. The V2.0 revision often includes minor improvements in power efficiency or measurement stability over previous versions. Core Specifications

While specific tolerances can vary by manufacturer, standard specs for this module include: Voltage Range: 0–100V DC (though some variants support up to 500V). Current Range: Standard models handle up to Display Style: Dual 3-digit LED (usually for voltage and for current). Power Supply: Requires its own operating voltage (usually DC 4–30V ) to power the LEDs. Generally around , which is sufficient for most hobbyist projects. Key Features Built-in Shunt:

For the 10A version, the current-sensing shunt is typically built directly into the PCB, meaning you don't need a bulky external component. Calibration Potentiometers:

Most V2.0 boards feature two small trim pots on the back, allowing you to fine-tune the voltage and current readings against a professional multimeter. Simple Wiring: Maintenance and Troubleshooting

It usually comes with two sets of wires—a thin set for power and a thick set for measuring the load current. Common Use Cases Bench Power Supplies:

Adding a digital readout to a custom-built or older analog power supply. Battery Monitoring:

Keeping an eye on the discharge rate and voltage levels of Li-Po or Lead-Acid batteries in RVs or e-bikes. Solar Systems:

Monitoring the output of small-scale solar panels before they reach a charge controller. Wiring Safety Tip When installing the HKS-VA028-V2.0, ensure the thick black wire Since HKS-VA028-V2

The HKS interface is menu-driven. Here is how to navigate the tuning screen effectively.

In the ever-evolving world of automotive performance engineering, few components command as much respect as a precision-engineered wastegate actuator. For enthusiasts of forced induction systems—particularly those wielding turbocharged Japanese machines—the part number HKS-VA028-V2.0 has rapidly become a reference point for reliability and boost control. But what exactly is this component? Why is the “V2.0” suffix so critical? And should you upgrade to it immediately?

This article deconstructs everything you need to know about the HKS-VA028-V2.0, from technical specifications and installation nuances to real-world dyno results and comparative analysis with its predecessor.

The HKS-VA028-V2.0 requires surprisingly little upkeep. HKS recommends:

Most cheap fuel controllers on the market are "piggybacks" that simply trick the ECU by altering the airflow signal across the entire rev range. The VA028 is different.
