USB Logic Analyzer DKARDU JK-US-155 8CH 24MHz with Mini USB Cable

Description

Product Overview

The DKARDU USB Logic Analyzer JK-US-155 is a compact, high‑performance instrument designed for developers, engineers, and hobbyists who need precise insight into digital communication signals. Featuring eight independent channels, the analyzer can sample at rates up to 24 MHz, providing the bandwidth required to capture fast UART, SPI, and I²C transactions without missing critical edges. The device is fully compatible with the popular Saleae Logic software, allowing users to visualize waveforms, decode protocols, and export data for further analysis. Its robust hardware includes a mini‑USB interface for fast data transfer to a host PC, and a set of six‑color Dupont test hooks that simplify connection to breadboards, development kits, and custom circuits. The analyzer’s voltage tolerance ranges from 0 V to 5.5 V, with a 1.5 V threshold that reliably distinguishes logical low and high states, ensuring accurate interpretation across a variety of logic families.

In addition to its core sampling capabilities, the JK‑US‑155 offers built‑in automatic protocol analysis. Users can enable UART, SPI, or I²C decoding with a single click, and the software will present decoded bytes, timing information, and error flags in an easy‑to‑read format. This reduces the time spent manually interpreting raw waveforms and accelerates debugging cycles. The device’s compact form factor—measuring just over 5 × 3 × 1 inches and weighing under 100 g—makes it portable enough to accompany field work or be stored alongside other test equipment without clutter. All components are built to withstand the rigors of daily use, from the sturdy USB connector to the color‑coded test hooks that resist wear and maintain reliable contact over thousands of insertion cycles.

Usage

Designed with versatility in mind, the DKARDU analyzer fits seamlessly into a wide range of development environments. Whether you are prototyping a new Arduino shield, validating FPGA I/O timing, or troubleshooting a custom PCB, the eight‑channel capability lets you monitor multiple signals simultaneously, capturing the interplay between clock, data, and control lines. The included mini‑USB cable provides a direct, high‑speed link to a laptop or desktop, enabling real‑time streaming of captured data at the full 24 MHz rate. For hobbyists working on hobbyist projects, the six‑color Dupont hooks make it trivial to connect to standard 0.1 in header pins, allowing quick plug‑and‑play testing without soldering.

In educational settings, the analyzer serves as an excellent teaching tool for illustrating digital communication concepts. Instructors can demonstrate how UART frames are constructed, how SPI master‑slave relationships operate, or how I²C arbitration resolves conflicts, all with live waveforms displayed on the screen. For professional engineers, the device’s ability to switch sampling rates—from 500 kHz up to 24 MHz—provides the flexibility to balance resolution and memory usage, ensuring that long capture windows are possible when lower rates are sufficient, while high‑speed bursts capture transient glitches when needed. The analyzer also integrates smoothly into automated test rigs, where scripts can trigger captures, retrieve data, and compare results against expected patterns, supporting continuous integration workflows for hardware development.

FAQ

What operating systems are supported by the Saleae Logic software?

The software runs on Windows 10 or later, macOS 10.13 (High Sierra) and newer, and popular Linux distributions such as Ubuntu 18.04+. No additional drivers are required for the mini‑USB connection.

Can the analyzer capture analog signals or only digital?

This model is optimized for digital logic analysis. It measures voltage levels between 0 V and 5.5 V and interprets them as logical low or high. For analog waveform capture, a dedicated oscilloscope would be more appropriate.

How do I change the sampling rate for a specific capture?

Within the Saleae Logic application, select the desired channel group, then choose the sampling rate from the drop‑down menu. Options range from 500 kHz up to 24 MHz, allowing you to balance resolution and memory usage based on the needs of your test.

Is the device compatible with other logic analysis software?

While the hardware is designed for optimal performance with Saleae Logic, it also works with open‑source tools such as sigrok and PulseView, provided the appropriate drivers are installed.

What is included in the package?

The package contains the JK‑US‑155 analyzer, a mini‑USB cable, a set of six‑color Dupont test hooks, a user manual, and a USB‑type‑C to USB‑type‑A adapter for compatibility with older computers.
