PokIt Review: Can This Tiny Device Really Do It All? The world of test and measurement equipment has traditionally been dominated by bulky, expensive benchtop units. For hobbyists, makers, and field engineers, carrying a separate multimeter, oscilloscope, and data logger is a heavy and costly burden. Enter PokIt, a device that promises to shrink an entire electronics lab into a single tool small enough to fit on your keychain. But can a gadget this tiny truly deliver full-scale performance? Here is our comprehensive review. What Is PokIt?
PokIt is an ultra-portable, wireless measurement tool that connects to your smartphone or tablet via Bluetooth. It integrates three essential engineering instruments into one coin-sized chassis:
Digital Multimeter (DMM): Measures voltage, current, resistance, and temperature.
Digital Oscilloscope: Captures and displays voltage waveforms over time.
Data Logger: Records parameters continuously over extended periods.
By offloading the screen and processing power to your smartphone app, the hardware remains incredibly compact and lightweight. Design and Portability
The first thing you notice about PokIt is its radical design. It features a circular, integrated body with built-in leads that wrap neatly around the device.
The Leads: The retractable mechanism is highly intuitive, though the wires are understandably thin to maintain the small form factor.
The Clips: It comes with attachable alligator clips that press directly onto the probe tips, allowing for hands-free testing.
Portability: It easily fits into a pocket or hooks onto a keychain, making it the most portable multi-tool on the market. Performance as a Multimeter
For daily troubleshooting, the DMM function is where most users will spend their time.
Accuracy: PokIt holds its own against standard entry-level multimeters for low-voltage electronics. It reads DC/AC voltage, AC/DC current, resistance, and continuity with minimal latency.
Safety Limits: It is crucial to note that PokIt is designed for low-voltage applications (typically up to 60V DC / 42V AC and 2A). It is not a replacement for a CAT III/IV bench meter and should never be used on household mains power.
Usability: The smartphone app displays readings clearly with large, readable digits, making it easier to see than a tiny LCD screen on a cheap traditional meter. Performance as an Oscilloscope
Shifting to the oscilloscope function reveals where the device truly innovates—and where it hits its physical limits.
The Good: It features a single-channel sampling interface that is perfect for viewing audio signals, slow communication protocols (like I2C or UART), and basic PWM signals. The touch-screen app allows you to pinch-to-zoom on waveforms effortlessly.
The Catch: With a limited bandwidth and sampling rate, it cannot capture high-speed digital signals or RF frequencies. It is excellent for basic debugging but inadequate for complex, high-speed circuit design. Performance as a Data Logger
The data logging feature is a massive bonus for environmental testing and long-term project monitoring.
Standalone Operation: You can set the parameters via the app, leave PokIt attached to a circuit or battery, and walk away. It logs data internally for days or weeks using its onboard battery.
Data Export: Once you reconnect via Bluetooth, the app downloads the logged data and allows you to export it as a CSV file for analysis in Excel or MATLAB. The App Experience
Because PokIt has no screen, the software dictates the entire user experience. Fortunately, the companion app is polished and modern. The Bluetooth connection is stable, pairing takes seconds, and switching between the multimeter, scope, and logger views requires just a few taps. It bridges the gap between complex engineering concepts and a clean consumer-tech interface. Verdict: Can It Really Do It All?
PokIt cannot replace a dedicated laboratory bench setup. It lacks the high bandwidth of a standalone oscilloscope and the safety ratings required for high-voltage electrical work.
However, asking it to replace a $500 bench meter misses the point. PokIt succeeds wildly at what it was actually built to do: providing a highly accurate, incredibly versatile “first-response” tool for your pocket. If you are an Arduino enthusiast, a drone builder, an automotive hobbyist, or a field technician who needs to make quick diagnostics without hauling a heavy toolkit, PokIt is an absolute game-changer.
