Handheld Mini Oscilloscope for Bench and Field
Probe live circuits, debug waveforms, and diagnose automotive signals without being tethered to a bench scope. Compact enough to fit in a toolbox, capable enough to read PWM, serial, and analog signals in the field. Built for makers and techs who need real measurements away from the desk.
Project idea: Wire it to your car's crankshaft position sensor output and capture the actual waveform at idle versus cranking to diagnose intermittent no-start conditions without pulling codes.
Key Features
- Handheld form factor with built-in display, no laptop or external screen required
- Auto-trigger and auto-measurement modes for fast waveform capture
- Reads frequency, duty cycle, voltage amplitude, and period directly on screen
- Suitable for automotive ECU signals, sensor outputs, and embedded PWM lines
- Single-channel input with adjustable timebase and voltage scaling
- Battery-powered for portable use on vehicles or remote boards
- Ships from US warehouse, typically 3-7 business day delivery
Frequently Asked Questions
Can this read I2C or UART signals for embedded debugging?
It will display the raw waveform of those signals, so you can check voltage levels and timing. It does not decode serial protocols. For protocol decoding you'd want a logic analyzer alongside this.
What voltage range can it safely measure?
Check your specific unit's datasheet for maximum input voltage before probing mains or high-voltage automotive circuits. Most handheld scopes in this class are rated for low-voltage signal work, typically under 40V DC. Do not probe directly off ignition coil primary without an attenuator probe.
Is the battery rechargeable or does it take AA cells?
This unit uses a rechargeable internal battery. Charge via the included cable before first use. Runtime varies with display brightness and input activity, generally 2 to 4 hours of active probing.
