Pros & Cons
Pros
- No PC software needed — runs via USB-C as a USB scope directly
- 50MHz bandwidth sufficient for most digital signal debugging (I2C, SPI, UART)
- Compact enough to keep on the bench without dedicated scope space
- Includes 2 probes for comparing clock vs data simultaneously
- Works on Windows, Mac, and Linux without drivers
- Adds real capability at an impulse-buy price
Cons
- Not a replacement for a real oscilloscope — sample depth and trigger options limited
- USB bandwidth means slower waveform update rate than dedicated hardware
- No external trigger input
- Software UI is functional but not polished

Our Verdict
The FNIRSI P02 is the best 'good enough' USB scope for a soldering bench. If you debug Arduino/ESP firmware, verify PWM signals, or check I2C traffic, it saves hours of print-statement debugging. Not a standalone scope replacement — a perfect $50 complement.
