Shizuku USB MultiMeter


Shizuku USB Multimeter is a all-in-one test equipment designed for USB surrounded devices. Main features can be divided into several parts: Voltage&Current Monitoring, Fast-charge trigger, Capacity/Energy Accumulation, Data Logging, User Programmable Design, Electronic Load (With module SM-LD-00). It's suitable for charger/powerbank tests, factory multi-production and products development.

Specialities compared to old series(Kotomi)

If you've never used the old series devices, skip this section.

1. Provided lua APIs for user programming, to custom your own features or batch tests.

2. Supports extension module (SM-LD-00 is provided so far, modules with other features are under development).

3. More powerful PC software.

4. Internal 12MBytes user data space, for user program saving(Your program can also write files to this space), data logging.

5. Able to view ripple graph of VBUS with internal 3.2Msps ADC.

6. Larger screen(2.0' 128*160)

7. (Super)VOOC/DASH extra signal line is now passed through, enabling direct measurement of devices running (Super)VOOC/DASH protocols.

8. A buzzer is added to improve user experience.

9. A gravity sensor is added to rotate the screen automatically.

11. (Super)VOOC/DASH cable reader.

12. USB3.1 partially supported.
