Its quite good, even resolved 100khz of 50ma square current well. magnetic field probing is a bit unstable. Overall impressed with the current probe.

Super! So etwas wollte ich schon immer dass man auf einer Leiterplatte den Strom messen kann. top verpackt. Ich bin sehr zufrieden. EU Adapter war sogar auch dabei !

Sandeep Kumar isthat useful to measure currents with a shunt resistor ?

Good low signal amplifier for the oscilloscope probes; not cheap but well constructed. Bandwidth is only 10 Mhz but anyway useful in many scenarios. It came partially charged, so I had to charge it before use. It makes a little noise when in operation (probably a switchong converter inside for dual voltage or so). I will perform some tests with it when possible (linearity, rise time, noise level,...). Very well packaged and presented; BNC connection cable imcluded.

Sandeep Kumar Howdid you measure the freq accuracy, you had even more accurate clock source?

A brilliant addition to the test bench! Caution though: It states that power supply is 7VDC to 13VDC, however above about 10VDC the component U1 gets *very* hot! I ran my device at 7.5 volts. Warm-up time from cold was less than 300 seconds. 10MHz Frequency accuracy, measured straight after receipt appears to be around 0.03Hz (1 cycle every 30 seconds!) but is adjustable. I was unable to measure phase noise, so that will be future challenge. I did not check the TTL output (I don't intend to use that feature). The supplied short cable uses very thin conductors and I will replace it. Bottom line? Excellent !

Works well, even though schematic help is not provided. We have to figure out pins through multimeter. Can be programmed by uart interface.

Sandeep Kumar canwe control the board from arduino or esp32 after updating the firmware ?

BG483950210 09/02/2026
You have to update the firmware to the MakerBase firmware for things to work. Hall sensors work perfectly, all other functions were okay. I cannot get SPI encoders to work at all. I’m trying my best

The dial indicator arrived quickly and packed neatly. It was quite small and useful with the pivot needle that has a ruby tip.

The lcr meter arrived quickly and was neatly packed. The readings were quite accurate, though the inductance readings can not go below 0.1 micro henries. worth buying it.
