This Mega328 LCR meter works quite well for the price. It's not something I would rely on for accuracy nor precision, but it gets the job done in a pinch and is good enough for hobbyist and educational use.Dedicated multimeters capable of LCR readings tend to be very expensive, so this fills that gap on a hobbyist's test and metering toolbox.I don't have sensitive enough tools to do LCR readings that I could compare these readings to, but a cursory check from known parts has readings that match what's expected. The transistor tester works also.

At a first glance, I was somewhat disappointed in an "uncooked" product that comes as a board with LCD screen taped to it. However, after playing with it for 10 minutes, I declare it to be a very useful tool, for testing transistors and diodes. It auto-detects types and pinouts and measures major parameters. No multimeter can match it. It can also test capacitors and resistors.The tool is built around Atmega328. It is an older version of hardware and there is open-source firmware for it. If you are into electronics, you'll find this tool very useful. You will also $20 for the bare board expensive. Similar tools can be sourced from Aliexpress for around $14, complete with case.
