Create A Low-cost- High-accuracy Lcr Meter With An Stm32 Mcu May 2026

But what if you could build one with for the cost of a pizza?

Apply a Discrete Fourier Transform (DFT) at the exact test frequency. This rejects noise and harmonics. Create A Low-Cost- High-Accuracy LCR Meter With An STM32 MCU

Trigger ADC with a timer at, say, 64× the sine frequency. Use dual regular+injected mode to sample two channels with known delay. But what if you could build one with for the cost of a pizza
