STM32 OpenSource Multimeter - an open source multimeter suitable for DIY entry

Overview

An open source multimeter design based on STM32F1/F3, with dual-range V/I, RMS measurement, continuity, component testing and other functions. The author has made all design files open source, which is very suitable for DIY entry.
Main parameters:
Voltage measurement: ±60 V, ±6 V, ±600 mV, ±60 m range, with DC or RMS data acquisition Current measurement: ±250 or ±2500 mA range, also using DC or RMS to measure voltage and Current and display products i.e. power measurements Continuity and display of resistance and voltage drop Can perform simple component testing Frequency measurements up to 10 MHz
