“A multimeter, based on the STM32F103, which can measure voltage, current and power, both bipolar and in DC and true RMS. In short, I needed more multimeters at my lab. You can get these cheap Chinese “multimeters” from Ebay, but …
Content for MCP6072
The MCP6072 operational amplifier (op amps) has a low input offset voltage (±150 µV, maximum) and rail-to-rail input and output operation. The MCP6072 is unity gain stable and has a gain bandwidth product of 1.2 MHz (typical). This device operates with a single supply voltage as low as 1.8V, while drawing low quiescent current per amplifier (110 µA, typical). These features make the MCP6072 well suited for single-supply, high precision, battery-powered applications.
