PSoC5 MCU already has boost converter component built-in, so one can use e.g. 1.5V battery to power the MCU at e.g. 3.3V. Problem is rf noise created within the chip, affecting ADCs, DACs and all ...

We all know that solderless breadboards have their limitations. All that stray capacitance can play hell with circuits, especially high-speed stuff, but they’re so darn useful that avoiding t… ...
