Hi to all,

I realized my first pcb using a STM32F030K6 MCU. The project is a very simple one, that is no external oscillator, only two leds and a usart interface.I can regularly download the program using ''flash loader demonstrator'' and leds blink as they should do.

The problem is power consumption, that is 500 mA and, in fact, I needed to add a heath sink.

I tried with another mcu, but the result was the same. I aspected no more tahn 20 mA and I do not understand where is the problem

I looked on internet, but projects I found were similar to mine.

Someone can help me?

Thank youu

Freya

Kind of screams of a short or conduction path.
