Im using STM32F103C8T6 with sl4432 as small radio beacon. It's working fine, but range much shorter than suppose to be. Sl4432 require max 85 mAh for 20dbm transmit, but how much STM32F103C8T6 3.3v pin can give at max? I can't find that info in datasheet and it's not GPIO pin anyway.
To be more specific, I power up STM32F103C8T6 from blue circle. And power up my sl4432 from green circle.
