Thomas Hornschuh Posted April 1, 2017 Report Share Posted April 1, 2017 Hi, I'm currently conneting an ESP8266 WiFi module to the Papilo Pro. I tried to find a specification about the max. current the 3,3V rail can deliver. According to the data sheet of the LTC3419 converter it can deliver 600mA. My measurements show that the ESP8266 draws around 190mA average current. I'm aware that also the USB port itself is limited, but this is not my question at the moment. I think the SPARTAN-& draws most of its current at the 1,2V rail, so the 3,3V rail must power the other chips (SDRAM, Flash, FTDI), so I think the addtional 200mA is ok.
