  1. ha! I just wanted to add, as a follow up of my original post, that is exactly what I did, I bought a cheap noname phone charger of 2amps and that was enough to power the board (connected directly to the expansion header), power relay and wifi dongle, granted as explained before my use case is really simple and the board is waiting idle most of the time. Up time: 57 days Last downtime was due to power outage, I wouldn't know if that power supply is insufficient on heavy load but I'll keep it in mind. I did have some wifi disconnections but those were because of the driv
  2. I guess my laptop is the same, when I connect my phone it doesn't complain about slow charging as it does with other usb ports, but I wasn't sure because of those USB specifications and didn't wanted to waste another power supply to find out it was something wrong with my wiring or somewhere else, but that cleared my doubts. I'll try that minimal consumption config and if that doesn't work I'll throw a higher power supply into it, sadly I dont have a USB-TLL adapter, I saw it when ordering my parts but I thought I wouldn't need it... oh well that's a lesson for me.
  3. I've got an OPi Zero v1.1 for a home project, It was supposed to be something very simple, connect the board to wifi, make a web app for external control and switch a power relay, I did finished it and everything was working fine but I had sudden disconnections and one day just didn't wanted to reconnect, I've read before about how this board has an horrible wifi chip and trying to avoid further headaches I went and bought an USB WiFi dongle TP-LINK_TL-WN725N, I got it today and connected it to the board using its 13 pin header, then I powered it on via micro usb and worked right out the box,
