Capacitors C8/C9 no voltage specified

Open GreyHatUser opened this issue 10 months ago • 2 comments

I built the entire thing, i noticed first time i ordered the capacitors wrong as i bought 10uf 10v capacitors, when in the schematic specifies 2.2uf, now, when i powered the device on both (of the wrong capacitors) got burnt, i wanted to make a new order for the right capacitors for C8/C9, but there is no voltage specified, does anyone know what voltage should they be?

Still, trying to connect the device with no C8/C9 capacitors wich should theoretically work, the tool doesnt get detected by the pc, i changed the USB to UART chip in case it was broken but still nothing. Are the C8/C9 100% necessary?

В gerber файлах указано C8/C9 Tant 2.2uf

Я временно заменил на керамические конденсаторы 2.2uf и вроде всё работает. Компьютер видет esp32 и даже записывает прошивку, но не включается. Возможно дело в прошивке, пока не разобрался.
