Customer:
Does the InkPlate 6 have a pin that can power a WS2812B Smart LED Stick10? If so, which pin would it be?
Ima li InkPlate6 pin s kojeg bi bilo moguce napajati Smart LED WS2812B Stick10?
Ako ima, mozete li reci koji bi to bio?

Soldered Support:
The WS2812B Stick10 requires 5V to operate. On the InkPlate 6, you can connect power to the VIN pin, which carries voltage from either USB or the battery depending on how you power the board. If the device is powered by battery, you may experience issues with the WS2812B LEDs when the battery voltage drops below a certain level.
You can also try connecting the Data pin directly to an ESP32 pin, but it may not work correctly. In that case, you will need a logic level converter to convert the voltage level from 3.3V to the VIN pin voltage level. WS2812B LEDs have a logic “1” voltage threshold very close to 3.3V, and depending on the supply voltage (which can vary between 5V and 4.5V), they sometimes work when the Data pin is connected directly to the ESP32 microcontroller, and sometimes they don’t work properly and require a logic level converter.
Smart LED WS2812B Stick10 za rad treba 5V. Na Inkplate6 možete spojiti napajanje na VIN pin. Na njemu je napon s USB-a ili s baterije ovisno kako napajate pločicu. Ako se uređaj napaja s baterije možete imati problema s WS2812B LED kada napon baterije padne ispod određene razine.
Također možete probati spojiti Data pin direktno na ESP32 pin, ali možda neće raditi ispravno. Tada će vam trebati i logic level converter za pretvaranje naponske razine od 3.3V na naponsku razinu VIN pina. WS2812B ledice imaju naponski prag za logičku “1” na naponu koji je jako blizu 3.3V i ovisno o naponu napajanja (može malo varirati od 5 do 4.5V) nekada rade kada se na Data pin spoji direktno sa ESP32 mikrokontrolera, a nekada ne rade ispravno te onda treba koristiti logic level konverter.
Customer:
Does the microcontroller have the ability to detect whether USB (as an external power source) is connected?
Hvala na odgovoru.
Ima li mikrokontroler mogucnost detektirati je li USB (kao vanjski izvor) spojen?

Soldered Support:
The microcontroller does not have USB detection capability. On the InkPlate there are free pins from the GPIO expander or from the ESP32, and it is possible to create a simple voltage divider and connect it to the microcontroller to monitor the voltage on the USB line and thereby determine when power is supplied via USB and when it is not.
Mikrokontroler nema mogućnost detekcije USB-a. Na Inkplate-u postoje slobodni pinovi od GPIO expandera ili od ESP32 te je moguće složiti jednostavno naponsko djelilo te povezati na mikrokontroler kako bi se pratio napon na USB-u te prema tome znalo kada je spojeno napajanje putem USB-a, a kada nije spojeno.
