Customer:
What is the maximum voltage that can be connected to the BAT input on the Dasduino CONNECTPLUS microcontroller? Would it be 18V since your voltage regulator uses the TPS7A2633DRVR component?

koji je maksimalni napon koji se može priključiti na BAT ulaz kod Dasduino CONNECTPLUS mikrokontrolera? Bi li to bilo 18V pošto Vaš regulator napona koristi TPS7A2633DRVR komponentu?

Soldered Support:
The maximum voltage on the VBAT pin is 4.2 V. The charger output on the board is connected to the VBAT pin, so connecting a higher voltage would damage the charger. Although the voltage regulator on the board has a maximum input voltage of 18 V, there are other components connected to that line that would be damaged by voltages higher than 5 V (specifically a WS2812B LED is connected).

Maximalni napon na VBAT pinu je 4.2 V. Na VBAT pin je spojen i izlaz punjača koji se nalazi na pločici te spajanjem većeg napona spalili bi punjač. Regulator koji se nalazi na pločici ima maximalni ulazni napon od 18 V, ali ima još komponenti koje su spojene na tom vodu tako da bi spajanjem većeg napona od 5 V spalili te komponente (konkretno spojena je WS2812B LED-ica).
