Customer:
On the Dasduino CORE board, is the BAT pin the same as the VIN pin? What is the maximum input voltage on that pin? Can a 9V battery be connected to it? Also, what are the maximum current and voltage specifications for the JST battery connector?

Poštovani, na Dasduino CORE uređaju, BAT pin je VIN pin zar ne? Koliki je maksimalni ulazni napon na tom pinu? Smije li se na taj pin spojiti 9V baterija? Također, kolika je maksimalna struja i napon na JST konektoru za bateriju? L.P. [name removed]

Soldered Support:
The BAT pin is not the same as the VIN pin. The JST connector is designed exclusively for Li-ion batteries with a nominal voltage of 3.7V. When you connect a Li-ion battery to the JST connector, the voltage at the BAT pin will be the battery voltage. When the battery is connected to the JST connector and USB is plugged in, the battery will charge because the board has a Li-ion battery charger circuit.
There is a VCC pin where you can connect a maximum of 5V. If you connect USB, that pin will automatically have 5V. Connecting a 9V battery is not permitted in this case.

BAT pin nije VIN pin te je JST konektor predviđen samo Li-ion bateriju čiji je nominalni napon 3.7V što znači da kada na JST konektor spojite Li-ion bateriju na pinu BAT će biti napon baterije. Kada uključite bateriju u JST konektor te spojite USB, baterija će vam se puniti jer na pločici postoji punjač za Li-ion baterije.
Postoji pin VCC gdje smijete maksimalno spojiti 5V no ako spojite USB automatski će te na tom pinu imati 5V, također nije dopušteno u vašem slučaju spajati bateriju od 9V.
U prilogu Vam šaljem shemu tiskane ploče.
