What kind of battery can be connected directly to this board?

the intention is to use a one cell lipo battery

Will this board work with TTN V3?

Yes，this board can work with TTN V3.

Can a LDO regulator output go to the 3.3 volt pin?

According to the schematic, the unit uses a ME6211 LDO between the 5v and 3.3v, so I say yes, you can. Looks like you won't be able to charge the battery, though. FYI, there is a trick to use the SD card as well. You need to manually deselect the LoRa chip (18 HIGH) then manually select the card reader (13 LOW). Seems you can't use both at the same time. At least the one I got.

Can both the board sma and u.fl connector used for the antenna?

Both SMA and U.FlL antennas are suitable for this product, but they cannot be used at the same time. By default, this product uses SMA antenna. If you want to use U.L external antenna, you need to change the antenna resistance.
