Does this require protected button-top batteries?
Is it possible to use the UPS Shild together with the RS485 Module?
What will happen if the power adapter supply is insufficient?
Insufficient adapter power will cause slow charging, inability to charge, or even consume battery power while charging. Please pair the UPS with a power adapter of at least 30W. It is recommended to use the 45W power supply included in the LattePanda package.
Can power generation devices such as solar panels or wind turbines be directly connected to the UPS HAT?
In theory, as long as the input voltage is within the range of 12~24V, the UPS can work, but we do not recommend directly connecting solar panels in this way. An overly unstable power source can cause the battery to frequently switch between charging and discharging, which may severely affect battery life. If you want to connect a solar panel, a power management module with voltage stabilization and energy storage functions, such as SKU:DFR0580, should be connected before input to the UPS.
If both the 5.5x2.1mm DC and USB TypeC power supplies of the UPS HAT are connected, which interface will be used for power supply?
Power will be obtained preferentially from the interface with the higher voltage. The USB Type-C PD automatically negotiates for a 15V power supply, and the voltage of the 5.5x2.1mm DC interface depends on the specifications of the power adapter you are using.
