Pi-UpTime UPS 2.0 is a new and improved version of the Pi-UpTime UPS. Pi-UpTime UPS 2.0 is designed to work with the Pi-4 or other SBCs, such as Odroid, Ausus, Arduino etc. Power is supplied via the 40-pin header or via the micro-USB out port. Powering the Pi and charging the battery is done on the Pi-UpTime UPS 2.0 via a USB-C or a micro-USB connector. Only one connector can be used at any time for power. The micro-USB connector is provided for backward compatibility. The PiUpTime 2.0 has the same dimensions as a Pi-4 (or Pi2, Pi3, etc.) and can be mounted securely on a Raspberry Pi using 20 mm spacers for a compact, mechanically secure connection.
