This UPS power supply module is designed for the Raspberry Pi 5. It negotiates 5V5A PD output with the Raspberry Pi 5 through a USB-C port, allowing the Raspberry Pi system to automatically recognize the 5V5A Charging input uses a USB-C interface, supporting only 5V PD. The USB-C output interface supports PD negotiation with the Raspberry Pi 5 The module is equipped with two 21700 lithium batteries, with a combined capacity of up to 9600mAh The module includes current and voltage monitoring functions for both battery charging and discharging, as well as 5V discharge current and voltage monitoring (can bad via I2C pogo pins) The circuit board uses a four-layer design, enhancing the current and heat dissipation efficiency Dimensions: 84 x 56mm. Optional 5V 2.54mm-2pin Output (fan connector) The product appearance and printed words may vary depending on the batch, but this does not affect use Color: As Shown Material: PCB Specification: USB Package Contents: 1 x UPS Power Module Only the above package content, other products are not included.
