==Overview==
==Overview==
X1200 is an innovative uninterruptible power supply (UPS) expansion board designed specifically for the Raspberry Pi 5. With its advanced features and robust power backup capabilities, the X1200 is perfect for even the most demanding Raspberry Pi setups.
'''The UPS_Scap_5V5A''' is a supercapacitor-based UPS power module designed specifically for the Raspberry Pi 5. It supports either''' a 12V PD input''' or '''a wide-range 9–24V input '''(use one or the other), and offers three output options: '''PD USB-C''', '''USB-A''', and '''pins''', with a total output of up to 5V 5A. The USB-C port supports the 5V 5A PD protocol required by the Raspberry Pi 5.


'''Please note:''' If the UPS does not detect the RPi5, it will automatically shut down within 3 seconds. So you need to install the RPi 5 on the UPS and make sure that the RPi5 has good contact with the UPS's pogo pins.
The 100F supercapacitor provides ample power for extended battery life. It features a main power switch and bleed circuitry, and can be mounted on the bottom of the Raspberry Pi for power via header pins or a USB-C to USB-C connector. A power monitoring circuitry allows for reading the supercapacitor's voltage and charging/discharging current via an I2C interface to estimate battery life. A compatible USB-C adapter allows for direct stacking on the bottom of the Raspberry Pi 5.

Installation Video https://youtu.be/sKlRIPLSck0
# Power-on/off logic: Most development boards do not have dedicated power-on/off logic for Raspberry Pi 5. After power-off, the system may enter a locked state upon power restoration.
{{#ev:youtube|https://youtu.be/sKlRIPLSck0}}


==Matching Case==
# Recommended solution: After saving the data, the application continuously monitors the power-down detection pin. If power is restored, the application continues to execute the business process; if power is not restored, it will idle and wait for the system to shut down due to power failure.
X1200-C1 is a metal case '''for Raspberry Pi 5 & X1200''' UPS Shield, it also support installing active cooler and Raspberry Pi 5 PIP PCIe to M2 NVMe Shield like  [[X1001]], [[X1004]], [[X1003]], [[X1000]] and [[M901]] on the top of Raspberry Pi 5.  
* Case dimensions: 90.8 x 69 x 62.8 mm / 3.57 x 2.72 x 2.47 inches
* Note: On 12 March 2025, we updated the X1200-C1 case to '''add a row of cooling holes''' on the TF card slot side to '''increase airflow and take more advantage of the Raspberry Pi 5 active heatsink'''.
*Note: If you only need to use the X1200-C1 with the Raspberry Pi 5 motherboard (without the X1200 UPS board), you can separately add 4 M2.5*6+5 screws (or directly use M2.5*27 copper standoffs) to achieve the ideal installation.
