==Safety Instructions & Warnings==
① Short-circuiting the positive and negative terminals of the capacitors is strictly prohibited. Damage caused by a short circuit is not covered under warranty.

② Before storing, please press and hold the discharge button to discharge the capacitors.

③ Before disassembling or assembling modules, please turn off the main power switch.

==Overview==
'''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.

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.

==Features==
* ''' Raspberry Pi 5 Dedicated PD Handshake Power Supply''': Natively compatible with the Raspberry Pi 5's non-standard 5V5A PD power supply protocol, avoiding the "insufficient power" pop-up alarm triggered by ordinary power supplies; the included USB-C adapter board can be directly stacked on the bottom of the Raspberry Pi 5 for plug-and-play functionality.

* '''100F High-Capacity Supercapacitor Power-Off Protection''': In long-run mode, it can provide up to 3 minutes and 31 seconds of continuous use under a 5V 0.5A load, allowing ample time for data writing and safe system shutdown; the supercapacitor solution eliminates the safety hazards of lithium batteries, offering long lifespan and maintenance-free operation.

* '''Dual Input Compatibility for Multiple Scenarios''': Supports DC 9-24V wide voltage input / USB-C 12V PD fast charging input (choose one; USB-C requires a ≥30W PD/QC charger); internal dual-path isolation circuitry allows for seamless switching between charging and discharging.

* '''Multi-interface 5V5A output: Standard configuration includes two outputs''': USB-C (with PD handshake) and USB-A, sharing a total 5A power output; additionally, there are reserved unsoldered power supply pads for the top pins. Compatible with Raspberry Pi 3B/4B/5, Orange Pi, and other 5V development boards, and can also power other 5V devices.

* '''Hardware-level power-down detection and intelligent power on/off''': GPIO26 hardware direct connection detects power loss; onboard microcontroller manages the power-on signal, automatically powering on when power is restored from a power-off state; the accompanying official demo script supports automatically clearing the power-on pop-up window to avoid forced shutdown triggered by consecutive power losses, suitable for remote unattended operation scenarios (script needs to be deployed manually).

* '''I2C real-time voltage and current monitoring''': Onboard INA219 chip, reading capacitor voltage and charging/discharging current via the I2C interface for easy estimation of remaining battery life; official support scripts are provided for both Raspberry Pi OS and Ubuntu dual-system compatibility.

* ''' Comprehensive safety design''': Integrated main power switch, fast discharge button, 5-level power indicator light, automatic cut-off when capacitor charging reaches 5.2V to prevent overcharge, making operation and storage safer.

==Technical Specification==
{| class="wikitable"
|-
|'''Power input'''||  
*DC 9-24V wide voltage input, DC 5.5-2.1 interface;
*USB-C PD interface, PD negotiated voltage 12V, please be sure to use PD or QC power supply; input power recommended ≥30W;
<font color=red>(Choose one of the two interfaces)</font>	

'''Power input is split into two paths:'''
* One path steps down to 5.2V to directly power the target board;
* The other path charges the supercapacitor. For safety, charging stops after reaching 5.2V.
These two paths are isolated by a circuit, therefore they will not output simultaneously.

|-
|'''Output'''|| 
* 5V5A output, using high-efficiency boost and buck DC-DC power chips; 
*Dual interfaces:''' USB-C '''and''' USB-A''', both sharing 5V5A; Specifically designed for powering Raspberry Pi 5;
* USB-C features PD handshake negotiation, enabling the 5V5APD handshake protocol for Raspberry Pi 5;
* USB-A; 
* Both interfaces can also be used to connect to other development boards such as Raspberry Pi 4B/3B/Orange Pi;

|-
|'''Energy storage unit'''||  
* 100F supercapacitor (series structure, maximum fully charged voltage 5.4V, safe charging cut-off voltage 5.2V)
|-
| '''Charging time''' || Approximately 15 minutes to fully charge (under 30W PD power supply conditions)
|-
| ''Current and Voltage Detection''' || 
Identifies charging and discharging status; 

voltage and current of the supercapacitor can be read via I2C interface, and the direction of the current indicates whether it is charging or discharging;

I2C interface allows reading capacitor voltage and charging/discharging current.

| '''Power-down detection'''|| 
One power-down detection pin;

a logic level of 3.3V indicates the presence of external power input, and a logic level of 0V indicates that the external power is off. For Raspberry Pi, external power loss can be detected via GPIO26 (40-pin); 

for other development boards, it can be connected to a GPIO pin.

|-
| '''Wake-up function''' || Power-off self-start circuit (Raspberry Pi 5 exclusive).
|-
|'''Physical Switches'''||
Main power switch + quick discharge button;

1. One power switch to shut off output for safe module installation and removal;

2. One discharge button for quick discharge and safe storage; for example, after use, it is recommended to press this button to discharge the supercapacitor for safety.
|-
| '''Status Indicators''' || 1 power indicator + 5 battery indicator lights + 1 discharge indicator light
|-

| '''Product dimensions''' || 85×56mm; Operating

==Matching Case==
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.
