==Overview==
The X-FAN40 is a PWM fan HAT designed for active cooling of M.2 devices or dual cooling on the Raspberry Pi 5. It integrates seamlessly with the X1001-Max, X1004, and similar NVMe expansion boards while remaining compatible with standard Pi cooling solutions.
The X12-A1 V1.0 is a stackable battery rack designed to expand the backup power of UPS HAT systems. It uses a parallel configuration of four 18650 batteries, providing plug-and-play battery capacity expansion for compatible UPS HAT systems such as the [[X1209]] (top-mounted) and [[X1203]] (bottom-mounted). Each battery has an independent ultra-low resistance resettable fuse to effectively prevent over-discharge risks; the four parallel XH2.54 connectors support convenient connection and multi-stand stacking, allowing for flexible increases in total power capacity as needed.


Its 40mm PWM fan delivers up to 6.01 CFM - over five times the airflow of the official Pi active cooler - providing reliable thermal management for sustained high-load operations. It is the ideal cooling solution for power-intensive devices like AI accelerator cards and high-performance SSDs.
==Features==
==Features==
* '''Dual-Cooling Versatility:''' Dedicated cooling for M.2 devices or supplemental cooling for Raspberry Pi 5.
 
* '''Seamless Compatibility:''' Designed to fit perfectly with X1001-Max/X1004 NVMe expansion boards.
* '''Parallel Capacity Expansion: '''Can accommodate four 18650 batteries connected in parallel, directly increasing power supply capacity.
* '''High-Performance Airflow:''' 40mm PWM fan delivers '''6.01 CFM''' – over 5x the airflow of the official Pi active cooler.
 
* '''Sustained Performance:''' Maintains stable temperatures under continuous high load.
* '''Independent Protection: '''Each battery is equipped with an ultra-low internal resistance resettable fuse to prevent over-discharge.
* '''Built for Demanding Workloads:''' Ideal cooling solution for power-intensive applications, including AI accelerator cards and high-performance SSDs.  
 
* '''Stackable Top-Mount Form:''' Mounts on top of the M.2 HAT or Pi 5, allowing seamless stacking with other HATs.
* '''Plug and Play: '''Provides four XH2.54 connectors, compatible with specified UPS HATs, requiring no modifications.
* '''XH2.54 Power Output''' - Equipped with 5V power output connectors for expanded functionality.
 
* '''Stacking Design: '''Supports multiple stacks (requires the X12-A1 stacking kit), flexibly expanding total power capacity.
 
* '''Compatible Models:''' [[X1209]] UPS HAT (top-mounted Raspberry Pi), [[X1203]] UPS HAT (bottom-mounted Raspberry Pi).
 
*'''Core Application: '''The X12-A1 provides a backup battery expansion solution for the aforementioned UPS HATs.
