# The P165(P165-A) Embedded Armor Aluminum Alloy Heatsink Radiator is 7mm high(New Version_Jan 2026: 8mm Height), which is designed with negative tolerance. And it is equipped with M2.5*5+5 copper spacers; so the total height is 12mm, which can support most of Raspberry Pi 4 expansion boards(not support PoE expansion board); if you use expansion board with other height, you only need to replace the copper spacers with the right height. (If you need a special height copper spacers, please contact us.)
