==Update History==
# Jan 2026 Upgrade: Height increased from 7mm to 8mm for better heat dissipation. Compatibility remains virtually unaffectedunaffected, but accessories have changed – please refer to [https://wiki.geekworm.com/File:P165-A_8mm_version_packing_list.jpg P165-A 8mm version]. Both versions are currently shipping.
# We only keep the M2.5*5+4mm, M2.5*5+5mm, M2.5*13+6mm spacers in the P165-A packing list(in August 2021), due to the Raspberry Pi expansion board usually with 12mm or 20mm height, the three spacers combination are enough in application.
# On November 11th, 2020, based on customer feedback, a slightly thicker version was released, which is 11mm thickness. It supports 3010 cooling fan, will have a better heat dissipation function and compatible with PoE expansion board. This new embedded heatsink is named P165-B, while the old radiator will be renamed P165-A from P165.
