I have finally found a source for Intel's BE200 wifi soldered "1216" sized modules (not the larger 2230 removable M.2 modules) and I was wondering if it is possible to swap the older AX2xxD2W wifi 6/6e with this new wifi 7 module on a laptop. Supposedly both the BE200D2W and the older AX2xxD2W chips use the standard "M.2 1216 footprint" but with an additional inner-ring of pads. We have schematics of various laptops that use the AX2xxD2W chips on this forum. What we need is a schematic of a laptop that uses the new BE200D2W to check if the pinout is identical or not. Do anyone know a link so such a laptop? I plan to swap out the AX201D2W chip on my thinkpad T14s gen 2.

Some additional info on these soldered "1216" intel wifi modules. There are 2 interface methods PCIe+USB or CNVi. The modules with end with 1 in the model code (such as AX201, AX211, etc) use the CNVi interface which is proprietary and is not interchangeable with different versions of CNVi. Laptops that use the PCIe+USB modules end with 0 in the model code (such as AX200, AX210, BE200) may be interchangeable.

Thanks to Diah, got M557-G0 LCD panel buffer board repaired and running ( link ) Next challenge is no WiFi/Bt despite module on the main board and getting 3.3v supply (3.45v measured)- TV Menu shows Network Access Point option (enet unplugged) but menu can't select that entry
- Service Menu shows many Bt/Wifi info missing
- Vizio app shows no WIFIVendor file
- Tried countless enet unplug (user manual said need to unplug enet to get to wifi menu), factory

I've got two boards with the exact same issue, and it's confusing the hell out of me. In short:
1. Both boards behave *exactly* the same; they will show WiFi networks to connect to, and will boot fully to Internet Recovery, but they each show zero available WiFi networks once booted to Internet Recovery. I also cannot switch WiFi "off", as in, the toggle will not move.
2. Both boards will erase perfectly fine using the "erase mac" function; I can wipe them with disk utility, but if I try to install MacOS from Internet Recovery, it says to connect... -
