TrackPad thx Mald0n ofc works - solution for me here - 

 

 

now just wifi (still waiting delivery my ebay order  )

Not sure atm, but seems i have big battery drain on this hack... how i check this?

This model has tewo graphics card, but in System info only integrated intel, no GTX here (its ok ofc), I just thought it might be the second graphics card. Neither cooling (ventilatory) somehow do not contact, so probably there will not be a problem ...

Atm wifi/BT with DW1820a (masked pin) but only 2,4GHz and BT. Waiting for new CN card. (tested on Mojave 10.14.6. connected on USB 3.0, but i think its also work on Catalina)

Still battery draining i think, its like 1% per 1-2 minute

 

Also waiting for Lenovo ideapad 340C-15 L340C-15 L340-15 HDD HARD DRIVE CONNECTOR CABLE & Caddy, bcoz have only 512SSD inside and cant connect SATA disk without this

Dual boot working on one drive ofc, but if Windows or OSX collaps, mostly both system collaps, so i want two physical disks

If you have Elan touchpad, you can share your „patched” folder?

Finally another DW1820A arrive (CN-096JNT), but same trouble like the first one.. works only 2,4GHz and BT and with "tapped" pins

i dont recommended using this card with this model laptop.

Also finally arrive HDD cable https://www.aliexpress.com/item/4000538612652.html?spm=a2g0s.9042311.0.0.23a74c4djD2wg3 (inside laptop only connector for SATA and m.2 connector), 512 m.2 inside and now second disk on SATA3

Now i waiting for new https://www.ebay.com/itm/Broadcom-BCM94360NG-WiFi-Card-better-than-DW1560-BT4-0-Adapter-802-11ac-1200Mbps/283783627652 (a little expansive than DW-1820a) wifi modul and we see.

Finally Broadcom BCM94360NG WiFi BT4.0 Adapter 802.11ac 1200Mbps arrived.

Inside laptop Lenovo L340-15IRH Gaming with Catalina 10.15.4 works without drivers (native). BT works. Airdrop works. Dont have atm Apple watch, no tested..

BUT!

same laptop with dualboot Catalina / Windows 10 Catalina ok, Windows 10 freeze with this card. No idea if i got bad piece. Tested in second laptop (toshiba) and in Windows some freeze also, but less. Clean instalation Win 10 in Lenovo still same, clean install in Toshiba all ok.

i tested some pin masking, also another card with same chip via convertor from miniPCIe to m.2

Actual result.

If u want only using this wifi card on Lenovo L340, u can for Catalina, but no for Windows (maybe need patched for Lenovo, no idea..). L340-15IRH Gaming has GTX1650 graphics, which dont work in macOS, so for this reason - gaming laptop - i use dual boot with Windows 10.

I still using DW1820a with 2,4GHz only and BT (aidrop works) and looking for another solution.
