My kitchen board is ready for the new challenge… 
Has anybody tried the newer TP-Link ax900 +bt with the Lyra and can confirm it’s working or it is better to stick with the older ac600 +bt?
I’m intending to use with Calculinux. I’ve ordered all the parts and just waiting for delivery.

In order too download without a already working wifi connection
Simple USB DHCP Configuration (Linux Host) - Internet Connection Sharing
No need for iptables and setting sysctl ipv4 ip forwarding
1. Determine the USB Connection name used for the Luckfox Lyra:
It typically wont be Wired connection 1
nmcli connection show
example
NAME UUID TYPE DEVICE
Wired connection 100 c57d31eb-bd98-365d-94df-60c2b875d4cc ethernet –
2. Apply shared internet connection:
sudo nmcli connection down "Wired connection 100"
sudo nmcli connection modify "Wired connection 100" ipv4.method shared
sudo nmcli connection up "Wired connection 100"
3. Obtain a DHCP client IP for Luckfox Lyra
adb shell dhclient usb0
Setting LLMNR support level “yes” for “2”, but the global support level is “no”.
4. View IP Address chosen for Luckfox Lyra
arp
Address HWtype HWaddress Flags Mask Iface

Shout out to benklop in the calculinux discord for helping me build amfora to browse Gemini Protocol, I think it’s a perfect fit for this little machine

Here my ad hoc solution for internal usb connector:
Screws replaced with bit longer, 10 mm round distancer made from transparent rubber pads. The only disadvantage is on/off button which is out of normal reach.
The USB WiFi is inside, note the green light. No modification on back case!

I’m working on devicetree overlays, which will provide a way to make changes like this. I’ll provide an example overlay with 100khz operation..

I haven’t personally tried the AC900 one, but I think it should work. It appears it should use the same aic8800 driver, but there are conflicting reports. I’m unsure if bluetooth will work - I’m going to do some more research on this..

Hi everyone,
First of all, I would like to thank the community for all the work, testing, notes, and shared experiences around running Linux on a modified PicoCalc using a Luckfox Lyra B instead of the original RP2040 board.
Thanks to the information posted here, and after quite a few attempts, I was finally able to complete the project successfully. There were some confusing steps along the way, especially around Maskrom / Loader mode, selecting the correct storage target, and flashing the Ubuntu image, but the previous work shared by other users was essential to understand what was going on and solve the issues.
I wrote a detailed document describing the full process I followed. I hope it can be useful to anyone else trying to do the same modification or experimenting with Linux on the PicoCalc.
Here is the GitHub repository:
Thanks again to everyone who contributed information, tests, images, tools, and explanations. This kind of community work makes projects like this possible.

Astralixi pre-release binary should work on the luckfox lyra
Can’t wait to try that out! Can someone help me with installation? I have the base lyra model without nand flash so I just imaged the sd card using the tf flashing method and it’s booted up fine but the text looks very large and not like everyone’s screenshots. What am I doing wrong?
Hi! With the installation process I followed, based on the forum thread, I got the same result. So I think what you are seeing is normal for that image/setup.
Just to understand better: what were you expecting to see? A smaller font, a different console layout, or something closer to the screenshots shared by other users?
I wrote a small installation guide on GitHub with the steps I followed. I’ll attach the link here in case it helps.
Thank you and yes it was very helpful I did at first try to follow your guide up until the part where you hold boot and plug USB-C into the lyra. Since my Lyra is not the B version it does not have nand flash and I cannot do that step so I just flashed the sd card. I used the Ubuntu version from the GitHub link you provided.
If you look closely my font is wider than yours. I was expecting to see sharper narrower font like in your image. I think mine is defaulting to 320x320 but with yours and other it is using the full picocalc resolution of 480x320. Is there additional set up needed via adb for the Lyra base version? I have not used adb at all yet.. just flashed the sd and booted.
