first time trying out a uConsole and was playing around with keyboard firmwares but the one I tried has nasty levels of input lag from the trackball

which firmware is the ideal one to use?

When I received my uConsole, the trackball was unusable, so I bought a pack of 5 from the PengFeiTeng Store on Ali. But I liked the uConsole so much that I didn't want to wait a week or two for new trackballs to arrive. The idea came to me when I was looking for a mouse in my box of computer junk. I saw a ball mouse for the COM port. We've all cleaned our ball-bearing mice, right? Our trackballs are designed in much the same way and often come from the factory unclean and perform terribly.

So, the solution:

pure isopropyl alcohol 99.9% – this is important! It's best not to use rubbing alcohol or food-grade alcohol, as they contain water.

You'll need a medium-hard brush with short bristles. I use the brush I use to pre-wash watch parts, but you can use any brush you find, trimming it first and leaving it about 5mm long.

Dip a brush in isopropyl alcohol and squeeze it against the bottle's neck until it's damp but not dripping. Gently, applying light pressure, rotate the trackball in different directions with the isopropyl alcohol brush for about a minute. Rewet the brush 3-4 times during cleaning. Then, let the alcohol evaporate for 2-3 minutes before turning on the uconsole. The alcohol will dissolve all the grease and dirt inside the trackball, and you'll be surprised how much smoother it feels. You can leave the trackball in the uconsole if it's not very dirty. Or, if it's really unresponsive and you need more isopropyl alcohol, remove it before cleaning to avoid spilling alcohol on the circuit board. I still use the original trackball and haven't replaced it with a new one; I just clean it when it starts slipping.

I'll be glad if it will be useful to someone and get rid of headaches and save nerves. Peace and good to all!

Hi, recently got my aio v2 add-on and started to have fun with it. Had a lot of Cursor agent tuning to get meshcore-uconsole client to work with local network. Suddenly it just stopped to receive packets, sent packets are also never delivered. No errors, device responding, just no life in air. Checked with meshtasticd and tui-meshcore client - same silence everywhere. What could it be?

tl;dr - i only have a CM5 and before i start flashing things i want to know i can recover; but i can't find the EMMC_DISABLE jumper that (should?) be exposed to force boot from SD.

I just got a uConsole (cpi3.14 v5, latest). I had a cm5 (8gb ram, 32gb eMMC) laying around, and with the crazyness in prices want to to use that. A lite (no eMMC) would admittedly be easier with only a small performance hit.

Anyway - how do i set EMMC_DISABLE (pull down GPIO20)?

AFAIK this is the (only) way back from an os image in the eMMC that will start early boot but not get you to a console.

Hello, I Just snatches a cm5 16gb ram non lite (16gb onboard too) on vinted.

I know (sort of) the limits of having 16gb of soldered memory. I won't have access to the SD slot, fine, I will get a non lite later but the price was very good.

Can you please help me on how to proceed?

I want to know beforehand how to proceed, because in 10 days I will get the CM5 and the batteries.

- Nvme: wanted, low priority, 16gb is enough for now, but I want to buy it. What do I have to buy?

- other boards/adapters because of cm5?

- how I flash the OS and boot from it?

I am an IT developer and I was a sysadmin for some years, I am skilled in Linux and I had already worked with tons of rpi but it's my first time with a compute module and it's my first time with onboard memory.

Please help an advanced newbie 😅

Unsoldering some easy part is feasible for getting the SD functionality back? I have a good soldering iron, and a hot air soldering station too. I know how to solder, but I would avoid it if it's easy to mess it up.

If it's too difficult I will just buy a cm5 lite in the future and sell my 16gb onboard one.

Thanks guys!

I just got my uconsole with cm5 lite and installed Ubuntu but some program just doesn’t load , such as Terminal or Firefox. So I just want to ask for guidance on which os are available/recommend for my setup.

I upgraded from 18650s to LiPo batteries. 10000 mAh on both uConsole; one is running a CM5 with the aio v2 NVMe and active cooler, getting less than an hour with lipo; the other is running a CM4 aio v1 NVMe and passive cooling, barely getting two hours with liPo before upgrading. I was getting over 4 hours on the CM4 running sdrtrunk and 2 hours on the CM5. With the results I got with the lipo batteries, I have reverted to using my 18650s. What is everyone else running, and what's your battery life like? I also realized that the LiPo batteries are 3.7 volts
