Hello, I bought 4 boards from your store and paid for them, but you refunded me. I don't know what happened, and I asked you but you didn't reply. What exactly happened? I have already arrived at the computer case, only the PCB board is missing
PCBs and general enquiries
Shipping times?
Hi there! I ordered a SLO PCB last week (Thursday night, which may have been Friday morning in the UK) but haven't heard anything regarding shipping. Admittedly, it is to the US, so I imagine that complicates matters, but I've even emailed Andrea without reply.
I also noticed that he had posted on Reddit yesterday but somehow his account got banned, which is confusing since I can see deleted posts (I have moderator tools at my disposal) and see absolutely no reason to have banned his account from the whole platform.
So, I'm just wondering if everything is alright over there in London.
Trainwreck 25K Pot
I was wondering if there was a specific part number/manufacturer for the PCB mount 25K pot? I'm having problems finding one that matches the pin layout on the PCB.
Differences in the Dumble board version 1.0 and the current Dumble board version dated 2025
What is the difference between the circuit board version 1.0 from 2020 and the current version of the current version dated 2025? I purchased a board off of eBay and the seller failed to disclose that the board was version 1.0 dated 2020.
Hi Jla,
this is Andrea, owner of AAElectronics. Your board is basically as the current one. There have been some minor improvements over the years, but nothing major. You can follow the documentation on website
Happy building :)
Best
Andrea

Hi Tom!
Thanks for the purchase first of all. And yes, everything alright here, all parcels are being handed out to the courier today :)
Unfortunately I’m not sure what happened with the Reddit post: attaching the link to my webpage might have triggered the banning 🧐
Cheers from London
