Still, now it's very hard to order any integrated circuits.
I really don't know who will manufacture the next batch.
After I will manufacture the 2nd and 3rd order batches I have to close or freeze this project due to a very hard situation on the market with components - IC shortage. Most of the ICs have lead time ~52 weeks.
Here are the examples:

Dear Hackaday community!
Really sorry for my delayed response and my project update and status. I have to say 'so sorry'.
Project delayed about one month (I planned to start shipping in the second half of May), but the current plan for shipping is the first half of June.
I need about 2 weeks to assembly the rest of the components. I have all the needed components.
I will assembly manually only 10 pcs (due to is too much work for one guy), the rest of the PCBs I will order manual assembly at some small EMS company service.
During this manufacturing stage I faced on few hard issues:
1. the biggest issue - component issue, almost all integrated circuits are not available on market (empty stock), due to Covid, pandemic and automotive industry mass production.
I sourced components from many different shops, such as Mouser, DigiKey, TME, LCSC, Texas Instruments, Allegro, Kamami, and even Aliexpress and TaoBao.
2. I had 1 week of delay with my PCB manufacturer (DFM review for my approval).
3. I had 1 week of delay due to FedEx service and customs procedure and shipping delivery.
4. In total I have about 3 weeks of delay on the manufacturing stage due to external issues.
5. Now I need about 2 weeks for manual assembly and about 1 week for the shipping process.
Things to do:
1. manual assembly 50 pcs (by me and some EMS company)
2. create simple firmware for push-button controller (microcontroller)
3. test all the boards and functionalities
4. prepare the shipping for all users and customers
5. update and prepare Github documents and user manual
2 weeks ago I decided to left the company, where I worked as a regular employee, to have more time for the MirkoPC project and future designs and soon I hope to create my own company. Next week I will be free for 100%.
The good news is that MirkoPC GEN2 (R1.1) will have a colored pin header (HAT connector) and unique power switch (tactile switch).
Please forgive me for that situation, but I'm just want to finish this project and to deliver ASAP even if this is impossible these days (IC shortage times and pandemic).
So, summarizing I need about 2 weeks to assembly and 1 week for shipping (I hope).
I will send over 40 packages to all my users and customers so please be patient and keep your fingers crossed! Wish me luck!
I attached the partially assembled boards (5 pcs).

Here you can download the 3D STEP file for #MirkoPC R1.1:
In a few days will be available also the STL model of dedicated enclosure for 3D printer (my colleague supports me in this topic)

Components, lot of components...
Due to IC shortage times I sourced components from: Mouser, DigiKey, TME, LCSC, Aliexpress, Texas Instruments, TaoBao, Kamami, Allegro.
Nothing will stop me to finish this project... :-)

just a quick preview - this is what the 2nd and 3rd batch looks like.
I can see two issues for now:
- slide switches on 3rd batch are damaged, too high temperature on the reflow process
- some mezzanine connectors need to correct its placement

For the 3rd batch, I changed the FFC connectors to similar models as on the original CM4-IO board.
This is still a prototype, but in the meantime, I changed a lot of things and I fixed a few issues.
I hope that this time this will be a stable version, ready for mass production.

Today I just received 2 boxes from Fedex.
2nd and 3rd batches #MirkoPC
I'm happy and a little stressed if everything will be OK.
Keep your fingers crossed, lot of work to do.
There is no space for mistakes, everything has to work 100>#/span###

Dear #MirkoPC community!
2nd and 3rd batches are on the way.
I need about 1 week to process the customs procedure and then up to 2 weeks to assembly the rest of the components (missing ICs and connectors).
Lot of work to do yet!
I'm very excited and I hope that the boards will be working 100%.
There is not space for my mistakes.

2021-05-07: current status -> 2nd batch is under PCB manufacturing, please see the log from factory:
next step is the automated assembly process, shipping, customs, etc. manual soldering, testing, packaging and shipping - lot of work to do.
