Hi.

Next one from PPA. Two more PCBs, please.

Greetings Marcin.

If parcels to Poland are missing sometimes, why not to send one with bulk of 20-30 pieces by Fedex, or with other good reputation company, with good insurance paid? It would be finally cheaper&faster for us.
Please, consider this.

Guys, if you dont like how i do this please feel free not to order.

Your product, your rules. I can only adjust to it.
So I hold my order (1 pcb).

Of course, we accept your terms, so please add us to the list.

Thanks!

Two PCB please. Bulk order from ppa.pl.

Please point out mistakes or missing orders.

You missed me. I would love to get 3 unpopulated boards, Thank you much

Just for curiosity what was the total time from first thought to working prototype in hours. Looks like your pumping these out faster than I can read about them

These are partially assembled from China. They are not completely populated.

In terms of my output ...probably the time breakdown.

1. Initial schematic design - 10-30 hrs
2. Routing - 50-100 hrs
3. 1st Build soldering time - 2-3hrs
4. Firmware development - 50-500hrs (tf536 was lower because it was a merge of tf330 + tf534)

I can control everything in my lab remotely so i can sit and do dev watching TV.

Batch is closed and ordered. I've cut it short at 87 because JLC often email me and say that 1 or 2 didnt pass QC from the factory.

Quick question's, if they partially assembled, how does that effect the BOM listed in the batch 1 thread. Is the Xilinx chip pre-soldered. Also how does buffered and unbuffered ram affect the operation in terms of games and such? I envy you, I should have learned to code back in the 8bit days, the CPLD stuff has left me behind

Your time is appreciated and hope you can get back adequate compensation for your efforts
