Don’t you just hate it when you run out of holes and have to use a bridge wire to some free patch on the proto-board? I thought so.
I was expecting the manufacturer to complain about the somewhat high number of drills per unit area, but nothing of the sort! What was an even bigger surprise was the delivery time. Usually shipments from China take weeks. Most of that delay is caused by customs processing. They check everything. This time it only took a week, which is very nice. I got the boards within 2 weeks from date of order. Much better than the usual 3-4.
Unfortunately they slapped their internal reference number onto the front side again. Oh well…
There’s also a “1464” variant, but I haven’t had it made yet. It’s basically the same as the “674”, but wider. One notable difference is that the power-bus is split in the middle, so you can easily use different voltage levels, or just bridge it if not needed.
