SyncFix64 v1.1

Following the first prototype of the LM1881 based SyncFix64 I made a few minor changes, improving the schematics and layout. Then I was ready to order the first batch of properly manufactured PCBs. The boards took a little over two weeks for production and shipping.

This was also my first try at ordering a v-cut PCB panel and I’m quite satisfied with the result considering the resulting low price per unit. I assembled one of the boards tonight and the device is working properly. So I assume the whole batch should be fine.

The project files for the updated version 1.1 of the SyncFix64 are available on Github and here is the list of required components:

C1,C2,C3 0805 100n
Q1,Q2 SOT-23 BSS138
R1 0805 100r
R2 0805 680k
R3 0805 10k
U1 SOIC-8 LM1881
U2 SOT-223-3 AMS1117-50
C4,C5 1206 22µF

Update: There are German assembly instructions available for download now.
