Very nice Felice! I am finally planning my build after a long wait. Please share what is in each section.
Thanks. nash
Thanks. nash
Hi nash,
This is also my very long project too. It have following msections
1. 3 Power supply for dam19x1 is LT3045, 1 for eRed Dock also LT3045
2. Buffer Designed to use Sparkos Pro or Sonic Image Opamp, also powered by LT3045 too
3. controller section use Pi Zero 2W to drive 5inch LCD, serial line was isolated with dam19x1 by Si8641
…
Thanks
The 5 inch LCD was driven by Pi Zero 2W via HDMI, they create a lot of noise and affect to sound, so I have to isolate them by using Si8641,
Can you please specify what you mean by “newest” Dam 1941 board? Is there a new iteration of boards for DAM1941?
The newest is just bought from soekris, i saw some of change in parts used.
Hello. Please tell me what kind of rs232 cables you use for Soekris connection? I have unitec that worsk good on dams 1021and olso ch340 ttl chip that is usb to rs232 ttl interface. Both of them dont se my dam 1941. I have try putty and theraterm. Bye

hi
I'm looking to find one of the following opamp opa1678, opa1652, opa1612 but they don't exist for now, any equivalent for soekris buffer;
thanks

Does anyone have a 1941 they would consider selling? I have an ongoing project and there is no stock atm.
Please PM if so!
Please PM if so!
Hi all
in the manual it says output resistance 625 ohm but I measure 25 ohm, what's wrong
also soekris says that it can be put into parallel mode, how set this oprtion΄

Hi, a strage issue come after the 1.24 firmware update, my DAM 1941 and 1921 not work, no green LED pop up after,
After some hour of investigation found it work only if the power applied after power (all other hardware) like the Pi, I really not understand why because it work automatic source selection as before and nothing change on the hardware,

Now it's time to release the dam2941, a backwards compatible update to the dam1941. It's in stock, and as I can actually get the used FPGA I expect it to stay in stock....
There isn't the big differences from the dam1941, just the new Lattice FPGA, it should be a direct replacement....
For now I only have the dam2941, later on I will probably also release a dam2921
