hi there, i want to modify a working pcb: i replaced the 1st digipot with a true 24bit dac. if you like another type, tell me pls. as the digipot only likes 5v max, the voltage has been reduced to 5v on all opamps for the new function. big opamp has to be chosen to drive the galvo i use eagle, you can download it for free i would like the device have its own ip and work wireless. the current atmel only allows a transmission of ca 1000 lines per second @30 bytes due to latency=unacceptable. fr4 - 2 layer as is. so please write to me: what opamps would you choose (mc33274okj), what dac (if you want to replace 1681), what galvo power opamp (lm1875ok)? you would Need to give me the Impression you know what you are talking about. i already lost three weeks with pretenders. pcb layout attached. can you also write the firmware? make 2 pcba samples? or even do the user interface?

Hi, Thanks for your inquiry. We can do this PCB design. I would recommend you to fabricate the sample PCBs with your local PCB manufacturer to save transportation cost!. Moreover, We are also happy to design, fabricate(using third party) and test the PCB in our facility We have third party to develop the firmware. We will also try to get inputs from our thrid party on firmware development. We can offer the firmware development to our third party vendor based on your opinion/feedback on the same. We can discuss on this further. We are analyzing your current schematic and layout. We will get back to you with analysis and feedback you requested. Thanks Nithianand
