New bench scope - Fnirsi 1014D, 7", 1GSa/s

pcprogrammer:
Maybe you have them lying around, but you also need a 74LVC125. This is really needed since the FPGA in the scope uses 2,5V and the STM runs on 3,3V, so the levels need to be matched.

pcprogrammer:
They are probably not intended for actual connectors, but why oh why did they use to small a holes. I want to solder headers into these holes to be able to connect to the FLASH and FPGA more easily and only the JTAG one allowed me to stick a standard 2.54mm double row header into it. For the others I have to grind down the pins a bit. Don't want to drill out the holes to not ruin the through hole plating.

Also lifted the metal cans to be able to reverse the power and analog circuitry. Will post pictures and the schematics when I'm done.

pcprogrammer:
Here are some pictures of the naked board and the front part of the case.

Hi Yusef,

I read the FLASH for the FPGA on my scope and compared it with yours. The files are the same, so no problem there.

Cheers,

Need some info on some SMD components.

There are two sot-23 components in the power supply part to turn the scope on. One has Y1 as marking and I found SS8050 as a possible candidate. The other one has R1 as marking. This one switches the 5V so needs to be a beefy transistor or fet.

I found this site https://www.hotenda.com/marking-code/search/list/R1.html but it lists a lot of components with this marking. Google did also gave PDTB1132T as a possible hit but it does not support more then 500mA, so might be to lightweight for the task.
