You can see the blacktop material in the dimple and notch. Makes you wonder what chip is really in there. -
i did buy second kit to check the micro. now in black color. this gen is OK. then i checked the micro in both boards and it is not working in both.
had ordered still one micro on ali.
Function Generator Functionate perfecto. some mods i try but PCB has to work good without the mods.
also caution do not encrease power level above +12V because the micro is not original, not firm.

I've assembled three of the DSO 150's now. Quite Good for what they are. You can get them pre assemble for $25.00 off BangGood.
Don't assemble the Rotor Encoding Switch PCB up side down. LOL, Did that on the first one and took me a few days to figure out what was wrong.Leave a comment:

they write the board does supply from 9V, but you can supply from 12V. NE555 is max 15-16V according datasheet.Leave a comment:

Ordered two of these from BangGood. Not attempted to assemble second unit but the NE555 was dead in the first unit. Replace the 1k/15k Resistors with a Pot and they become variable frequency signal sources.Leave a comment:
