I believe it is based on an STM, but I haven't actually seen one.
Ill still build this DIY one when it turns up but I might have a go at the project. And I noticed while skimming the forum threads of your that you may have got 2Mhz working That seems great
It can do 2MHz and uses DMA, this is as fast as it can go.
Umm this might sound really cheaky... But do you have a finished project I could look at and maybe kinda copy, to build?
Not much to it. One blue pill, one display, some wires, a couple of resistors as a voltage divider on the input and optionally a cheap 'scope probe and a BNC socket. It is currently tidied away as I am in the middle of redecorating the house, however there is a brief "how to build" here -> https://github.com/pingumacpenguin/STM32-O-Scope/wiki
Bear in mind that there is very little input protection to the STM32F103 in the pig-o-scope other than the voltage divider, so it is not a fully featured 'scope, just a quick and slightly crude tool... useful in a pinch, and pretty capable for a couple of dollars/pounds.
