Teardowns of mods? Specifically the HohmWrecker?

[dustinzinnj]

Does anyone have or do teardowns of mods? pBusardo used to it seems, but I'm dying to know what brand chip is in the hOhmWrecker. I find it hard to believe they "made" the chip by hand. It's probably a re-branded STM32 or some PIC microcontroller. I'm dying to know but I can't bring myself to buy a mod that has no firmware upgrade-ability (my guess is because they are trying to hide the secret that it's off the shelf parts, so no native USB.). I mean it's just so close to being the perfect mod (minus the fugly mandatory styling and no USB). I don't mind not charging my 18650's by USB (although I hate that we haven't evolved there yet.)

Fwiw, this is a prick thing to do. It's also how to lose any electronics engineer as a customer (not that I am). It's probably off the shelf stuff.

Honestly, it's funny that's the only picture they have. I see just fets, nothing of importance on that side. Honestly, it's gotta be some typical micro... even my Tesla 60w TC has a STM32 on it.
