STM32G030F6P6 TSSOP20 crystal oscillator?

[MarkJordan]

As I understand, the TSSOP20 version needs an external oscillator instead of a 8MHz crystal connected directly to the MCU pins. Is that correct?

I'm asking because I have seen a board on AliExpress using this same processor with a 8MHz crystal.

Correct, the TSSOP20 doesn't have an OSC_OUT which means it can't be hooked up to a crystal directly.

No clue what's going on with that board. Schematic doesn't seem available. Probably the crystal is not very useful on it.

Very curious. a schematic (could be typical AE misinfo) is available but shows no crystal

There's also a Baidu (Chinese Cloud drive) download link at the top of that page for a zip file of assets for that board, but it seems to be china only.

On at least one unrelated project, someone thought it was a good idea to connect a 16Mhz crystal to OSC32, I wonder if that's a clever hack or a *** mistake: hack.https://github.com/brunohoplite/stm32g030f6p6_evaluation_board/blob/master/PCB/Schematic_stm32g0f0_eval.pdf

Update: really?!? the word *** is censored? that's so ***ing ***. What a bunch of ***.
