Not sure I agree it looks like a prototyp as such, but it looks like a poorly cost optimized design for sure. There are also a lot of space on the PCB for optional parts, such as eMMC, as well as a lot of measurement points, which you normally don’t see outside of PC motherboards designed for overclocking. I guess the next revision should be able to be a lot more cost optimised and most likely also somewhat reduced in size.
The speaker appears to be made by https://www.challengeelectronics.com/
It’s CT08E, not CTO8E. The 2020F1 model doesn’t appear in their catalogue though.
My bad, it appears there’s support for two types of internal speakers on the chipset PCB.
The part marked CTO8E 2020F1 appears to be a tweeter/buzzer as well. Similar to this if you look at the + marking:
Sorry, but you guys are getting a bit sloppy. You missed the Wi-Fi module mounted on the “antenna board” as you call it.
The SSD is actually quite terrible and anything but super fast, as it’s DRAM less. Sure, the SN550 isn’t bad, but it’s far from super fast by anyone’s standards if you know anything about NVMe drives. 2230 NVMe drives are also very rare and only found in a handful of laptops. The only other company I can think of that makes one is Kioxia.
You also missed at least six power phases mounted on the opposite side of the main PCB and a couple of other components on the SoC side, although the latter is most likely related to the power delivery anyhow.
Interestingly the chipset PCB appears to have space for an eMMC chip and a CMOS battery, parts that weren’t included in the final product, as well as a “tweeter”, i.e. an internal speaker.
