Here's some info about a "Xiaomi" X6 "1080P" ("4K" on Ali page) mini spy camera. Very familiar YsxLite manual/app setup - same as many A9 type cams.
It was bought from Ali Express at https://www.aliexpress.com/item/1005008608595789.html
Like several of my A9s, this comes with the Taixin Semi (HugeIC) TXW817-810 MCU at its heart. The TXW817 line consists of these two variations
Like the WinnerMicro W80x, these are based on the C-SKY architecture. CK803 in the case of the TXW817s
Pics of packaging and device inside and out.
silkscreen marking:
STD-X6-MAIN-V01
20240328
No markings on the battery but it's measuring at 3.86v
These two unlabelled pads are RX/TX so from TX at 921600 baud the boot log can be captured
we can see the real resolution of the camera in the initialisation in log - VGA
The camera ribbon has printed on it DC-H8-7 04-6182V1 (I think) - not sure who this cam is by yet.
Despite being C-SKY related I have not been able to establish any CK-Link type connections to it using the HDA and HCK pads. I do not know if the factory program these with those two or with with some USB type thing using HSDP and HSDM. This particular cam doesn't seem to expose RESET either, so I didn't expect CK-Link method to work.
We see here in a previous post that a programming application is provided by Taixin but it looks intended for use with their TXLink programmer
I was hoping it's just a CK-Link rebrand device. Maybe it is and I haven't got the process right with CK-Link. I ordered one from Taobao so that should arrive in a couple of weeks.
I'll add more to this thread in coming days/weeks.
