Pads for UART

[Yoda-BZH]

Have you identified the UART pads ?

Can you provide a schema with the identified pads to connect the UART to ?

Thank you

Hi! The UART pads should be here https://drmnsamoliu.github.io/assets/img/UART.JPG

This is for the C200, is it supposed to be valid for the C210 too ?

[xfarrow]

@Yoda-BZH yes, at least in my C210 the pads are exactly in this position. If you can post a picture of your motherboard we could give a look together :)

I think I identified it, noted 1 to 4. But they're not clearly identified.

Oh, seems like the motherboard schematics is different from mine as well. I am not an expert, but I also think those you outlined are UART pads. However, the lack of clear identification labels makes the process harder than expected because positioning cables incorrectly could damage the camera. I am not able to provide any further information at this moment, but I will try to investigate the matter.

I have the same board as @Yoda-BZH, it seems. It's marked as C210(EU) Ver. 2.20 (as seen also on the photo above). It's using the SSC333 chipset, instead of the SSC335 that I think your version has, @xfarrow.

I've found this https://www.youtube.com/watch?v=egNNp8ImRY0 video where someone went through the trouble of debugging these pins and documenting it (thank you!). So, using the numbers from the photo above, looks like the designation is:

• 1: Tx
• 2: Ground
• 3: VCC
• 4: Rx

3 and 4 are my guess, because it's not clearly shown on the video. It looks like they are trying pin 4 first for the receive pin and it works for them.

Additional thing worth noting from the video is that the root password for that particular board was slplzgjipc. Not sure if it's shared across the version of the camera, version of the board or if it's specific to that particular instance, but making a note here for easy future reference. Worst case scenario, looks like it follows an easy to crack format - the video includes a quick note about that too.

Also, slightly related issue in OpenIPC: OpenIPC/builder#2. It's for the C110 camera, but it uses SSC333 as well, so making a note of it here in case some issues (like the WIFI chip) are similar.

@klimeryk Thank you for your precious contribution!

I have also received ssc333 with same marking which @Yoda-BZH had;
Also, I was able to get UART connection with bridge in picure(red box).
