I have a decent stock of 60V controller, it consists of XCM-V microcontroller. I have to change the parameter of the chip to tune it down to 48V. I tried eXtended from this thread but since it is XCM It doesn't recognize the controller. (I was using CH340 - TTL) Then I tried using UART in the program downloaded from PheobeLiu Gdrive. But the program is not reading the TTL.
1. Which connector can I use which are universally present, as I have time constraint?
2. I have also checked the this thread I have to searched this port but not available in INdia. Is there any other alternative
(Also it doesn't have any switching port to change the votlage - which is why I am looking to make changes in the chip)![Screenshot_2025-11-26-15-51-02-51_680d03679600f7af0b4c700c6b270fe7[1].jpg](https://endless-sphere.com/sphere/data/attachments/242/242194-a384436902f87138be1834a09e20ae58.jpg "Screenshot_2025-11-26-15-51-02-51_680d03679600f7af0b4c700c6b270fe7[1].jpg")
