Hello, I am Alex from Serbia. I am trying to locate the manufacturer of 600W digital step up module (like this one). Closest I could find is on your site here

I have few of them and the STM8 (STM8s103k3t6c, to be exact) MCU unit is not responding from the start. By replacing the control module (and the STM itself at the end), I figured out that it is the problem. I would like to reflash it, even have some spare chips, but cannot find appropriate firmware. I would be very grateful for your help. Thank you very much for your response.

Sincerely,
Alex.

Hello Alex，

Do you want to control converter via serial port communication? We are sorry this converter doesn’t support serial port communication. Any more questions, please let us know.

Best regards.

Thank you very much for your reply. I don’t want to control converter, just to flash chip (my main STM8 chip is dead and the converter is not working). I want to flash microcontroller via SWIM. There are pins on smaller module (the one with display) on the left corner for SWIM programming. It is the same as on mine.

I’d appreciate if you could share firmware for this module. Thank you.

Hello

The pins you means can’t work for any data transmission. It is jsut a blank area.

We are sorry we don’t have firmware data.

Best regards.
