Introduction: Reviving the DSO138 DIY Digital Oscilloscope Kit

My DSO138 DIY Digital Oscilloscope Kit had a trouble in the firmware update. And it did not work anymore.

Even following these instructions it was not possible to revive the DSO138 DIY Kit ( )

Step 1: Solution

After several attempts to fix the problem, here was the solution: My step is to just download stm32flash ( and using the command:

Stm32flash -w 113-13801-061.hex -v -g 0x0 COM3

COM 3 is my USB TTL converter.

Step 2: Tools

DSO to USB TTL connections:


TX to TX

RX to RX

    Some of the files mentioned must be downloaded . The url's wont load to comments so you need to put them in the instructable . In particular the hex file you uploaded to the oscilliscope
