Cheapest SWD Programmer, CH552 DAP nRF52 flashing

This videos shows a preview of the CH552 as an SWD DAP Programmer

This opens up the possibility to flash Many Smartwatches with an nRF51 or nRF52 and of course man more Micro-controller.

The most interesting part with this is the price, the CH552 starts at about 20 cents
so it will most likely be not more than 50 cents for all the parts, including the pcb.

This is perfectly usable for the ATCwatch project:

Hi, can we use SWD to program bootloader for NRF9160 ? Could you suggest one

[saikalyanmarthi]

Can we use ST-Link to program nRF52 Controller? If so, can you please share any source on how to. I am aware that Segger DAPs support all the controllers but I have ST Link2 as of now and I want to know if we can.

Can you share the code for which runs on the CH552 to use it as SWD programmer?

Which device shows up in the windows device manager if you plug in the CH552 with the modified SWD firmware?

Is the SWD interface open source (I am asking because I see some ARM Limited code in your GitHub)?

Awesome video, I was wondering if we could create a Spy Bi wire programmer for msp430 with ch55x chips 🤔

locked electronics should be scared of you Aaron :) Did you make the PCB where the CH552 is on ? the red/white thing is just an USB hub eh ?
