I’ve had a few requests from folks who want to build their own STM32-DVM-MTR2K boards. While it’s not for the faint of heart, I have decided to make the necessary files available. This article is just as much a story Read more…


It took longer than I’d hoped, but I have just released a firmware update for the I/O processor on the STM32-DVM-MTR2K V2.0 boards. Those who watched it closely had asked the question why did I only connect 4 of the Read more…


This project has gotten a lot bigger than I ever thought it would. What started almost as a dare has turned into something very real. There has been a steadily increasing demand for the STM32-DVM-MTR2K, and while I said I Read more…


Folks, Tonight we completed the addition of NoCo 3171 to the list of dynamically linkable TGIDs on TS1. 0x49 DE N0MJS
