Below are complete design files for the board You can see in his very long video that he is actually running the PCB routing software and he points out the purpose of individual PCB traces. For example he said "this caries I2C" and talks about why he used specific GPIO pin on the STM32F. If he had bought the board he would not have the design files and the deep knowledge to explain them. He even explains how you can program the firmware without need of a programmer because he included a boot loader. This seems to be a very nice design although he points to possible improvements. https://github.com/DieBieEngineering/DieBieSlave The firmware is here. It seems to be under active development as the last change was two months ago. https://github.com/DieBieEngineering/DieBieSlave-Firmware It is clear that he did not buy this board, if for no other reason the board has his engineering company's name on it I think if you wanted one of these you might have them made in China by a prototype house for not a lot of money Chris Albertson Redondo Beach, California ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
