Shuriken Posted February 7, 2016 Report Posted February 7, 2016 28 minutes ago, Phatline said: i have tested the STM32F411xC/E with 512KBytes... and its not working... no flashing LED when pressing Black button, no connection to MIOS Studio ( I did not want to test it... i simply buyd the false Types ...fucking 3 pieces...) The F411 is not really in the same ball park. It's the top of the entry line with less RAM and slower clock. The higher number may have fooled you but F407 is really something else. Too bad you bought 3 pieces. Hopefully you can get rid off them through evilbay. But you are not the only one. In the past i bought an STM32F103RE with a different crystal speed. So even though being the same MCU it still did not work Quote

I got a good deal: two pieces for €41 including shipping. they give some kwantumkorting aka mengenrabatt aka volume discount for 2 pieces, at least on their .nl and .de https://www.conrad.nl/nl/stmicroelectronics-stm32f4discovery-developmentboard-443910.html Fair enough i think, farnell has €8 shipping below €50,- and in austria farnell only deliver to "Companys"... i will order @ conrad austria. thx Quote
Shuriken Posted February 20, 2016 Report Posted February 20, 2016 Just to summarize: Old board Part number: STM32F4DISCOVERY New board Part number: STM32F407G-DISC Quote
Alasdair Moon Posted January 22, 2018 Report Posted January 22, 2018 STM32F407G Mouser => availability .. ZERO, since some months Didigey => availability .. ZERO .. since some months Conrad .. ZERO WattenRott .. ZERO I hope we still find some or the next generation of the boards soon .. Quote

Hawkeye Posted January 22, 2018 Report Posted January 22, 2018 Andy aka latigid on has developed a new core based on the waveshare Core407V, afaik TK. has already successfully used it in his first prototype MBSEQv4+. The new core PCBs should be publicly available somewhen in in springtime 2018! Many greets, Peter Quote
Alasdair Moon Posted January 22, 2018 Report Posted January 22, 2018 @Hawkeye .. now this is good news :D Quote
FantomXR Posted January 23, 2018 Report Posted January 23, 2018 @Alasdair Moon: Sorry! You are right... damn it! But yeah, looks like latigid on seems to have a solution for that. 1 Quote
Alasdair Moon Posted January 23, 2018 Report Posted January 23, 2018 Perfect ... new Controllerboard for the Sequencer .. and I take the old one for other projects ;) Quote
FantomXR Posted January 28, 2018 Report Posted January 28, 2018 I just created a design for a core by myself and ordered it. It's downstripped (has just J8/9 + MicroSD-card reader on board) because I want to test the basic functionality of the circuit first. I'll keep you posted if it runs fine :-) If the design works, it can be easily extended to other people needs. Quote
FantomXR Posted February 7, 2018 Report Posted February 7, 2018 @Alasdair Moon The discovery board is now available again on mouser. 1 Quote
