Can STM32F411CEU6 be used instead of STM32F411CCU6TR #3

Hello As the STM32F411CCU6TR is backorder everywhere I was trying to find a replacement. None are stock but there are dev board on ebay with a STM32F411CEU6 and I was thinking of ordering one and take it from that board. The only difference that I am seeing is the flash that is double on the STM32F411CEU6. Can it be used? I am not familiar with those STMicro mcu. Thanks, Fred

Hello Recent the chip shortage situation is really annoying, isn't it? Yes, your workaround plan should work well. STM32F411CEU6 can be used instead of STM32F411CCU6. Those two SKU are same except the flash size as you mentioned. I hope your manufacturing will be successful.

Hello! Yes kind of. Situation was not that bad a year ago with Mouser and Digikey even if we started to hear about it. But since 9 months now it hits pretty bad! So perfect I have ordered the little dev board on ebay and will salvage the MCU from it! I have sent the PCB to be made by JLCPCB and kind of nice to have them solder the small 0402 instead of spending time on this! I was lucky as all other parts except the MCU and the USB connectors were available. I will salvage also the USB from the dev board! I got the last port expander they had. Still printing the parts and need to find a place for the laser cut & engraving. Hopefully will complete this in few weeks (time to get also the board). Thanks! Fred

Hi Sunil, Did you program the firmware binary into the device, but it's not recognized as a USB device? I've uploaded the firmware binary here, so please try it.
