X-NUCLEO-SNK1M1 (tested on Rev 1) or X-NUCLEO-USBPDM1.

Create a USB-PD Sink Device with the NUCLEO-G071RB board and the X-NUCLEO-SNK1M1 or X-NUCLEO-USBPDM1 shield by using STM32CubeIDE software.

Use the X-NUCLEO-SNK1M1 or X-NUCLEO-USBPDM1 shield that includes a TCPP01-M12 protection circuit and provides a USB Type-C ® connector.

I think it is quite likely that the vendors selling them on taobao are after all the same vendors on aliexpress, ebay. The prices as i see them from my station is in CNY and the webs are in chinese Some of them selling those apparently same boards on taobao as those on aliexpress / ebay apparently offered to solder the sram chip for additional price One of them on taobao like mentioned prior offered an option with the sram soldered

IS61WV51216BLL as it turns out is quite easy to find on ebay, aliexpress and they are available from the ‘traditional’ sources e.g. I actually resorted to getting one without the sram soldered but with the empty pin pads partly due to cost and partly due to the merits of other components bundled on the board. Only provides an empty pin pads for a IS61WV51216BLL

Those who wants to play with external sram on stm32f* series boards need to go for those with stm32f(xxx, e.g.103}t6 boards found on ebay,aliexpress I look at the number of pins of my blue pill and the size of it could afford a shield, so I create this post. But I won’t do that I bought a Due(92k) cause the shield makes it bigger, but they are 5cmX10cm which is not my target. I see the light of hope.īecause when I still using Arduino boards I read about an article about adding external SRAM with a shield to Arduino mega(8k -> 56k). Now with BP in my hand and run my sketch successfully. That’s why I found the mysterious island of stm32duino I already ordered a 64k stm32F103 and a 192k stm32F407, not arrived yet. And I don’t think the instance could be shared, I’ve already made up my mind, won’t change my code’s strategy.

So it’s about 2k/20*1000 100k byte SRAM I need. My target is to create about 1000 instances of function class with a 5cmx5cm board.

I tried this on Arduino boards like uno, pro mini, the number of the class instances is limited by the SRAM (about 20), which could only do very simple tasks such as Arduino examples. I think they should be in the SRAM, and fast speed is necessary. The instance is initialized when the board start and kept in SRAM for the whole lifetime cause they are not used only once, they are like global variables. So I simply create some instance of function class to make up the logic.

I don’t compile the visual logic into scripts then upload, because I don’t know how to do that, it’s not Arduino IDE could do I guess. I’m trying to make a visual editor for Arduino boards myself(very simple and basic). I’m wondering if there is an SRAM shield or module for Bluepill or some other STM32 board not so big? Cause STM32 got a few more pins than Arduino, I guess maybe it is possible for an STM32 board 1/3 ~ 1/2 size of an Arduino Mega/Due to got an external SRAM?Īnd there are small boards with an external SRAM chip onboard already.Ĭould search: “STM32FXXXZXXX” + “SRAM” something like that.Īnd this post is about how to use the external SRAM: There is not a very cheap SRAM shield for sale, so I just bought a Due instead, and that also gets me a faster processor.īut the Mega size is not good for my project, I wish to use multiple small boards, not a single big one.

I read about a post of adding external SRAM to Arduino Mega before, I remembered that expand about 50k memory to the mega. The reason is that I’m lack of SRAM and need a faster processor. I used to use Arduino and came to the STM32 world lately.
