Hello community, this is my first post here (and I guess this is related to the very good documentation for all question around this complex system). I already assembled my own SEQ V2 based on that old PIV 18F452. Now I want an upgrade, and of course I very attracted by that nes V4 with STM32! Since I do not have too much time in making soldering tests I thought about the following alternative: at ebay a company from Thailand is selling complete evalutaion boards with an included: - socket for LCD - SD-card slot - USB interface - RS232 interface for boot-loading - some other options which might be helpful. The price is roughly 30€ + 6€ shipping and ?€ duty - quite interesting! Just search for "STM32". The drawbacks are: I of course have to adapt my I/O configuration to the given connectors, possibly some pins have to be redefined in the software! And this variant has only 128kByte of Flash and 20kByte of RAM. Here are my questions: - are the available Flash and RAM sufficient for the SEQ V4 implementation? - have some of you made own test with this or other evaluation kits (like the primer 2)? Thank you solarvent
