I have a small (hardware) project that will not fit in a Pro Mini memory (flash). I will be using a breakout board of some kind as for only one device making a PCB is not practical.
My first alternative attempt was a Blue Pill (as I had some). I found it a little finicky to program and the new STM32 core (V1.7.0) needs ST's CubeProgram (Suite?).
As it seems the Blue Pill is moving more to the ST IDE and less to arduino I thought I would look elsewhere.
My needs are modest:
- Run at 3.3v
- 9 I/O pins
- Speed is not an issue, the Pro mini 8Mhz could handle the speed but not enough memory
- Size is not an issue but I prefer to keep the board small
My only other consideration is the DUE or Zero.
- Is the DUE/Zero stable and well supported in the Arduino IDE?
- Any issues that would make one a better choice
- Other recommendations?
I've only looked quickly but the NodeMCU seems to fall short on the I/O.
