Microcontroller selection

Post by leversole »

My project requires 2.48k or so of sram, I am looking for a nano sized microcontroller. I tried an ESP3266 and am having compatibility issues with certain libraries. Are there any choices with slighly more SRAM in a small form factor, inexpensive controller that may be more compatible with libraries written for the arduino? The project currently runs n a MEGA but I need seven separate instances and I don't have the room, and what a waste of power, pins, and money! Two of the libraries needed are the SH1106 OLED and a rotary encoder library.

Thanks

Our QT Py Trinket boards are small. If you need more pins look at the ItsyBitsy boards.

These days the cost of a SAMD21 board is about the same as an older ATTiny or 32u4 board, so while these may be overkill in terms of capacity for your needs, the pricing is just fine. So look at the "M0" boards, not just the boards with older chips.

Thanks, I think any one of those will work! I think I will try the trinket M0...I assume it will work with the SH1106 OLED library and some rotary encoder library?
Thanks again for the recommendations!

It should, with the Arduino libraries. Buy one and try it :) .

The Qt Py is a little more modern and has a few more pins.
