ESP32 Forum

Good evening folks!
Currently i am working on a DIY-project. The goal is a clock, which can be controlled via wifi. For example setting a timer.
But the thing is, that somehow every MCU that i have tested so far, seem not to fit into my project.
Important conditions the MCU needs to be fullfill, is the availability of micropython, a clock that also returns microseconds and enough RAM.

The MCUs i have bought sof far, are:

- ESP32-WROOM (Not enough RAM due to partitions & slightly to big dimensions)
- Raspi Pico W (Clock does not include microseconds which i desperatly need and sometimes not enough RAM)
- ESP32 ProS3 (Has enough RAM but unfortunately to slow)

So do you have some advises or ideas?
I am very desperate at the moment, because all the MCU purchases have seemed pointless.

Warm greetings

Difficult to advise. How much RAM is enough? How fast is fast enough? If speed is critical, why are you requiring micropython? A compiled Language such as C or C++ is likely faster in many applications. Did you check the specifications in the various ESP32 mcus to find the fastest and most RAM support? Some MCUs are dual core so that can help with speed in some applications.
