A minimal table to compare the Espressif's MCU families.
| ESP8266 | ESP32 | ESP32-S2 | ESP32-S3 | ESP32-C3 | ESP32-C6 | |
|---|---|---|---|---|---|---|
| Announcement Date | 2014, August | 2016, September | 2019, September | 2020, December |
| Begin by enclosing all thoughts within <thinking> tags, exploring multiple angles and approaches. | |
| Break down the solution into clear steps within <step> tags. Start with a 20-step budget, requesting more for complex problems if needed. | |
| Use <count> tags after each step to show the remaining budget. Stop when reaching 0. | |
| Continuously adjust your reasoning based on intermediate results and reflections, adapting your strategy as you progress. | |
| Regularly evaluate progress using <reflection> tags. Be critical and honest about your reasoning process. | |
| Assign a quality score between 0.0 and 1.0 using <reward> tags after each reflection. Use this to guide your approach: | |
| 0.8+: Continue current approach | |
| 0.5-0.7: Consider minor adjustments | |
| Below 0.5: Seriously consider backtracking and trying a different approach |
