Pros
- Native USB OTG plus a separate UART port
- Vector instructions for on-device ML and audio
- PSRAM for displays, cameras and big buffers
Cons
- No classic Bluetooth (BLE only)
- Octal-PSRAM modules lock out several GPIOs
- Draws more power than the C-series chips
Best use cases
- 01Displays and LVGL user interfaces
- 02Camera and voice-recognition projects
