Does the ESP32-C2 have a low-power (LP) core?
No -- the ESP32-C2 has no separate low-power (LP) core; only its main CPU core (up to 120 MHz).
ESP32-C2 vs ESP32-C5: what's different?
The ESP32-C2 is a single-core RISC-V SoC at up to 120 MHz (272 KB SRAM); the ESP32-C5 is a single-core RISC-V SoC at up to 240 MHz (384 KB SRAM). Wi-Fi: Wi-Fi 4 vs Wi-Fi 6. Bluetooth: BLE 5.3 vs BLE 5. 802.15.4: 802.15.4 no vs 802.15.4 yes. Low-power core: LP core no vs LP core yes.
Notes
- No standalone AES/RSA accelerator or DS peripheral (unlike C3/C6)
- No native USB; in-package flash pins are not bonded out as GPIOs.
- Default drive strength is 20 mA for all pins.
