- snuxoll 5y agoThere’s no “switch” (yet), the C3 is their new MCU with a RISC-V core, but they will be continuing to manufacture their Xtensa-based designs for some time.
- tzs 5y agoThey didn't switch to RISC-V. The added RISC-V. Their recent releases have been a mix: September 2019: ESP32-S2. Single core Xtensa LX7. November 2020: ESP32-C3. Single core RISC-V. December 2020: ESP32-S3. Dual core Xtensa LX7. April 2021: ESP32-C6: Single core RISC-V.
- MrBuddyCasino 5y agoDidn't know the differences between the original ESP32 and the ESP32-S3, so I looked it up. The ESP32-S3 is basically an updated version. Major differences: Xtensa® dual-core 32-bit LX6 vs LX7 (better FPU I think?) BR/EDR + Bluetooth LE v4.2 vs Bluetooth LE v5.0 SRAM 520 vs 512 ROM 448 vs 384 USB OTG none vs 1 Plus some minor differences in the peripherals.
