ESP32-S2 is a highly integrated, low-power, 2.4 GHz Wi-Fi Microcontroller SoC supporting Wi-Fi HT40 and 43 GPIOs. Based on Xtensa® single-core 32-bit LX7 processor, it can be clocked at up to 240 MHz.
Q: Is this "chip7"?
This chip is intended to expand the product line and coexist with esp32 not replace it.
What do we gain over ESP32?
Support for larger external flash/ram
More GPIOs (39 gpio + 1 gpi, 22 rtcio)
15 ch Waterproof touch sense? & Proximity sensing
WiFi Indoor Positioning (802.11mc)?
External ram access from instruction cache
What do we lose?
RAM? (320KB vs 520KB, or are we not counting IRAM/cache now?)
ROM (128KB vs 448KB)
UART (2 vs 3)
Sometimes internally designated as ESP32C?
