Hi everyone, Celebrating the Dragon Boat Festival on 7-9 June is not the only reason we feel energetic and refreshed this week. More importantly, our new chip, ESP32-S2, will soon come out, as we have recently announced. ESP32-S2 is a highly integrated, low-power microcontroller supporting 2.4 GHz Wi-Fi HT40 and having 43 GPIOs. Our new chip is based on an Xtensa single-core 32-bit LX7 processor that can be clocked up to 240MHz.
