WireGuard for the ESP32
It's interesting how the ESP32 has become the de facto IoT MCU used in almost all new IoT products.Other companies like TI and STMicro had their own cheap WiFi/BLE MCUs but their devkits used to be too expensive for hobbyists and students. But the Chinese startup behind the ESPxx chips made sure that their devkits were cheap enough for hobbyists and students and through that influence they now also dominate the professional industry.
