    I am unable to compile the sketch given in GPS_IMU_SD_Logger.ino. There seems to be an issue with the line HardwareSerial Serial1(2); as it causes the following error:

    Arduino: 1.8.8 (Mac OS X), Board: "ESP32 Dev Module, Disabled, Default, 240MHz (WiFi/BT), QIO, 80MHz, 4MB (32Mb), 921600, None"
