Discover the Variometers

The table below compares the features of Varduino variometers. All Varduinos have an e-Paper display, a pressure sensor and an inertial measurement unit. The differences are in the integration of a GPS chip, and SD card and in the battery size.

All varduinos are compatible with the Arduino IDE as they are based on ESP32 and SAMD microcontrollers.
