The BlueFlys are shipped as a completed circuit board with the components listed in the product page. Shipping in this form is much cheaper as it makes the package less than 20mm thick, and I can use the saved time to focus on making more circuit boards. See these blog posts for assembly instructions:
- BlueFlyVario_Bluetooth_v11 Assembly with Sky Blue Case
- BlueFlyVario_TTL_GPS_v11 Assembly with the Kobo Glo
Once you have assembled your vario adjust the hardware settings using the manual below and software for your platform.

The Hardware Settings Manual provides a comprehensive description of the range of hardware settings available on the device.
