X-Track computer 1.54-inch screen version

Overview

Video link: [Homemade] This may be the most powerful DIY bicycle computer you have ever seen

I didn’t feel satisfied with the 1.3-inch model so I re-painted the 1.54-inch model. It has double panels and single-sided components. The battery uses 653450, 1200mAh.

The shell has not been painted yet.

For a detailed introduction, please see 1.3: X-Track computer 1.3-inch screen version

It is recommended to cut the coaxial line of the antenna short. When the coaxial line was not cut during the simulated casing test, the star could not be found for 20 minutes. However, if it was cut short, the star was found.

The thickness of the proofing board should be 1mm.

The antenna routing was calculated using a calculator: Coplanar Waveguide With Ground Characteristic Impedance Calculator
