About the AstrotrackerH1 PCB

AstrotrackerH1 is an open source PCB design by jaydenaleung, published on GitHub. It is a 2-layer board measuring 111.3 × 70.7 mm, with 24 components from 8 distinct parts.

Other key parts include the DEVKIT_V1_ESP32-WROOM-32, TMC2209_SILENTSTEPSTICK, QMC5883L_COMPASS, NEO-8M and i2c_LCD. By type, the board carries 7 ICs, 7 switches, 7 resistors and 3 modules.

It belongs with the robotics & motion designs in this gallery.

From the project

DIY star tracker camera mount for astrophotography. Includes a 3-axis rotational gimbal, automatic North Pole alignment, and possible upcoming GoTo integration.

See JOURNAL.md and the BOM below for an in-depth explanation of these numbers.

There are always three parts to an engineering project like this, at least for the Highway YSWS program. One is computer-aided design (CAD) modeling; for large projects, this often takes the most time, as it did with this project. Another is printed circuit board (PCB) design, which is the electrical component of the project. Finally, the brain of the build is programmed in the software part, where firmware is written onto a microcontroller that controls the hardware. See…
