About the Telescope PCB

Telescope is an open source Raspberry Pi PCB design by kaileh57, published on GitHub under the CC-BY-NC-4.0 license. It is a 2-layer board measuring 80 × 100 mm, with 29 components from 17 distinct parts.

Its main chip is the Raspberry Pi Zero, from the Raspberry Pi family. Other key parts include the AMS1117-3.3. By type, the board carries 11 capacitors, 3 resistors, 2 fuses, 1 IC, 1 transistor and 1 connector.

It belongs with the science & space designs in this gallery.

From the project

a telescope by Kaileh

This is a pretty simple Newtonian Reflector style telescope, with a 114mm primary mirror, and a 25mm secondary mirror. I'm making it because I really love taking pictures of the stars, and was able to do some cool stuff a few weeks ago with a telescope at a family member's house! Hopefully this is a (comparatively) low cost way of getting into the field. There's a couple of great dark sky spots near me (Seattle), and hopefully I can update with some awesome pictures.

Telescope: common questions

What microcontroller does the Telescope use?

The Telescope is built around the Raspberry Pi Zero, from the Raspberry Pi family.

How big is the Telescope PCB?

The Telescope measures 80 × 100 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Telescope?

29 components, from 17 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Telescope design files?

From the kaileh57/telescope repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the Telescope design in my own project?

It is published under CC-BY-NC-4.0, which limits how it may be reused; read the license before building on it.

Can I test firmware for the Telescope without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug Raspberry Pi firmware against it before you order a PCB.
