Telescope: common questions
What microcontroller does the Telescope use?
The Telescope is built around the ESP32-WROOM-32, from the ESP32 family.
How big is the Telescope PCB?
The Telescope measures 56.3 × 77 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Telescope?
75 components, from 36 distinct parts. The full bill of materials is listed on this page.
Where can I download the Telescope design files?
From the Rio6/Telescope repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Telescope design in my own project?
The repository has no license, so all rights stay with Rio6. Use it as a reference, and ask the author before reusing the design.
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 ESP32 firmware against it before you order a PCB.
