Altimeter super thin: common questions
What microcontroller does the Altimeter super thin use?
The Altimeter super thin is built around the ESP32-S3, from the ESP32 family.
How big is the Altimeter super thin PCB?
The Altimeter super thin measures 54.5 × 18 mm, has 4 copper layers and is 1.6062 mm thick.
How many components are on the Altimeter super thin?
79 components, from 46 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 Altimeter super thin design files?
From the icl-rocketry/Ricardo-Altimeter 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 Altimeter super thin design in my own project?
The repository has no license, so all rights stay with icl-rocketry. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Altimeter super thin 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.
