Esp32-balloon integration: common questions
What microcontroller does the Esp32-balloon integration use?
The Esp32-balloon integration is built around the ESP32-C3_Mini_V1, from the ESP32 family.
How big is the Esp32-balloon integration PCB?
The Esp32-balloon integration measures 45 × 38 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Esp32-balloon integration?
10 components, from 8 distinct parts. The full bill of materials is listed on this page.
Where can I download the Esp32-balloon integration design files?
From the felixfelix-bot/esp32-balloon-integration repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Esp32-balloon integration design in my own project?
The repository has no license, so all rights stay with felixfelix-bot. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Esp32-balloon integration 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.
