KleverLogger: common questions
What microcontroller does the KleverLogger use?
The KleverLogger is built around the ESP32-C3-WROOM-02, from the ESP32 family.
How big is the KleverLogger PCB?
The KleverLogger measures 50 × 50 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the KleverLogger?
61 components, from 34 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 KleverLogger design files?
From the charclo/KleverLogger 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 KleverLogger design in my own project?
The repository has no license, so all rights stay with charclo. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the KleverLogger 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.
