Kiku: common questions
What microcontroller does the Kiku use?
The Kiku is built around the ESP32-S3-WROOM-1, from the ESP32 family.
How big is the Kiku PCB?
The Kiku measures 58.8 × 59.6 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Kiku?
35 components, from 25 distinct parts. The full bill of materials is listed on this page.
Where can I download the Kiku design files?
From the SoanGlengan/kiku repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Kiku design in my own project?
The repository has no license, so all rights stay with SoanGlengan. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Kiku 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.
