FPCB: common questions
What microcontroller does the FPCB use?
The FPCB is built around the ESP32-S3-MINI-1-N4R2, from the ESP32 family.
How big is the FPCB PCB?
The FPCB measures 50 × 70 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the FPCB?
74 components, from 47 distinct parts. The full bill of materials is listed on this page.
Where can I download the FPCB design files?
From the Kiya86/Terasaki-Main- repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the FPCB design in my own project?
The repository has no license, so all rights stay with Kiya86. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the FPCB 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.
