README
README.mdIFT-C3
Printed Circuit Board with an ESP32-C3. Version 2.1 (2024)
Version released for the new students. Now integrates the support for the OLED screen and the buttons.
BUGS!!! (fixed in the kicad design, not on the produced boards):
Buttons pinout is wrong, you'll have to solder them rotated 25°. For the Boot/Start button, since I thought there was two buttons in one without verifying, you'll have to be creative to fix it (at least the start button, the boot can be selected with Dupont wires by connecting pin 9 to ground).
Holes for the screen are too small, you'll have to replace the connector or be creative (file the pins works).GPIO 0 is used by the keyboard matrix
GPIO 1 is used by the keyboard matrix and optionnaly for battery voltage measurement
GPIO 2 and 3 are optionnaly used for audio
GPIO 4 is optionnaly used for the light sensor or to control the MOSFET
GPIO 5 is used by the SDA line for the OLED screen
GPIO 6 is used by the SCL line for the OLED screen
GPIO 7 is used by the keyboard matrix
GPIO 8 is used by the keyboard matrix
GPIO 9 is plugged to the Boot button which can be used in your design. The reset button cannot.
GPIO 9 also optionnaly used for the RGBW LEDs
GPIO 10 is used by the keyboard matrix
GPIO 20 is used by the keyboard matrix but also as the Rx UART
GPIO 21 is used by Tx UART

Questions
How big is the IFT C3 PCB?
It measures 54 × 85.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the IFT C3 use?
74 parts, built around the ESP32-C3-WROOM-02-H4, AZ1117CR-3.3TRG1, DIO5508XS8 and PTS526SK15SMTR2LFS. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the IFT C3 KiCad files?
From the Acathla-fr/IFT-C3 repository on GitHub, at the commit this page was made from: the board is IFT-C3.kicad_pcb and its schematic IFT-C3.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the IFT C3 design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
