README
README.mdC6dev
A tiny and low power dev board for the ESP32-C6 with 10 GPIO pins, microSD card slot, 64Mbit (8MB) of Quad SPI Flash, USB C 2.0, a step-down converter for efficiency, 2.4 GHz ceramic chip antenna and very cool silkscreen. All pins are labeled with their number, actual GPIO and even other functions.
I've been wanting to make a devboard for a while now so i decided to make one with a RISC-V, low power MCU while breaking out a bunch of useful stuff while still keeping an acceptable amount of GPIO.
It was quite a lot harder than I expected with all the datasheet searching and looking up everything to make sure it works but atleast the routing was quite fun.

Questions
How big is the Devboard PCB?
It measures 27 × 43.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Devboard use?
53 parts, built around the ESP32-C6, TPS62172DSG, W25Q64JVSSIQ and XXDBBCNANF-40.000000MHZ. 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 Devboard KiCad files?
From the ImShyMike/C6dev repository on GitHub, at the commit this page was made from: the board is PCB/devboard/devboard.kicad_pcb and its schematic PCB/devboard/devboard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Devboard 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).
