A very small and basic ESP8266 breakout board
Breakout is an open-source printed circuit board by skorokithakis, from the skorokithakis/tiny-ESP8266-breakout repository on GitHub, published under the BSD-2-Clause licence. It is a 2-layer board of 25.6 × 23 mm with 12 parts on 17 nets, routed with 118 tracks and 2 vias.
It is built around the ESP-12E and SPX3819M5-L-3-3. Its parts include 5 resistors, 2 capacitors, 2 ICs and 2 connectors. It belongs with the interfaces and adapters and microcontroller boards boards and the ESP8266 boards of this library.
This is a tiny ESP8266 breakout board. I made it because the small breakouts I bought took up the entire breadboard and didn't include basic pullup/pulldown resistors.
This repository includes a branch with an even tinier version that is smaller than an ESP8266 12E. It's the size of the 12E minus the antenna, and it includes the voltage regulator and all the capacitors and resistors the ESP8266 needs to boot, but it doesn't include through-hole connectors (so you will have to solder wires directly onto the ESP8266 contacts).
It's for when you really really need as much space as you can. Fabricate it at 0.4mm thickness and enjoy.
If you just want to buy the PCB directly, here's a paneled v1.4 version from Dirty PCBs, which includes 40 breakouts for $14. Note that the boards come without components, and you'll have to solder them yourself. You'll need:
If any of the links above aren't working, just search your favorite site for the components or visit your local electronics shop, they should have all of these.
You can use these ESP8266 versions with this PCB:
Use the board however you want, it's under the BSD license, here's what it looks like:
The files are standard KiCad files, go nuts.

CoreanXka/SlimeVR-Tracker
基于上述原因，诞生了这个项目，解决了上面的问题，并具有以下特点： - 超小尺寸，超高集成度，仅比开发板长1mm。 - 整合接口，仅用一个Type-C接口实现充电与程序下载。 - 集成最最最重要的电池保护芯片。 - 预留电池引脚接口和开关引脚接口，锂电池不再直连3.3V引脚，而是会先经过降压芯片降压后输出。 - 智能切换供电，在有外部USB供电的情况下会切断锂电池供电并进行充电，断开供电后自动使用锂电池供电。 -…

An RP2350 based brushless motor controller
It measures 25.6 × 23 mm and has 2 copper layers, 1.6 mm thick.
12 parts, built around the ESP-12E and SPX3819M5-L-3-3. 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.
From the skorokithakis/tiny-ESP8266-breakout repository on GitHub, at the commit this page was made from: the board is breakout.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Its repository publishes it under the BSD-2-Clause licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
