WiFi bit is an open-source printed circuit board by SolderedElectronics, from the SolderedElectronics/WiFi-bit-hardware-design repository on GitHub. It is a 2-layer board of 202.8 × 210.4 mm with 1,234 parts on 46 nets, routed with 3,390 tracks and 1,935 vias.
It is built around the U262-161N-4BVC11. Its parts include 150 resistors, 90 switches, 60 capacitors, 30 ICs and 15 diodes. It belongs with the radio and wireless boards and the ESP8266 boards of this library.
Micro:bit is a very interesting board with lots of options that are used by many children in school or hobbyists, but who can say no to new features! So we decided to make a micro:bit add-on that will enable internet connection via WiFi! Finally, you’ll be able to connect your micro:bit projects to the Internet and to connect to the well known Internet of Things. WiFi:bit add-on is easy to use through a MakeBlock add-on or using completed Python examples.
Just insert micro:bit to the add-on, plug in the power cable (required) and you are ready! Open the examples and start sending and receiving data from the internet. There are even two easyC connectors on the WiFi add-on, which allow the simplest connection of I2C sensors and actuators with micro:bit. There are also available pins on the board which are isolated on standard spacing used for breadboard connections or connections with cables to additional components!

mfolejewski/PicoBerry
PicoBerry - small CM4 carrier board with full 40-pin GPIO header

It measures 202.8 × 210.4 mm and has 2 copper layers, 1.6 mm thick.
1,234 parts, built around the U262-161N-4BVC11. 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 SolderedElectronics/WiFi-bit-hardware-design repository on GitHub, at the commit this page was made from: the board is CAD/V1.1.1/PANEL/WiFi_bit.kicad_pcb and its schematic CAD/V1.0.0/WiFi_bit.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask SolderedElectronics before reusing the design.
