FOSS-ASIC-TOOLS is all in one container for SKY130 based design both Analog and Digital. Below is a list of the current tools already installed and ready to use.

Fade is an ESP32-based animation system. It can drive WS2812/Neopixel addressable LEDs, PWM-based devices (LEDs or anything else that supports PWM), and hobby servo motors.
Sequence Controller is an open-source printed circuit board by ericgu, from the ericgu/Fade repository on GitHub. It is a 2-layer board of 30.5 × 57 mm with 12 parts on 37 nets, routed with 126 tracks and 26 vias.
It is built around the BSR202N-VB. Its parts include 8 transistors, 1 IC and 1 connector. It belongs with the ESP32 boards of this library.

The installation files can be found here.
Run WinFadeInstaller.msi
These tools will be used to copy the Fade system onto the ESP32
How to Install Esptool on Windows 10
It's good to have experience copying programs to the ESP32 from the Arduino IDE or another IDE before you try this.

Finished support for remoting. This allows one ESP to drive multiple ESPs. There is a new LED type ("UdpSender") that will take commands for a specific of channels (LEDs or servos) and send them out over the local network using UDP. The remote ESPs use the "UdpReceiver" type to take those commands and send them to the local hardware.
This is for two primary scenarios: if you wanted to use more than 16 servos in a project, you can set up a remote ESP (or ESPs) and get a multiple of 16 servos. Also, it supports animations across multiple physical instances using a single set of driving code.
In addition, if you want to run code on a computer or laptop and use that to drive the remotes, that is also possible. I've implemented that as a feature in WinFade; you can write your code there and see how it will run on the live remote hardware without having to download the code there. Not sure how much utility there is in that, but it allowed me to easily test the UdpReceiver code that runs on the ESP.

It measures 30.5 × 57 mm and has 2 copper layers, 1.6 mm thick.
12 parts, built around the BSR202N-VB. 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 ericgu/Fade repository on GitHub, at the commit this page was made from: the board is Sequence Controller/Sequence Controller.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask ericgu before reusing the design.
