Overview
ESP01LEDDriver is an open-source printed circuit board by aslak3, from the aslak3/ESP01LEDDriver repository on GitHub, published under the GPL-2.0 licence. It is a 2-layer board of 53.3 × 49.5 mm with 32 parts on 27 nets, routed with 161 tracks and 23 vias.
It is built around the FT231XS-R. Its parts include 8 capacitors, 7 resistors, 5 connectors, 3 diodes and 2 ICs. It belongs with the ESP8266 boards of this library.

A schematic is included here, along with the KiCAD data files, whcih are in KiCAD 6 format.
PCB design
The PCB is a trivial 2 layer board.
Using
After coming across the ESP01 I was very impressed. It seemed like an excellent solution to problems where a very small controller board was needed, such as running WLED to control addressable LED strips. However the LED strip attachment board I could find used an odd arrangement of receiving power by attaching a USB-A plug directly to the board. I wanted to use a power lead of some description, going to the controller board which then had the LED strip screwed into it on terminals. As I was ordering some other boards, I thought I would knock up this board and order it at the same time.
Power can be supplied via 5V on the barell plug, or 5V via a USB-B connector. The FTDI FT231XS is optional: if included on the board then it is possible to program the ESP01 in-place via the USB connection. Otherwise it must either be programmed using a dedicated board, or programmed when attached to this board but via a USB TTL (in 3.3V mode!) UART attached to the four header pins.
In either case, the PROGRAM button can be used to bring up the ESP01 in programming mode.
TODO
When time allows I will CAD-up a small printable case for enclosing this board.

Questions
How big is the ESP01LEDDriver PCB?
It measures 53.3 × 49.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ESP01LEDDriver use?
32 parts, built around the FT231XS-R. 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 ESP01LEDDriver KiCad files?
From the aslak3/ESP01LEDDriver repository on GitHub, at the commit this page was made from: the board is ESP01LEDDriver.kicad_pcb and its schematic ESP01LEDDriver.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ESP01LEDDriver design in my own project?
Its repository publishes it under the GPL-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
