A schematic is included here, along with the KiCAD data files, whcih are in KiCAD 6 format.
The PCB is a trivial 2 layer board.
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.
Attach an ESP01(S) board to the header. The PROGRAM button can be used to bring up the ESP01 in programming mode, with the UART pins provided on another header for connecting a USB UART. Ensure the USB UART is in 3.3V mode!
When time allows I will CAD-up a small printable case for enclosing this board.
