The pressure sensor for the TLPHnodeV2 is also light sensitive. So while I'm not ready to commit to a full enclosure I do need something to test with. I'm having a mount 3d printed. The 3d model of the PCB was exported from KiCAD and then imported to FreeCAD so that I could visually check for interference problems.

The pressure sensor on the TLPHnodeV2 is light sensitive and needs a cover. I’m not ready to commit to a full enclosure, so I designed a simpler cover for board bring-up and evaluation. The cover was designed using FreeCAD and is being printed at Shapeways.

My notes on uploading a 4-layer KiCAD design to OSH Park using gerber files. The process was much like a 2-layer board, though a 4-layer board was not detected until I switched to Protel file name extensions.

(There was also no problem if I uploaded the .kicad_pcb file.)

I pulled together the pieces to view the 74880 baud bootloader messages from the ESP-8266 on Ubuntu. While it isn't fully integrated into a terminal emulator, it gets the job done.

Using a small program and an FTDI based serial port adapter I can now view the bootloader messages from ESP-8266s.
