Overview

Barn blinds controller is an open-source printed circuit board by irvintim, from the irvintim/barn-blinds-controller repository on GitHub. It is a 4-layer board of 65 × 73.9 mm with 118 parts on 101 nets, routed with 526 tracks and 177 vias.

It is built around the ESP32-S3-WROOM-1-N8, ACS725LLCTR-05AB-T and TMP235EVM, with the PRTR5V0U2X, ISO7760DBQ and AMS1117-3.3 among its other parts. Its parts include 43 capacitors, 24 resistors, 16 ICs, 10 diodes and 4 transistors. It belongs with the ESP32 boards of this library.

Open barn-blinds-controller.kicad_pro. Everything the project needs is under this folder: lib/New_Library.kicad_sym (U1, J4, TMP235), lib/barn_shade_controller.pretty/, and lib/3dmodels/ (referenced as ${KIPRJMOD}/lib/3dmodels/...). Standard KiCad libraries plus the Espressif and JLCPCB PCM add-ons supply the rest.

  • fab/vsp-wsc4-rev1.2/, fab/vsp-wsc4-rev1.3/: the files each order was built from. Rev 1.3 order notes: fab/vsp-wsc4-rev1.3/JLCPCB-ORDER-NOTES.md.
  • jlcpcb-export-steps.md: how to generate and archive a fab set.

  • lib/artwork/: silkscreen graphics sources.

Checks (from WSL, run in this folder):

"$K" sch erc --output erc.rpt --severity-error --severity-warning barn-blinds-controller.kicad_sch   # 92 violations, 5 errors, all known
"$K" pcb drc --output drc.rpt --severity-error barn-blinds-controller.kicad_pcb                      # 0 / 0
git status   # kicad-cli can rewrite files, so check after every run

Branches: Rev 1.3 fixes go on release/v1.3; Rev 1.4 work on main (ADR-020). Never move a vX.Y-fab tag (ADR-016).

Questions

How big is the Barn blinds controller PCB?

It measures 65 × 73.9 mm and has 4 copper layers, 1.6 mm thick.

What parts does the Barn blinds controller use?

118 parts, built around the ESP32-S3-WROOM-1-N8, ACS725LLCTR-05AB-T, TMP235EVM and PRTR5V0U2X. 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 Barn blinds controller KiCad files?

From the irvintim/barn-blinds-controller repository on GitHub, at the commit this page was made from: the board is pcb/main-board/barn-blinds-controller.kicad_pcb and its schematic pcb/main-board/barn-blinds-controller.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Barn blinds controller design in my own project?

Its repository states no licence, so its author keeps all rights: ask irvintim before reusing the design.
