About the Curtains PCB

Curtains is an open source ESP32 PCB design by fujiy, published on GitHub. It is a 2-layer board measuring 30 × 50 mm, with 19 components from 15 distinct parts.

Its main chip is the ESP32-C3-WROOM-02, from the ESP32 family. Other key parts include the LM2842X and ULN2803A. By type, the board carries 7 resistors, 3 ICs, 2 connectors, 2 capacitors, 1 switch and 1 LED.

It belongs with the iot & wireless designs in this gallery.

From the project

Curtains は ESP32-C3-WROOM-02 と 2 系統のステッピングモーターを使ったカーテン/ロールスクリーンコントローラーです。現在は ESPHome + Home Assistant 構成です。ESPHome の ESP32 framework は、既存 HomeSpan 実装と近い arduino を使います。

- Home Assistant には各デバイスが ESPHome API 経由で接続される - 1 台あたり Curtain A / Curtain B の 2 つの cover エンティティを公開 - 移動範囲の下限/上限と反転設定を Home Assistant から変更可能 - 下限/上限/現在位置/反転設定を ESP32 の preference に保存し、再起動後も復元 - 物理ボタンによる既存の設定モードを維持 - 移動停止時はモーター coil 出力を off

Curtains: common questions

What microcontroller does the Curtains use?

The Curtains is built around the ESP32-C3-WROOM-02, from the ESP32 family.

How big is the Curtains PCB?

The Curtains measures 30 × 50 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Curtains?

19 components, from 15 distinct parts. The full bill of materials is listed on this page.

Where can I download the Curtains design files?

From the fujiy/Home repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Curtains design in my own project?

The repository has no license, so all rights stay with fujiy. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Curtains without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
