About the Esp32-s3-thermostat box PCB

Esp32-s3-thermostat box is an open source ESP32 PCB design by kenfrew980, published on GitHub under the Apache-2.0 license. It is a 2-layer board measuring 100 × 75 mm, with 64 components from 40 distinct parts.

Its main chip is the ESP32-S3-WROOM-1-N8R8, from the ESP32 family. Other key parts include the HLK-5M05, AP2114H-3.3 1A, DS18B20 防水探头, PC817 and PCF85063. By type, the board carries 22 resistors, 12 capacitors, 6 ICs, 4 transistors, 4 connectors and 3 diodes.

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

From the project

ESP32-S3 智能恒温箱：PID 温控 + 触摸屏 UI + 网页远程控制 + 自研 PCB

这块板要把这些东西集成到一起：220V 输入与隔离电源 + ESP32-S3 主控 + 2.8″ 触摸屏 + 测温 + RTC + SSR 加热控制，替代现在用的 Waveshare ESP32-S3-Touch-LCD-2.8 开发板。

装扩展（只需一次） > 高级 → 扩展管理器 → 导入 → 选 lceda-nettoolsv.eext → 启用

导入 > 打开原理图编辑器 → 菜单 网表工具 → 导入网络表 > 选 恒温箱主板.enet

扩展会把 64 个器件按方阵摆到画布上、每个引脚拉出短线并标上网络名。同网络的引脚自动连通，然后 设计 → 转换原理图到PCB，PCB 就有完整飞线了。

两种导入模式： - 导入网络表 — 引脚拉短线 + 贴网络标签（图面干净，改起来方便） - 导入网络表(连线) — 同网络之间直接用导线连起来（更接近传统原理图）

Esp32-s3-thermostat box: common questions

What microcontroller does the Esp32-s3-thermostat box use?

The Esp32-s3-thermostat box is built around the ESP32-S3-WROOM-1-N8R8, from the ESP32 family.

How big is the Esp32-s3-thermostat box PCB?

The Esp32-s3-thermostat box measures 100 × 75 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Esp32-s3-thermostat box?

64 components, from 40 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Esp32-s3-thermostat box design files?

From the kenfrew980/esp32-s3-thermostat-box repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the Esp32-s3-thermostat box design in my own project?

Yes, under the terms of its Apache-2.0 license, which kenfrew980 chose for the repository.

Can I test firmware for the Esp32-s3-thermostat box 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.
