ESP32 Dev Boards PCB

- ピンヘッダは ESP32-S3-DevKitC 互換の配置 - 10 ピンブレッドボードに挿しても、左右 1 ピン空いている - ESP-Prog の USB シリアル変換のボックスピンヘッダを持つ - USB Type-C を持つ

BOOTH でモジュール付きキットを販売中です https://74th.booth.pm/items/4179263

- 10 ピンブレッドボードに刺すと、片方使えなくなるから。 - MicroUSB ではなく USB Type-C で使いたいから。 - USB シリアル変換 IC が別になっている方が、ボード単体で使う時に消費電力が下がるから。

ピンヘッダのアサインは ESP32-S3-DevKitC v1.1 互換のため、こちらを確認下さい。

ESP32-S3-WROOM-1: common questions

What microcontroller does the ESP32-S3-WROOM-1 use?

The ESP32-S3-WROOM-1 is built around the ESP32-C3-MINI-1, from the ESP32 family.

How big is the ESP32-S3-WROOM-1 PCB?

The ESP32-S3-WROOM-1 measures 25.4 × 51.3 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the ESP32-S3-WROOM-1?

19 components, from 19 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-WROOM-1 design files?

From the 74th/esp32-dev-boards 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-WROOM-1 design in my own project?

Yes, under the terms of its MIT license, which 74th chose for the repository.

Can I test firmware for the ESP32-S3-WROOM-1 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.
