Your AI hardware partner

Bring an idea or files. Leo designs a complete ESP32 PCB project — schematic through Gerber — and writes the firmware that has to run on it. DFM, first bring-up, or a path the next batch can repeat. A purchase order is not required to talk.

What this lab designs and writes

Taken from boards and firmware already built here. Say which of these you need.

Hardware we design

Complete schematic and PCB in Altium: MCU, power, sensors, RF keep-out, BOM and Gerber ready to order
Motion and heading: IMU and magnetometer; GNSS on UART
Keys, LEDs, buzzer, vibrator, I2C GPIO expanders
SPI TFT (ST7789 class), SD / TF card, I2S speaker (MAX98357 class)
Wi-Fi / BLE module layout, and short-range radio on the same board
Wearable-class boards: battery, IMU, GNSS and keys on one PCB

Firmware we write

ESP-IDF on ESP32-S3 / C6 / C3, from first UART through product logic
Wi-Fi + BLE, including phone BluFi provisioning
I2C / SPI sensors, GNSS, PWM, GPIO power rails
On-device HTTP file server, SD card, TFT UI, keys, encoder, haptics
Multi-board UART: a master plus organ modules
OTA, NVS, power and sleep; I2S audio; HTTPS when the product talks to a cloud API

What you can ask us to do

Design a complete ESP32 schematic and PCB from a product note
Write the ESP-IDF firmware that has to run on that board
Add IMU, GNSS, display, SD, audio, Wi-Fi or BLE to the product
Review Gerber and BOM you already have
Bring up the first article and leave a flash-and-test path
Wire a controller board to satellite modules over UART

Four packages. Not an open-ended project.

Say design, DFM, bring-up, or repeatable when you write.

01 Schematic and PCB design

A complete ESP32 / S2 / S3 / C3 / C6 PCB project from the product note: schematic, layout, BOM and Gerber. Day-to-day work here, not a one-off sketch.

You get schematic, PCB, BOM, and files that are ready to order.

02 DFM review

Your schematic or layout, checked against parts you can actually buy, footprints, power, and assembly.

You get a punch list and files that are safe to order.

03 First bring-up

Board back from fab. Power rails, flash path, first UART, first I2C or SPI. Firmware we wrote, or yours, talking on the bench — the faults that usually hide until then.

You get a log, a known-fault list, and a short video of it running.

04 Repeatable path

The same steps the next batch can follow, so bring-up is not a one-off heroics session.

You get a flash script, power-on checks, and a written definition of pass.

We take

ESP32 / S2 / S3 / C3 / C6 as the main MCU
A complete schematic and PCB project in Altium, 2–4 layer
ESP-IDF firmware: Wi-Fi / BLE, sensors, display, OTA
AI-generated files, hand-drawn files, or only a product note
Technical exchange without a purchase order

We do not take

Automotive, medical, or radio certification as the job
FPGA or a non-ESP32 family as the main MCU
Plastic tooling before the board is frozen
Any idea on a non-ESP32 stack, or an unbounded ‘do everything’ product

Inside an accepted job

Complete schematic and PCB project on ESP32 / S2 / S3 / C3 / C6
ESP-IDF firmware: from official examples to product logic
IMU, GNSS, TFT, SD, I2S, BluFi, or multi-board UART when the product needs them
DFM punch list: footprints, power, assembly, parts you can buy
First bring-up: rails, flash, UART, I2C / SPI
A repeatable flash-and-test path for the next batch

Usually discussed separately

Plastic tooling and enclosure design — after the board is frozen
FCC / CE lab filing — we design with certification in mind; the certificate is a separate step
High-volume SMT on other chip families — this lab is ESP32-first

See the PCB process — Leo designs schematic and layout, and reviews the same sequence a fab and SMT line will run. We do not run a factory. This is what the board has to live through.

把 AI 创意给你落地

可以只有想法，也可以已有文件。Leo 做完整的 ESP32 PCB 项目——从原理图到 Gerber——并写板上要跑的固件。可制造审查、第一次点亮，或留下下一批能重复的路径。没有采购单也可以先聊。

这个实验室实际在画、在写的

从已经做过的板和固件里列出来。写信时直接说要哪几条。

硬件设计

用 Altium 做完整原理图和 PCB：主控、电源、传感器、射频净空、BOM 和可下单 Gerber
运动与航向：IMU、磁力计；UART 上的 GNSS
按键、LED、蜂鸣器、马达振动、I2C 扩展 IO
SPI TFT（ST7789 一类）、SD / TF 卡、I2S 喇叭（MAX98357 一类）
Wi-Fi / BLE 模组布局，以及同一块板上的短距射频
可穿戴一类：电池、IMU、GNSS、按键做在同一块 PCB

固件编写

ESP32-S3 / C6 / C3 上的 ESP-IDF，从第一次串口写到产品逻辑
Wi-Fi + BLE，含手机 BluFi 配网
I2C / SPI 传感器、GNSS、PWM、GPIO 电源轨
板上 HTTP 文件服务、SD 卡、TFT 界面、按键、编码器、振动
多板 UART：一块主控加若干外设模块
OTA、NVS、电源与休眠；I2S 音频；产品要连云时的 HTTPS 客户端

客户可以直接找我们做的

从产品说明画完整的 ESP32 原理图和 PCB
写这块板上要跑的 ESP-IDF 固件
给产品加上 IMU、GNSS、屏、SD、音频、Wi-Fi 或 BLE
审查你已有的 Gerber 和 BOM
点亮首件，并留下可重复的烧录测试路径
用 UART 把主控板和外设模块连成一套

四个套餐。不是敞开口的项目。

写信时直接说：设计、审查、点亮，还是可复现。

01 原理图与 PCB 设计

从产品说明做完整的 ESP32 / S2 / S3 / C3 / C6 PCB 项目：原理图、布局、BOM 和 Gerber。这是日常工作，不是偶尔画一张。

交付：原理图、PCB、BOM，以及可以下单的文件。

02 可制造审查

原理图或 PCB，对照能买到的料、封装、电源和装配，改到可以下单。

交付：问题清单，以及可以下单的文件。

03 第一次点亮

板从工厂回来。电源轨、烧录、第一次串口、第一次 I2C 或 SPI。我们写的固件，或你的固件，在台架上通上——那些不上台架看不见的故障。

交付：上电日志、已知故障清单、一段现场视频。

04 可复现路径

下一批还能按同样步骤走，点亮不再靠某一次运气。

交付：烧录脚本、上电检查，以及书面的合格标准。

接

主控是 ESP32 / S2 / S3 / C3 / C6
用 Altium 做完整原理图与 PCB 项目，2–4 层
ESP-IDF 固件：Wi-Fi / BLE、传感器、显示、OTA
AI 出的文件、手画的文件，或只有产品说明
没有采购单也可以技术交流

不接

车规、医疗，或以射频认证本身为交付
FPGA 或其他芯片家族当主控
板还没定就开模做外壳
非 ESP32 栈，或不限定芯片的「什么都做」

接单后会做的事

ESP32 / S2 / S3 / C3 / C6 完整原理图与 PCB 项目
ESP-IDF 固件：从官方案例写到产品逻辑
产品需要时做 IMU、GNSS、TFT、SD、I2S、BluFi，或多板 UART
可制造审查：封装、电源、装配、能买到的料
第一次点亮：电源轨、烧录、UART、I2C / SPI
下一批能重复的烧录和测试步骤

一般需要另谈

开模和外观 — 等板定稿后再说
FCC / CE 送检出证 — 设计会按认证考虑，证书是另一步
其他芯片的大规模贴片 — 这里以 ESP32 为基准
