Dibutuhkan Engineer ESP32 untuk Pembuatan Board Controller Pattern Multi Channel (PCB + Firmware)

@mahmoudralizadeh

​Hi there, ​I’ve gone through your requirements for the ESP32 multi-channel controller. Since I’ve been working on this platform since 2019 and have a solid background in PCB design and firmware (with a 4.5-star rating here), I’m confident I can build exactly what you need. ​I’ve done similar board designs before where stability and "glitch-free" operation were critical. Here is how I plan to handle your project: ​The Hardware Side: To get 32 stable outputs from an ESP32, I’ll use a 74HC595 shift register chain paired with ULN2803 driver arrays. This is the most reliable way to handle the LOW triggers for your 12V relays without stressing the MCU. I’ll also integrate a proper Buck Converter to step down the 12V supply to a clean 3.3V, keeping the board stable for long runs. You’ll get the full Gerber files, schematics, and BOM. ​The Logic & Patterns: I’ll write the firmware in a non-blocking way (using a state machine). This is key because the light patterns need to run smoothly while the ESP32 is also handling the Web Interface and listening for the 433MHz RF remote. ​Patterns: I’ll code the 30+ patterns to be "dynamic," meaning they’ll automatically adjust whether you set the system to 4 channels or 32. ​Interface: The web-based dashboard will be lightweight and mobile-friendly for easy control of speed, mode, and factory reset. ​What I’ll deliver: ​Clean, production-ready PCB files. ​Well-commented Arduino-based source code. ​A simple PDF guide for wiring and setup. ​I have some of my previous PCB layouts in my portfolio that I can show you in chat. I’m ready to start and can get the first draft of the schematic ready pretty quickly. ​Looking forward to hearing from you!

Hello Dika, I can design and develop a custom ESP32 board controller for your multi-channel pattern control system, ensuring precise and efficient control over 30+ pattern types with scalable output up to 32 channels ?. My approach: Design the PCB layout and firmware using Arduino IDE, implementing a step-down converter (e.g., 12V to 5V/3.3V), ULN2003/ULN2803 driver, 74HC595 shift register, and transistor array to achieve a stable and glitch-free system. I'd love to share my previous experience in designing similar boards and firmware. Are you available for a quick chat? Kind regards, - Abdul

Saya adalah seorang Electronics Engineer berpengalaman dalam desain board berbasis ESP32, termasuk sistem ekspansi output hingga 32 channel menggunakan kombinasi shift register (seperti 74HC595) dan driver sink array (ULN2803 atau transistor/MOSFET), serta desain power supply step-down 12V yang stabil untuk aplikasi relay. Untuk proyek ini, saya akan merancang arsitektur hardware yang scalable, stabil terhadap noise switching relay, dan menghasilkan output LOW trigger yang bebas glitch, dengan buck converter efisien serta filtering yang memadai. Firmware akan dibangun menggunakan arsitektur non-blocking berbasis state machine dan timer sehingga seluruh pattern, mode manual/auto, pengaturan speed tanpa reflash, standby, pass beam, factory reset, serta kontrol Web (WiFi) dan RF 433MHz dapat berjalan stabil dan responsif. Saya akan menyediakan skematik lengkap, file PCB, Gerber siap produksi, source code firmware penuh, serta dokumentasi pinout, struktur pattern engine, dan sistem kontrol. Estimasi pengerjaan sekitar 3–4 minggu termasuk tahap pengujian dengan modul relay nyata, dan saya siap untuk kerja sama jangka panjang serta memberikan contoh proyek ESP32 sebelumnya jika diperlukan.
