Commercial Use - Custom Firmware Request for DF2301QG

Hello DFRobot Community & Team!

I'm deploying DF2301QG modules commercially and need your help/advice.

🏢 COMPANY: MiRDEV Otomasyon & Teknoloji (Turkey)
📺 DEMO: https://www.youtube.com/shorts/jmpkFY0C8ww

PROJECT:
- Voice-controlled relay systems for factories/offices
- Raspberry Pi Pico + DF2301QG (UART mode)
- 10-15 modules per installation
- Expected: 100+ modules/year

THE PROBLEM:

Training 15 modules × 17 commands = So Many Times! 

WHAT I NEED:
Custom firmware with pre-programmed commands for bulk orders.

QUESTIONS:
1. Does DFRobot offer custom firmware for commercial customers?
2. What's the MOQ (minimum order quantity)?
3. Has anyone solved this differently?

I'm ready to:
✅ Place bulk orders (100+ units)
✅ Share technical implementation with community

Any advice or DFRobot contact for commercial inquiries?

Thanks! 🙏
