We've spent 10 years building projects for makers, schools, and institutions across India. Ships from Bengaluru in 3-5 days. If defective on arrival, replace within 7 days.\u003c\/p\u003e\n\n\u003cdetails\u003e\u003csummary\u003eIs this compatible with Arduino IDE?\u003c\/summary\u003e\u003cp\u003eYes. Install the ESP32 board package through Boards Manager and select “ESP32 Dev Module”.

The ESP32 handles automatic time‑slicing, so dual‑mode applications work well.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eWhat is the typical Bluetooth range?\u003c\/summary\u003e\u003cp\u003eIn open air the range is about 10 m for BLE and similar for Classic Bluetooth. Walls and interference can reduce it; adding an external antenna (if the module supports it) can extend range.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdiv class=\"compoden-handoff\" style=\"margin-top:24px;padding:16px;background:#f0f4ff;border-left:4px solid #2B4D8F;border-radius:4px;\"\u003e\n  \u003cp style=\"margin:0 0 6px 0;font-weight:600;color:#1A3560;\"\u003e📦 Free Setup Handoff Document Included\u003c\/p\u003e\n  \u003cp style=\"margin:0;font-size:0.95em;color:#333;\"\u003eEvery Compoden order includes a free setup handoff document — step-by-step instructions to get your component working within minutes.
