Package include:

Installing an external antenna (special scenario):
1. The boards are equipped with onboard antennas, with a normal distance of 10-15 meters. If they are installed in a metal shell (which will block the signal) or increase the Bluetooth distance (20-30 meters), external antennas will be used.
2. Customers are required to purchase 2.4G antennas (antenna extension cables, antenna rods) on their own, and this product does not include external antennas.
