Looking for a tiny radio that can talk far and still connect to a phone? The RAKwireless RAK11720, LoRa Bluetooth Module without MHF4 900MHz gives you both long-range LoRa and low-energy Bluetooth in a 15 15 mm stamp. It solves the common problem of needing two separate chips, saving board space and design time. If you have been struggling with weak signals or complex wiring, this module is the shortcut you need.
RAKwireless RAK11720, LoRa Bluetooth Module without MHF4 900MHz
Many IoT projects require both long-range data and quick local control, yet designers often buy separate LoRa and BLE chips. That adds cost, increases power draw, and makes firmware integration harder. The problem matters because it slows product launch and raises the risk of bugs. This module merges a Semtech SX1262 LoRa chip with a Bluetooth 5.0 radio on a single MCU, giving you a clean, low-power solution that works on US915, AU915, KR920 and AS923 bands.
