About

Bluetooth & Wireless Modules — HC-05, HC-06, NRF24L01, LoRa, 433MHz Wireless communication modules add cable-free connectivity to Arduino and microcontroller projects — from short-range Bluetooth remote control to long-range LoRa sensor networks. This collection covers the full range of wireless modules available at Keszoox. Bluetooth Modules HC-05: Classic Bluetooth 2.0, master/slave configurable, UART interface — for Arduino-to-Android communication and robot remote control HC-06 / BT-06: Classic Bluetooth 2.0, slave-only, UART — simpler alternative to HC-05 for receive-only applications HM-10 / AT-09 BLE 4.0: Bluetooth Low Energy, CC2540/CC2541, iOS and Android compatible — for low-power BLE sensor beacons 2.4GHz Wireless NRF24L01+ (with PA+LNA): 2.4GHz transceiver, SPI interface, up to 1km range with PA+LNA version — for multi-node sensor networks and RC control LoRa Long-Range RA-01/RA-02 SX1278 433MHz: LoRa spread-spectrum, up to 10km range in open areas — for remote sensor nodes, agriculture monitoring, and asset tracking 433MHz ASK/OOK SYN115/SYN480R 433MHz: Simple amplitude-shift keying transmitter/receiver pair — for basic remote control and simple data links Wireless Module Selection Guide Android/iOS app control: HC-05 (classic BT) or HM-10 (BLE) Multi-node sensor network (<100m): NRF24L01+ Long-range IoT (>1km): LoRa SX1278 433MHz Simple remote control: 433MHz ASK transmitter/receiver All wireless modules are in stock and compatible with Arduino, ESP32, and Raspberry Pi.
