LGT RF Nano V2.0 Wireless Module Integrated NRF24L01

The LGT RF Nano V2.0 Wireless Module runs at the same core as a standard Arduino Nano — same 32 KB flash, same 2 KB SRAM, same pin layout. What changes is the CC2540 Bluetooth chip sitting alongside it. The CC2540 handles BLE 4.2 communication independently, so the microcontroller does not burn processing cycles managing the wireless stack. That separation keeps your sketch responsive even when the BLE-Nano 4.2 Development Board is actively transmitting data to a phone or gateway.

The CC2540 is a well-documented Texas Instruments chip used in production IoT hardware, not a generic clone module. BLE 4.2 supports faster pairing, better packet encryption, and improved throughput compared to BLE 4.0. The board runs on 5V through a Type-C connector, which removes the older micro-USB friction most bench setups deal with. One trade-off — BLE 4.2 is not backward compatible with classic Bluetooth devices. It works with smartphones and BLE-capable hosts only, not older Bluetooth speakers or legacy serial adapters.

With 22 digital I/O pins including 6 PWM lines and 8 analog inputs, this rf module arduino fits projects that need both sensing and wireless output in one board. The Integrated CC2540 bluetooth chip makes it a compact choice for wireless control and IoT device prototyping without stacking a separate rf module arduino shield. Available from StemVolt, this unit is suitable for engineers working on battery applications and practical electronics projects.
