NRF24L01 + 2.4Ghz wireless module + SMA antenna + PA + LNA. The NRF24L01 + is a 2.4 GHz transceiver with a built-in hardware protocol (Enhanced ShockBurst ™), made for ultra-efficient wireless applications. The nRF24L01 uses the 2,400 - 2.4835GHz band to communicate. This module can be accessed with the Serial Peripheral Interface (SPI). The configuration registers of the module can also be changed via SPI. The NRF24L01 + module is the upgraded version of the NRF24L01, this module also has a "long-distance mode" with 256kbps, in addition 2 ground and 2 3.3V pins have been merged. This version has an external antenna, power amplifier (PA) and a low noise amplifier (LNA), making the range of the NRF24L01 module even larger than the module with only the external antenna. https://elecena.pl/product/27738537/opencircuit-nrf24l01-2-4ghz-wireless-module-sma-antenna-pa-lna 2025-01-22 https://elecena.pl/product/27738537/opencircuit-nrf24l01-2-4ghz-wireless-module-sma-antenna-pa-lna 2025-03-22 https://elecena.pl/product/27738537/opencircuit-nrf24l01-2-4ghz-wireless-module-sma-antenna-pa-lna 2025-05-29 https://elecena.pl/product/27738537/opencircuit-nrf24l01-2-4ghz-wireless-module-sma-antenna-pa-lna 2026-02-23 https://elecena.pl/product/27738537/opencircuit-nrf24l01-2-4ghz-wireless-module-sma-antenna-pa-lna 2026-02-25 https://elecena.pl/product/27738537/opencircuit-nrf24l01-2-4ghz-wireless-module-sma-antenna-pa-lna 2026-04-08 https://elecena.pl/product/27738537/opencircuit-nrf24l01-2-4ghz-wireless-module-sma-antenna-pa-lna 2026-04-14 https://elecena.pl/product/27738537/opencircuit-nrf24l01-2-4ghz-wireless-module-sma-antenna-pa-lna 2026-04-25
