Arduino-Compatible RF-Nano V3 - ATmega328 with NRF24L01 Integrated volume control Product Altimeter Barometric Pressure AltitudeArduino Nano with an NRF24L01+ radio baked onto the same board. Saves you the wiring and the SPI header juggling when you want a Nano that talks wireless out of the box. Program it exactly like a Nano from the Arduino IDE over micro USB. The 2. 4GHz radio does the usual NRF24 tricks: multi channel, dynamic payload, auto ack. Good for remote controls, sensor nodes, and small mesh setups. Specs MCU ATmega328, 16MHz Memory 32KB flash (2KB bootloader),
