Microduino-nRF24 uses the newest 2.4GHz transceiver nRF24L01 from Nordic Semiconductor. This transceiver IC operates in the 2.4GHz band and has many new features! Take all the coolness of the nRF2401A and add some extra pipelines, buffers, and an auto-retransmit feature.

Designers can use Microduino-nRF24 in project without any wireless design , and just need to stack it with Microduino-Core or Microduino-Core+ through UPin-27, the standard Microduino interface will attach nRF24 and MCU with SPI bus, on transferring data.

Microduino-nRF24 works in the 1.9 to 3.6v voltage, the on-chip DC-DC regulator will automatically step down supply voltage to proper level.

Note: We now populate these boards with the nRF24L01+. The '+' version of the IC has improved range, sensitivity, and data rates. The command set is backward compatible with the original nRF24L01.


Features

  • Worldwide license-free 2.4GHz ISM band operation
  • Using the U-Shape 27-pin interface (UPin-27), the standard interface of Microduino
