NRF24L01+ 2.4GHz Wireless Data Transceiver Modules

摘要

Connecting a couple of Arduino, Micromite or other popular micros via a wireless data link can be done by making use of a pair of low-cost modules, based on Nordic Semiconductor's ultra-low-power nRF24L01+ chip. There are quite a few of these modules around, most of them costing just a pound or so, with the more expensive units generally giving longer range (often due to a better antenna). (At the time of publication, a typical example is eBay item 143005028113, available for 99p each including postage.) This circuit used an nRF24L01+ module, available with a whip antenna.
