Oddly, I've been looking at exactly those modules - the nRF24L01+ modules are astonishingly good value for money - I just bought a bunch from http://imall.iteadstudio.com/catalogsearch/result/?q=NRF24L01+ - 2 of each type - my application may need the longer range of the LNA/PA version, but for that sort of money I just bought a pair to try out. The Nordic stuff is excellent and longer range generally than the 802.15.4/ZigBee stuff, though I;ve noticed that TI do SoCs with inbuilt wireless but normally with an ARM core - the MSP430 variants are <1GHz. So many extraordinarily cheap neat devices out there... -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
