Ebay seems infested with these cheap interface boards that use a STC15L204EA microcontroller (A 51 series, I believe) to do all the heavy lifting when driving the cheap and effective NRF24L01 transceivers, like this ad: http://www.ebay.co.uk/itm/2-4GHz-NRF24L01-Wireless-Transceiver-Module-Shield-SPI-to-UART-Interface-/400953959334?hash=item5d5ab7e3a6:g:IFoAAOSwBahVETo0
Date is spare to non existent, other than that they seem to operate at a fixed 115k baud, bidirectionally. They are cheap enough to buy some to play with, but I'm wondering if anyone here has already had a go with them.
On the face of it they seem very limited, and may only be usable as a pair, as there is no mention of any functionality to change the parameters on the NRF24L01. This seems a bit odd, as having gone to the trouble of making a working serial UART to SPI interface for the NRF24L01 it would seem relatively easy to incorporate the ability to send commands to change the channel, baud rate, qualifier etc.
My question is, has anyone used these modules, please?
I've done a search, and it seems some have spent many hours driving the rather complex NRF24L01 modules, but I can't see any reference to these add-on boards.
