I have bought this module with complete development kit 2006-2007(4 year back)... That also include ICSP Programmer. I want to find that development kit, I am specially interested in the documentation and ICSP programmer for that kit. I am unable to find that development board (the one that i found is with USB programmer) I think administrator removed that link... I still have the hardware excluding ICSP programmer... I want to use it for some other project. Plz guide how can I find those the requested material... Thank you</p>

<br /><br>
I think I make a very bad mistake. I pump in 5V for a few second (or may b a few minutes) but how could I know it is still working?<br /><br>
<br /><br>
Thanks,<br /><br>

I come from New Zealand (i.e. I use the metric system all the time), and even I had no idea what it stood for. Sparkfun: correct SI style is to use 'm' to represent meters; preferably with a space between the number and the unit.</p>

Has anyone used this, or any other long range and high-speed wireless transmitters with a Cypress PSoC? Sparkfun has lots of code for the AVR's, but I would prefer to use the PSoC since it can be ordered for free from Cypress.</p>

dav7 on WRL-00151 - Transceiver nRF2401A with Trace Antennadav7urn:uuid:7ce84e63-8b16-b4c0-5185-86a2ff5feea12009-05-22T07:03:49-06:00<p>This module has a FIFO (first in first out) buffer that you can fill with data at any rate (so you don't need a fast microcontroller), then you set a transmit bit and it sends it out at 250kbps or 1Mbps depending on how you've configured it.<br>
Page 21 in the RF-24G PDF above lists the following as the payload size:<br>
- In Shock-Burst mode payload size is 256 bits minus the following: (Address: 8 to 40 bits. + CRC 8 or 16 bits).<br>
- In Direct mode the payload size is defined by 1Mbps for 4ms: 4000 bits minus the following: (Preamble: 8 (or 4) bits. + Address: 8 to 40 bits. + CRC: 0, 8 or 16 bits).<br>
So unless I'm wrong, you at worst have 200 bits - ie 25 bytes - to work with. The whole transmission itself is a bit bigger - the payload is just one of 4 "pieces" of a transmission (which are all mentioned in the PDF).<br>
If I'm wrong, please do correct me! Also, listing the buffer size in the specs would probably be very convenient ;)</p>

Very easy to use, excellent example code. Descriptive paragraph should probably read "data is shot towards the receiving module at 1 million BITS per second."</p>

Hard to troubleshoot, but the example code is helpful. I used 3.4~3.7V for a few weeks, and burned out two of them. Stay below 3.3V!</p>
