I have recently purchased a KC Wirefree 21 from your site. Upon receiving the module, i was quite shocked by it is very small in size, a lot smaller than i thought it would be, and it comes with another problem.
How do I make connection to other device like a microcontroller or transceiver?
Does it have any special socket to accommodate the module? Some suggest direct solder the copper wire to the I/O of the module, but will it damage the module?
Any other suggestion please? Thanks a lot in advance.
