RF Transceiver Module...

As mentioned by 9W2DTR, the RF transceiver modules we ordered have arrived. It's a 433MHz module capable of max speed of around 115 kbps, tx power of 7dBm and SPI interface.

Since I'll be doing my development on a prototyping board, I needed a way to mount the module. The module's headers are 0.5mm, 2.0mm pitch whereas a standard prototyping boards are 0.1" pitch. A quick clicking on Eagle, and a few minutes later, the adaptor was born. Photo above shows the RF module mounted onto the prototyping adapter and it is sitting on top of the Futurlec PIC18F4550 development board. The 0.1" headers are reverse mounted on the PCB, i.e., the header protrude on the solder side instead of the component side. The loose module and adapter PCB are infront of the mounted module.

Photo below shows how the module looks once mounted to the prototyping board. There are still two (2) holes on either side of the headers to allow for jumper wires.

Bro,

That's a nice and neat one...
