Samtec headers arrived

Samtec TFM-110-01-L-D-AAs I already wrote in a comment of my previous posting, I was quite unhappy with the Anaren A1101R08A-EM1 evaluation module, as the spacing of the socket connector is 0.05 inch and the socket is quite to narrow to put in a test wire in a reliable way.

Possible solution: I ordered the counterpart to the socket connectors, two Samtec TFM-110-01-L-D-A 050″ Tiger Eye™ High Reliability Terminal Strip. Unfortunatelly, I wasn’t allowed to directly order it at Farnell as a private person, but I had to go through Heinz Büchner Elektronik (Berlin). The picture above shows these Terminal Strips.

What’s next: Design a PCB to which to solder this terminal stips and connect them to a 2×13 pin socket suitable to plug into a Raspberry Pi.

Evaluation module with Anaren A1101R08A radio module

a1101-2500emiToday I ordered a evaluation module with an Anaren A1101R08A radio module for approx. €30 (excluded shipping costs). This explicitly works in the 868MHz band and it should be easy to replace the RF module I used before. http://de.mouser.com/ProductDetail/Anaren/A1101R08A-EM1
