SIM900 Antenna


#1

So I finish populating the board and I need to test the cell module but doh - no antenna…

I know - Tweezers are made of the finest antenna material know to man :smiley:

Network status light
64ms On / 800ms Off - SIM900 not registered on the network
64ms On / 3000 Off - SIM900 registered on the network

Tweezers work a treat connecting to the Vodafone network :whistle:
