Physical Installation
For maximum range, it is recommended that the RM1 radio module is installed perpendicular to the host PCB. Connection is made using a right-angled, dual row, 24 pin, 1.27mm pitch pin header Example host PCB footprint and radio module pinout are shown below including ground pads. It is recommended that the radio module pin header is soldered directly into plated through holes on the host PCB however a suitable pin socket can be used.
Host PCB Footprint:
For EMC purposes, it is recommended that the host ground pads are soldered to the corresponding ground pads on the radio module:
