SPSGRF 6 Hardware design notes SPSGRF-868 and SPSGRF-915 modules support SPI hardware interfaces. Notes All unused pins should be left floating; do not ground. All GND pins must be well grounded. The area around the module should be free of any ground planes, power planes, trace routings, or metal for 6 mm from the module antenna position, in all directions. Traces should not be routed underneath the module.
