CC256XEM Connectors

The twin 2×10 headers, JR1 and JR2, interface with the connectors RF1 and RF2, respectively, of a
CC256XEM board (CC256XQFNEM, CC2564MODAEM, or CC2564MODNEM).

Table 2-1

and

Table 2-2

are divided into the pins and functions on the CC256XEM-STADAPT board seen

in the data sheet or schematics, and the corresponding pins and functions on the CC256X EM boards.
