Figure 3-2 shows a footprint of the 1323x-MRB with the location of the IO Headers J2 and J3. The user
may desire to create a motherboard on which the 1323x-MRB would be mounted, and headers J2 and J3
are used for connection to the motherboard:
• Both headers have standard 0.10in / 2.54 mm pin spacing
• J2 is 20-pin and J3 is 18-pin
• Both are pin headers mounted on the bottom side of the 1323x-MRB and are intended to plug into
matching receptacles on the motherboard.
• It is recommended that 1323x-MRB be located such that it extends beyond edge of the
motherboard (see Figure 3-2) so that the entire F-Antenna is exposed with no motherboard ground
or voltage plane beneath it. This is to allow best results transmitting and receiving with the radio.
• With the 1323x-MRB oriented as shown in Figure 3-2, the IR blaster transmits to the right.
