Hardware layout and configuration

The B-L462E-CELL1 Discovery kit for IoT nodes is designed around the LBAD0ZZ1SE Murata module. The
hardware block diagram (Refer to 

Figure 2

) illustrates the connection between LBAD0ZZ1SE and peripherals:

OLED screen, sensors, USB FS connector, USARTs, audio, EEPROM, micro SIM card, and embedded ST-LINK/
V2-1. 

Figure 3

 and 

Figure 4

 help the user to locate these features on the B-L462E-CELL1 Discovery kit for IoT

nodes. 

Figure 5

 and 

Figure 6

 give the mechanical dimensions of the B-L462E-CELL1 board.
