Figure 2: Block diagram of EVK-R8  

The EVK-R8 is formed by three boards: 

 

The lower one, called EVB-WL3 or simply EVB, contains the power supply and other peripherals for 
the cellular module (such as SIM card holder, reset button and power-on button). 

 

The LENA-R8 adapter board, called ADP-R8, contains the LENA-R8 module, the cellular antenna 
connector (ANT), the cellular USB 

native

 connector (J700), the cellular USB boot slide switch 

(J200), the cellular USB 

two UARTs

 connector (J201), the cellular UARTs routing switch (J601), 

the cellular VCC jumper (J102), an audio codec, the LENA-R8001M10 GNSS antenna connector 
(ANT_GNSS), the LENA-R8001M10 VCC_GNSS enable jumper (J701), and the LENA-R8001M10 
VBCKP_GNSS enable jumper (J702). 

 

The GNSS adapter board, called ADP-GNSS, contains the u-blox GNSS module, the GNSS antenna 
connector and the USB connector for the GNSS module. 

The LENA-R8 and the GNSS adapter boards (ADP-R8 and ADP-GNSS respectively) are connected by 
male header board-to-board connectors on the bottom of the adapter boards and their corresponding 
female connectors on top of the lower board (EVB-WL3). 

The USB interface of the LENA-R8 cellular system is available on the native USB connector (J700) on 
the cellular adapter board (ADP-R8). 

The main UART and the auxiliary UART interfaces of the LENA-R8 cellular system can be routed as 
follows, by the 3-way UARTs

 routing switch (J601) available on the LENA-R8 adapter board (ADP-R8) 

as illustrated i

Figure 3

: 

 

EVB position (pin 1-2 of J601 shorted by jumper socket): main UART routed as 8-wire interface to 
the  lower  EVB-WL3  board  by  the  dual-in-line  male  board-to-board  connectors  mounted  on  the 
bottom of the adapter board ADP-R8. According to the mini-USB / DB9 switch (SW403) setting on 
the EVB-WL3, the main 8-wire UART interface can be accessed on the USB connector (J501) or 
on the RS232 DB9 connector (J500) on the EVB-WL3, with the on-board / B2B switch (SW401) on 
the EVB-

WL3 set to “on

-

board”. The 

auxiliary UART interface is not available. 

 

ADP position (pin 2-3 of J601 shorted by jumper socket): main UART and auxiliary UART routed 
as 4-wire interfaces to the USB two UARTs connector (J600) mounted on the adapter board, with 
the on-board / B2B switch (SW401) on the EVB-

WL3 board is set to “B2B”.
