Jumper
Description
J1
Test points for S2-LP GPIO0 – GPIO3
J3
UART TX of BlueNRG-1 is connected (Fitted) or disconnected (Not fitted) to STM32.
J5
UART RX of BlueNRG-1 is connected (Fitted) or disconnected (Not fitted) to STM32.
J8
pin 1 and 2 UART RX and TX of MCU
pin 3 GND
J10
DIO6 of BlueNRG-1 is connected (Fitted) or disconnected (Not fitted) to EEPROM_CS pin.
J11
Fitted: to provide VBLUE to BlueNRG-1. It can be used also for current measurement.
J12
This jumper is no function in WS2118E00.
J13
Fitted: to provide VBLUE to S2LP. It can be used also for current measurement.
3.5. Extension connectors
WS2118-00 module signal test points are shared on two Arduino-compliant
connector rows: CN1, CN3 (Figure 2: " WS2118E00 board components" – region E)
and CN2, CN4 (region F). See Table 2: "WS2118-00 module pin description with board
functions".
You can also install some sensor module board in the WS2118E00 kit platform
through these extension connectors. Please contact Jorjin to get more information.
