3.4. Other jumpers

The following jumpers are available:
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 Fitted: to provide VBLUE to RFX1010. It can be used also for current measurement.
J13 Fitted: to provide VBLUE to S2-LP. It can be used also for current measurement.

3.5. Extension connectors

WS2119-A0 module signal test points are shared on two Arduino-compliant
connector rows: CN1, CN3 (Figure 2: " WS2119E20 board components" – region E)
and CN2, CN4 (region F). See Table 2: "WS2119-A0 module pin description with
board functions".
You can also install some sensor module board in the WS2119E20 kit platform
through these extension connectors. Please contact Jorjin to get more information.
