1. INTRODUCTION

The Jorjin WS2119-A0 is Bluetooth®Low Energy and Sub-1GHz dual band module. The

WS2119E20A is the development kit for WS2119-A0. The WS2119E20A provides a set

of hardware resources for RF signal evaluation of both BLE and Sub-1GHz and

development platform. It also provides a set of hardware resources for a wide range

of application scenarios: sensor data (accelerometer, pressure and temperature

sensor, needs additional sensor board), remote control (buttons and LEDs) and

debug message management through USB virtual COM. Three power options are

available (USB only, battery only and external power supply plus USB) for high

application development and testing flexibility.

board is being powered, either via:

micro USB connector J4 (Figure 2: WS2119E20 board components" –region D)

batteries(region L)

an external DC power supply plus micro USB connector

The following table describes the power supply modes available on the WS2119E20

board and corresponding jumper settings.

3.6. Push-buttons

The board has one user button to reset the microcontroller (Figure 2: " WS2119E20

board components" –region H) and one further button for application purposes

(region I).

3.7. JTAG connector

A JTAG connector (Figure 2: " WS2119E20 board components" –region G) allows

BlueNRG-1 microcontroller programming and debugging with an in-circuit

debugger and programmer such as ST-LINK/V2.

Only SWD mode is supported.

3.8. LEDs

LEDs CR1 (green, power LED) and CR2 (red) are available on the board (Figure 2:

"WS2119E20 board components" –regions J and K).

3.9. STM32L151CBU6 microcontroller

The most important feature of the STM32L151CBU6 48-pin microcontroller (Figure 2:

"WS2119E20 board components" –regions M) is the USB to serial bridge providing an

I/O channel with the BlueNRG-1 device.

The microcontroller is connected to the BlueNRG-1 device through an ST2378E level

translator (region O).

The STM32L microcontroller on the board is not intended to be programmed by users.

ST provides a pre-programmed firmware image for the sole purpose of interfacing

BlueNRG-1 to a USB host device (e.g., a PC). The JTAG connector (Figure 2:

"WS2119E20 board components" –regions N) is only for Jorjin internal used.

3.10. Hardware setup

1. Connect one 2.4GHz antenna to BLE U.FL connector (Figure 2: "WS2119E20 board

components" –regions B), Connect one 915MHz antenna to Sub-1GHz U.FL

connector (regions C)

2. Configure the board to USB power supply mode as per the jumper settings in

Table 3: “WS2119E20 kit platform power supply modes”

3. Connect the board to a PC via USB cable (connector J4)

4. Verify the power indication LED CR1 is on.
