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.

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)
