Hardware description

The following sections describe the components of the kits.

2.1

STEVAL-IDB005V1 motherboard

The motherboard included in the development kit allows testing of the functionality of the

BlueNRG-MS processor. The board can be used as a simple interface between the

BlueNRG-MS and a GUI application on the PC. The STM32L microcontroller on the board

can also be programmed, so the board can be used to develop applications using the

BlueNRG-MS. A connector on the motherboard (Figure 1) allows access to the JTAG

interface for programming and debugging. The board can be powered through a mini-USB

connector that can also be used for I/O interaction with a USB Host. The board includes

sensors, and buttons and a joystick for user interaction. The RF daughterboard can be

easily connected through a dedicated interface.

This is a list of some of the features that are available on the boards:

•

STM32L151RBT6 64-pin microcontroller

•

Mini USB connector for power supply and I/O

•

JTAG connector

•

RF daughterboard interface

•

One RESET button and one USER button

•

One LIS3DH accelerometer

•

One STLM75 temperature sensor

•

One joystick

•

5 LEDs

•

One PWR LED

•

One battery holder for 2 AAA batteries

•

One row of test points on the interface to the RF daughterboard
