1 Design Overview
BLE Development Kit, DKBLE, is targeted for engineers evaluating Bluetooth Smart modules BLE112,
BLE113 and BLE121LR. DKBLE is platform containing various switchable peripherals for creating and testing
several different applications utilizing Bluegiga Bluetooth Smart modules. The modules are assembled on a
carriers boards and DKBLE contains a header type of interface for plugging in the module carriers. Thus each
module can be tested and compared with each other on the same platform. DKBLE contains:

On-Board debugger

Switchable powering either from a coin cell battery or USB

UART interface through USB to UART converter

USB interface

programming interface for upgrading the firmware and parameters

Display connected to SPI

Accelerometer connected to SPI

Altimeter connected to I2C

Potentiometer for ADC input

Push buttons for 3 PIOs and reset

All the signals available at test points

Current measurement points for measuring peak currents of the module, DC current of the
module and DC current of the whole board.
