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.
The block diagram of DKBLE is shown in the Figure 1. Please, refer to the latest data sheets for information
