Laird’s Development Kit (DVK-BT860-Sx)
provides a platform for rapid prototyping of BT860 series modules. The
development board provides simple, easy to use access to the various hardware interfaces and configuration
options for the module. The DVK is the perfect platform to provide for early development testing of the BT860
module series features and functionality, prior to designing the module onto a host PCB.
This manual is for the development PCB which is DVK-BT860 1.0 on PCB.

Main Development Board
The development board allows the BT860 module to be easily connected to a PC. The development board
provides USB to UART converter linking to USB connector and the BT860 UART HCI interface. Any Windows PC
(Windows 7 or later) auto-installs the necessary drivers and if your PC can not locate the drivers, you can
download them from

Power supply options for powering development board from:
▪
▪
USB
External DC supply
The DVK-BT860-Sx includes a USB cable to provide power to the development board. This should be plugged
into a PC USB port, a USB hub, or a mains adaptor with a USB output. If a hub is used, it should be a powered
USB hub to ensure that sufficient current is available at the port. The BT860-Sx module can be driven by the
available current at a USB port
.
The low noise LDO (U7) on the DVK-BT860-Sx provides the 3.3V out to support the whole board’s operating
voltage.
