The Boost 7 Click Board™ is based on the LT1945, a dual step-up and inverted DC/DC converter from Rohm Semiconductor that boosts an input voltage to a higher level required by an output load. The BD8316GWL switching regulator feature integrated N-channel FETs and power P-channel MOSFETs alongside a Soft Start feature. Each converter inside the LT1945 is designed with up to 200mA current limit generating well-regulated positive and negative outputs of ±3.3V or ±5V, making the BD8316GWL ideal for various portable applications.
As mentioned, the BD8316GWL can configure the positive and negative output voltage in the ±3.3V or ±5V range. The desired output voltage can be selected by positioning SMD jumpers labelled as V- SEL and V+ SEL to an appropriate position. It is also possible to control the activity of the output channels via two mikroBUS™ pins, SB1 and SB2 pins. These pins are routed to a default position of the AN and PWM pins of the mikroBUS™ socket. By setting these pins to a high logic state, we put the converter outputs to an active state, and regulated voltages are available at the output terminals. In the same way, setting these pins to a low logic level disables the channels.
The Boost 7 Click Board™ can operate with either 3.3V or 5V logic voltage levels selected via the VCC SEL jumper. This way, both 3.3V and 5V capable MCUs can use the communication lines properly. Additionally, there is a possibility for the BD8316GWL power supply selection via jumper labelled as VIN SEL to supply the BD8316GWL from an external power supply terminal in the range from 2.5V to 5.5V or with a selected voltage from mikroBUS™ power rails. However, the Click board™ comes equipped with a library containing easy-to-use functions and an example code that can be used, as a reference, for further development.

Additional Notes and Information
Depending on the development board you are using, you may need USB UART Click Board™, USB UART 2 Click or RS232 Click to connect to your PC, for development systems with no UART to USB interface available on the board. A UART terminal is available in all MikroE compilers.
The Boost 7 Click Board™ is supported with mikroSDK - MikroE Software Development Kit. To ensure proper operation of mikroSDK compliant Click board™ demo applications, mikroSDK should be downloaded from the LibStock and installed for the compiler you are using.
