6.4 Mini USB
This connector can be used to program the board (as an alternative to using a programmer tool).
Make sure to enter bootloader mode and use the mini USB to establish connection between the
board and the personal computer. To enter BSL mode hold USB_BSL and power the board. Or
while the board is powered hold USB_BSL down then press RESET and then release USB_BSL. If
the board is started in BSL mode the green LED should remain off.
There are no drivers required. This is because the MSP430 reports itself as a Human Interface
Device (HID), which has built-in Windows support. HID is a great fit for firmware updates. The
only way to upload code via the USB at the moment is to use a pack of softawre tools from the
official Texas Instruments web-site. The software tool to search for and download is named:
“MSP430 USB Firmware Upgrade Example”.
Note that you can compile binaries (suitable to upload via the bootloader) using various software
products. People typically use Code Composer Studio; IAR Embedded Workbench for MSP430;
Rowley CrossWorks for MSP430.

6.5 Battery connector
Please make sure you use 3.7V lithium battery. The voltage of such a battery might vary from 2.75V
up to 4.2V (discharged, fully charged).
Note that the board features battery charging circuit. It will charge the battery if it's voltage drop
below a certain threshold and other source of power is present. Mind that such a charging might
draw considerable amount of current (especially if the battery is fully discharged). When the board
has a battery connected AND USB connected simultaneously the battery would get recharged
thanks to the recharge circuit.
