SnowBall board Specification

5.18. Power Connectors
Power will be supplied via the USB OTG connector and if a need arises for additional power, such as
when a board is added to the expansion connectors, a larger 5V wall supply can be plugged into the
+5V DC power jack. When the wall supply is plugged in, it will remove the power path from the USB
OTG connector and will be the power source for the whole board. The power supply is not provided
with the Snowball board.
When using the USB OTG port in the host mode, the +5V DC supply must be connected as the USB
port will be used to provide limited power to the hub at a maximum of 100mA, so the hub must be
powered. The 200mA is not impacted by having a higher amperage supply plugged into the DC power
jack. The 200mA is a function of the OTG port itself. Make sure the DC supply is regulated and is
a clean supply.
Warning
The Snowball board can only be supplied by a +5V external power supply.
5.19. JTAG Connector
A 20 pin JTAG header is provided on the Snowball board to facilitate the SW development and
debugging of the board by using various JTAG emulators. The interface is at 1.8V on all signals. Only
1.8V levels are supported.
Warning
DO NOT expose the JTAG header to 3.3V
5.20. MIPI Debug Connector
A 34 pin connector is provided on the Snowball board to facilitate the SW development and debugging
of the board by using various MIPI Debug Tools. This connector is only mounted on the SDK version.
5.21. RS232
The RS232 interface is provided either on a HE10-2x5 header or on a mini-b USB connector. These
two connectors are only available on the PDK version. The user can choose to use either of them
by placing or removing a jumper on a 2 pin header. Regarding the SDK version, the RS232 is only
available on the mini-b USB connector. The HE10-2x5 header requires an IDC to DB9 flat cable,
which is not provided, to access the serial port.
5.22. Expansion connector
There is one 2.54mm pitch 1x16 pin header available on the two versions of the Snowball board. It
provides several buses like I2C, UART and several GPIOs for prototyping. On the PDK version only,
there are two fine pitch connectors:
• A 60 pin expansion connector located on the top side
• A 120 pin expansion connector located on the bottom side
The pinout of these expansion connections can be found later in this document.
