==Block Diagram==
The following picture shows Bora-EVB BoraEVB block diagram:
[[File:Boraevb-bd.png|thumb|center|600px|BoraEVB block diagram]]
== Features ==
* 10/100/1000 Ethernet#0 (PS)* 10/100/1000 Ethernet #1 (Routed through EMIO)* 1x USB 2.0 OTG(MicroAB connector)* 1x Serial port (RS232DB9)
* 1x MicroSD
* External DDR3 SDRAM bank
* XADC
** Some signals of Bank 35 can be configured as XADC signals. For this reason they can be routed alternatively to 2.54mm-pitch connectors, instead of DDR3 memory.
* JTAG port
* Trace port
* Socket for [[Wireless_Module_(DWM) | DWM Wireless Module]]
* Digilent Pmod™ Compatible expansion connectors
* Headers for external for NAND flash and SPI NOR flash
* 2.54mm-pitch pin-strip connectors for Bora PS and PL configurable peripherals (MIO and EMIO interfaces, GPIOs, custom IPs, ..)
* Jumpers for voltage selection of the PL banks
* +12V power connector
== Known limitations ==
Board version CS040713A has the following limitations:

!Issue
!Description
|-
| ETH0 interface
| Mistake in the connection of the center tap pins. They should be separated from one another and connected through separate 0.1μF common-mode capacitors to ground (for further details (eg: connection and selection of the magnetics), please refer to the Micrel KSZ9031RNX datasheet).
|-
|External DDR3 bank
|The DDR3 SDRAM bank is not supported in BELK 2.0.0
|-
|ETH1 interface
|The additional Gigabit Ethernet interface (ETH1) is not supported in BELK 2.0.0

=== POWER GOOD signals selector - J10 ===
J10 is a 8-pin 4x2x2.54 pitch vertical headerused for the selection - through jumpers - of the POWER GOOD options. The following table reports the pinout of the connector:

=== BANK35, BANK13 VDDIO selector - J11 ===
J11 is a 8-pin 4x2x2.54 pitch vertical headerused for the selection - through jumpers - of the bank supply voltages. The following table reports the pinout of the connector:
{| class="wikitable"
The available configurations are:
# Jumper on 1-2 -> supply VDDIO_BANK35 with 3.3V('''requirerd when EVBB DDR3 device is used''')# Jumper on 3-4 -> ('''Not Available''') supply VDDIO_BANK35 with EVB_VDDQ_1V5 ('''requirerd when EVBB DDR3 device is used''')
# Jumper on 5-6 -> supply VDDIO_BANK13 with 3.3V
# Jumper on 7-8 -> supply VDDIO_BANK35 with EVB_VDDIO_BANK13 ('''requirerd when TRACE is used''')
The following rules must be observed:
* Because of a hardware limitation, VDDIO_BANK35 '''must be configured for 3.3V power supply (Jumper on 1-2)'''.
* The configuration 1. (Jumper on 1-2) excludes 2. (Jumper on 3-4) (and viceversa)
* The configuration 3. (Jumper on 5-6) excludes 4. (Jumper on 7-8) (and viceversa)
The DEFAULT configuration is:
* Jumper on 31-4 2 ('''please note that this jumper must not be removed''')
* Jumper on 5-6
=== Touch screen - J25===
J25 is a ZIF 4-pin 1.0mm pitch connector that connects the touchscreen drive lines to the touch screen controller on the EVBBoraEVB. The following table reports the pinout of the connector:
