Input
I
C clock. It is connected to the I2C_CLK pin
of the module via low-voltage level translators.
For details, refer to ZigBit datasheet [1].
2
Bidirectional
I
C data. It is connected to the I2C_DATA pin
of the module via low-voltage level translators.
For details, refer to ZigBit datasheet [1].
Output
Output of internal voltage regulator. Normally,
the voltage is 3.6 V.
Output
ZigBit supply voltage
Input
Reset Pin. Active low. This pin is connected in
parallel to the RESET button on the board.
Output
This is Transmit Data Pin for USART0
interface of the ZigBit module. It is connected
directly to the USART0_TXD pin of the module.
Digital logic level. For details, refer to ZigBit
datasheet [1]. [1]
Input
This is Receive Data Pin for USART0
interface of the ZigBit module. It is connected
directly to the USART0_RXD pin of the module.
Digital logic level. For details, refer to ZigBit
datasheet [1].
