Specifications
2.11 Audio input/output connectors (J1401/P1401/J1402 & J1403)
The Audio CODEC used on the i.MX 6UltraLite EVK board is Wolfson’s Low Power, high quality Stereo
Codec, WM8960. The digital interface between i.MX 6UltraLite and WM8960 includes four signals:
• SYNC_CLK
• BCLK
• DACDAT
• ADCDAT
i.MX 6UltraLite also provides the MCLK to WM8960.
i.MX 6UltraLite EVK includes one headphone interface (J1401), one onboard MIC (P1401), and two
speaker interfaces (J1402, J1403). J1401 is a 3.5mm 4-pole (or TRRS) phone jack, which supports jack
detect.
2.12 USB debug connector (J1901)
On the EVK board, CP2102, a USB to Serial UART IC is used to convert the UART signal to the USB
signal. With the Micro-B USB connector J1901, the connection for debugging is simplified. A Micro-B to
standard A USB cable is enough.
UART1 port is used as the default debug port. No RTS or CTS signals are sent from the processor to the
debug connector because these signals are commonly ignored by most applications. The required terminal
settings are shown in the following table.
2.13 Bluetooth Connector (J1701)
On the EVK board, the J1701 is connected to i.MX 6UltraLite UART2 port, and can be used for Bluetooth.
Silex Bluetooth module SX-SDCAN-2830BT is recommended. The developer may need to consult Silex
for the detailed information of the module. If the developer wants to verify other Bluetooth modules, a
convert board might be needed.
NOTE
J1701 is a bottom-contact type connector for BT connection on the Rev. C
board. 20PIN/0.5mm pitch same side FFC/FPC should be used to connect
with Silex Bluetooth module SX-SDCAN-2830BT, as shown in the
following figure.
