SU60-SIPT module. This allows you to test different operating scenarios. The development board allows the SU60-SIPT module to physically connect to a SDIO host via the supplied SDIO extension cable and USB host via USB cable for development purposes. The development board also provides USB-to-Virtual COM port conversion through a FTDI chip – part number FT232R.
User Guide – Pin header (Ammeter) IO break-out (2.54 mm pitch headers) connectors interface for plugging-in external modules and accessing all interfaces of the SU60-SIPT • module [UART, LTE coexistence, PCM, GPIO, JTAG]. Two buttons and LEDs for user interaction •...
Figure 1: Development board 3 Functional Blocks The development board is formed from the following major functional blocks: Pin Definitions 3.1.1 SDIO-Pin Header Figure 2: DVK-SU60-SIPT SDIO pin header Table 1: SDIO pin definitions Voltage Name Type Description If Not Used Ref.
USB1 / USB2 SDIO Interface Figure 3: DVK-SU60-SIPT power supply The development board can be powered from DC 12V supply (into DC jack connector CN1), USB (type micro-B) connector (USB1 and USB2), or the host interface (PCIe or SDIO interface). The power source fed into DC jack is regulated down to 5V with an on-board regulator and wire to SW1.
The 5V from the USB or the DC jack is regulated down to 3.3V with an on-board regulator on the development board. Switch SW1 selects between the regulated 5V and USB. The voltage from host interface (PCIe or SDIO interface) is not regulated but is fed directly to SU60-SIPT module supply pin.
3.5 4-wire UART Serial Interface The development board provides access to the SU60-SIPT module 4-wire UART interface (TX, RX, CTS, RTS) either through USB (via U7 FTDI USB- UART convertor chip) or through a breakout header connector J15, J16, J17, and J18. Refer to...
Figure 6: USB to UART Interface and Header to UART interface 3.6 32.768KHz Oscillator The development kit is fitted with a (U5) 32.768KHz oscillator which provides sleep clock to SU60-SIPT module. Fit a jumper on J14 to disable the sleep clock, if necessary.
