Instructions to connect the SPI interface to the SG909-0034
(SPI 3.3V)
1. Connect a +3.0 to 3.6V (min 200mA) supply to JP1 pin 2. This is required to power the WLAN
2. Connect the SPI Clock to JP1 pin 3
3. Connect the SPI Master out, Slave in (MOSI) to JP1 pin 4
4. Connect the SPI Master in, Slave out (MISO) to JP1 pin 5
5. Connect the SPI Chip Select to JP1 pin 6
6. Connect the power up control to JP1 pin 8. This pin is normally pulled to approximately 2V upon
7. Connect the SPI Interrupt Request (IRQ) to JP1 pin 11
8. Connect the 3.0 to 3.6V supply to JP1 pin 14. This is optional. The WLAN Module has a pull up
9. Pins 7, 9, 10, 13, 15 and 16 are the ground returns for SPI signals and the external power supply.
10. JP1 pin 1 is “no connect”
module Transmit Power Amplifier, voltage regulators, low frequency clock oscillator and TX
controls.
application of the 3V to 3.6V supply, powering the WLAN module on. It is used to power down the
WLAN when grounded.
resistor for enabling SPI operation. This pin selects the SPI/SDIO mode of operation for all
Sagrad modules with the exception of SG901-1030 Wi-Fi module where it becomes the antenna
diversity control.
