The carrier card was designed by iWave to meet the network Router requirement using iWave’s i.MX6 Qseven SOM. The Wi-Fi modules and GPRS modules (mini PCIe form factor) were interfaced to the PCIe 2.0. With the Gigabit Switch connector, the board supports four RJ45 connectors. Totally, there are six Mini PCIe slots available, accommodating both PCIe and USB signals. Microcontroller, in the carrier card, monitors parameters like voltage levels and power status. It also provides user interface by controlling appropriate LED’s to indicate which mini PCIe module is active.
iWave’s i.MX 6 Qseven SOM is connected to the PIC Microcontroller through I2C. Connection is in such a way that iMX6 processor, as a Master and PIC microcontroller, as a Slave. Master and Slave to communicate effectively, iWave has designed a unique customized Communication Protocol in which master (iMX 6) will control the peripherals connected to slave (PIC) through protocol commands. iWave also implemented a software in our Qseven module that enables the upgrade of the microcontroller firmware.
