VCC: Supply voltage of 1.9-3.6V (other pins can tolerate 5V)
GND: Ground
CE: Chip Enable - sets module to receive or transmit mode
CSN: Chip Select Not - an active-LOW pin and is normally kept HIGH. When this pin goes low, the module begins listening on its SPI port for data and processes it accordingly.
IRQ: Interrupt pin - can optionally alert when new data is available to process
SCK: Serial Clock for SPI
MOSI: Master Out Slave In for SPI input to module
MISO: Master In Slave Out for SPI output from module
Unlimited Blocks, Tabs or Accordions with any HTML content can be assigned to any individual product or to certain groups of products, like entire categories, brands, products with specific options, attributes, price range, etc. You can indicate any criteria via the advanced product assignment mechanism and only those products matching your criteria will display the modules.
Also, any module can be selectively activated per device (desktop/tablet/phone), customer login status and other criteria. Imagine the possibilities.
