PCIe MiniCard Half Size – 3G Only

GTM671W and GTM679W

GTM661W and GTM669W

By adding a WiFi component on the half-size 3G PCIe minicard, only one PCIe Minicard slot is needed, hence lowering overall device cost. This single slot can be equipped with a standard WiFi module for the basic device configuration or with the GTM671/679 combo module when both WiFi and 3G connectivity are desired for the device. Option's half-size PCIe module is developed specifically for integration in compact devices such as netbooks, tablet PCs, routers or security cameras where space is limited but a standard connector-based integration is still preferred over an LGA component that needs to be soldered on the base board.
