Coming Soon… The M-Halowit Development Kit

The M-HaLowIt HDK (Halowit Development Kit) is made of the M-Halowit module in the XBee like form factors for embedded IoT designs. The HDK forms a complete demonstration and development platform for easily evaluation of the 802.11ah benefits. Delivered with sample software code, user guide and tutorials, the HDK can be considered as a reference design for device development as well the founding building block for your IoT device.
