APEX LT PRODUCT SUMMARY
Product Description
The LS Research APEX LT module is a 2.4 GHz transceiver providing a solution for data
links and wireless networks. The module is based on the Ember EM260 network processor
links and wireless networks. The module is based on the Ember EM260 network processor
providing an IEEE 802.15.4 radio transceiver with a SPI base interface. The SPI interface
gives the flexibility to choose the external microprocessor to best fit the application.
