2.4 GHz starter kit

Jennic has released a low-cost starter kit allowing developers with little or no wireless experience to develop products.

The JN5139-EK020 IEEE 802.15.4/JenNet kit simplifies the evaluation and application development of low-power wireless connectivity products using the company’s JenNet networking stack.

The kit provides the flexibility to develop wireless capability by using Jennic JN5139 microcontrollers and modules as wireless processors or coprocessors.

In the single chip configuration, the kit demonstrates the protocol and application both running on the JN5139 32-bit wireless microcontroller. The Jenie C-based API provides communication between the application and the wireless connectivity protocol.

The kit comprises three nodes, preprogrammed with a range of example applications to demonstrate the capabilities of wireless sensor networks.

The kit demonstrates point-to-point connections and a simple network using a coordinator, router and endpoint.

Wireless co-processor operation is demonstrated using a PC connection to the nodes and communication via At-Jenie serial commands. RF performance, range and packet error rate monitoring are also included, allowing users to evaluate the radio performance of the JN5139 modules and 2.4 GHz IEEE 802.15.4 standard.

Each node includes a standard Jennic module, which integrates a JN5139 wireless microcontroller and an antenna. Operating at 2.4 GHz, the modules have worldwide RF approval.
