1 Introduction
This manual provides a detailed reference for the JN5148 High-Power USB
Dongle, of type DR1131, supplied with JenNet-IP EK040 evaluation kit. The
dongle provides a platform for hardware development environment for wireless
microcontroller applications with a USB interface.
1.1 Features
The dongle has the following features:
JN5148-J01 device (mounted directly on the board)
Integrated PCB antenna
High-power capability
NXP LPC1343 USB interface and connector (interface chip is connected to
UART0 of the JN5148-J01 device)
Two LEDs (one red and one green)
This dongle is a high-power device with a radio transmission capability similar to
the high-power modules provided in the JenNet-IP EK040 evaluation kit.
1.2 Reference Design
A reference design (JN-RD-6034) for the JN5148 High-Power USB Dongle is
available from www.nxp.com/jennic/support. The reference design comprises a
ZIP file containing the following files:

2.3 LPC1343 Device
The LPC1343 device is connected to the USB connector and acts as an
interface between the PC and the JN5148 device. The LPC1343 will enumerate
on the PC as two devices:
1. A mass storage device used to program the Flash device for the JN5148
2. A virtual COM port connected directly to UART0 on the JN5148
2.4 JN5148 Device
The JN5148 circuit is based around the standard JN5148 reference design.
