1. Introduction
The ZTM-W / ZTM-P is a FCC certified design and a small-sized wireless-UART converter solution
consisting of a micro controller unit with RF transceiver and a RF power amplifier front-end, or often
called the low-noise amplifier (LNA), and it offers excellent the sensitivity. The ZTM-W / ZTM-P is
based on the 2.4 GHz IEEE 802.15.4 standard, and either the function of radio-frequency or ZigBee
firmware is available to be used. It can be controlled through an external host/system microcontroller
or external evaluation software through the UART interface. We use the same hardware but the
different firmware to achieve the RF Modem, ZigBee Coordinator or ZigBee Router.
