Sentilla Confidential Chapter 1 1• • • ••• Chapter 1• • • • • • IntroductionThe SENARM01 serves as a building block for other products. This document provides you with a description of its operation, basic specifications, safety instructions, and regulatory information. Theory of OperationSENARM01 is a data acquisition, processing, and communication chip. It is designed to acquire data from a variety of sensors, process that data, and participate in a multihop wireless network. The device uses IEEE 802.15.4 standard for wireless communication. Physical CharacteristicsThe module is packaged in an LCC68 form factor. The package pins bring out analog input signals, digital input and output, and RF interface. The package is physically shielded. The device buffers all input signals; it sources (or sinks) a maximum of 25mA across all output pins.Communication CharacteristicsIn normal operation, the OEM Module complies with this protocol to implement various layers of the protocol stack:•Physical — 802.15.4 PHY - 250 kbps signal in 128 byte packets are encoded using DSSS. The sequence of chips is modulated using O-QPSK and transmitted in a 2.4 GHz band.

Only use “No-Clean” solder paste. Do not clean or wash the printed circuit board (PCB) after soldering. When you use “No-Clean” solder paste, cleaning is not necessary. For the best connection to the PCB, the solder connection should fill the edge-plated via hole almost to the top.

CAUTION: The user is not permitted to make any modifications to this equipment without express approval from Sentilla Inc. Doing so will void the user’s authority to operate this equipment. This equipment has been tested and found to comply with part 15 of the FCC Rules. Operation is subject to the following two conditions:1This device may not cause harmful interference, and 2This devices must accept any interference received, including interference that may cause undesired operation. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed in accordance with the instructions, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference in which case the user will be required to correct the interference at his own expense. However, there is no guarantee that interference will not occur in a particular installation.
10 Chapter 4 Sentilla Confidential• • • •••SENARM01 Sentilla OEM Module User’s GuideFCC RF Radiation Exposure StatementTo comply with the FCC and ANSI C95.1 RF exposure limits, the antenna(s) for this device must:•The antenna must operate with a separation distance of at least 20 cm from all persons using this equipment. •This transmitter must not be co-located or operating in conjunction with any other antenna or radio transmitter. •Installers and end users must follow the installation instructions provided by the manufacturer.•End users must be provided with specific operations for satisfying RF exposure compliance.Antenna ListThis device has been designed to operate with the antennas listed below, and having a maximum gain of 3.3 dB. Antennas not included in this list or having a gain greater than 3.3 dB are strictly prohibited for use with this device. The required antenna impedance is 50 Ohm1Texas Instruments DN0007, maximum gain of 3.3 dB2HyperLink Technologies HG2402RD-RSF, maximum gain of 2.2 dB
