1. Introduction
18 is based on originally imported RF chip CC2530 form TI in America. The IC chip is integrated with 8051
microcontroller and wireless transceiver inside, which is applicable to Zigbee design and 2.4GHz IEEE 802.15.4
protocol. All the IO ports are led out by the module, which means that multi-aspect development is realizable.

3. Pin definition
Power supply 2.0V ~ 3.6V DC
MCU GPIO/PA transmitting control the pin
MCU GPIO/PA receiving control the pin
MCU GPIO/PA receiving the high gain control the pin

4. Notes
Please try not to touch the electronic components with bare hands.
When welding, soldering iron needs grounding. The producer needs to
wear cable electrostatic bracelet which is grounding when mass
production.
Power quality has a great impact on the performance of the module,
please make sure the power supply has small ripple and avoid the
frequent and large jitter. π filter is recommended(Ceramic capacitor / /
tantalum capacitor + inductance).
Single-point grounding is recommended.
0 ohm resistor or 10mH inductance are recommended.
How to install antenna has a great impact on the performance of the
module, please make sure the antenna is exposed and vertical upward. It
will lead to the transmitting distance greatly weakened if the antenna
installs in the interior of housing.
FCC Statement
This device complies with part 15 of the FCC Rules. Operation is subject to the following two
conditions: (1) This device may not cause harmful interference, and (2) this device must accept any
interference received, including interference that may cause undesired operation.
Any Changes or modifications not expressly approved by the party responsible for compliance could
void the user's authority to operate the equipment.
The modular can be installed or integrated in mobile or fix devices only. This modular cannot be
installed in any portable device .
FCC Radiation Exposure Statement
This modular complies with FCC RF radiation exposure limits set forth for an uncontrolled environment.
This transmitter must not be co-located or operating in conjunction with any other antenna or
transmitter. This modular must be installed and operated with a minimum distance of 20 cm between
the radiator and user body.
If the FCC identification number is not visible when the module is installed inside another device, then
the outside of the device into which the module is installed must also display a label referring to the
enclosed module. This exterior label can use wording such as the following: “Contains Transmitter
Module FCC ID: 2ALPH-E18 Or Contains FCC ID: 2ALPH-E18”
When the module is installed inside another device, the user manual of the host must contain below
warning statements;
1. This device complies with Part 15 of the FCC Rules. Operation is subject to the following two
conditions:
(1) This device may not cause harmful interference.
(2) This device must accept any interference received, including interference that may cause undesired
operation.
2. Changes or modifications not expressly approved by the party responsible for compliance could void
the user's authority to operate the equipment.
The devices must be installed and used in strict accordance with the manufacturer's instructions as
described in the user documentation that comes with the product.
