HumPROTM Series Frequency Hopping

Digital Data Transceiver Module

At below $9 in volume, the Hummingbird platform is the lowest cost complete

wideband transceiver with microcontroller module on the market today. The

HumPROTM is built on this platform and is designed for robust data transfer. It

includes a frequency hopping protocol and supports versions at 2.4GHz and

900MHz with a common footprint and pin out.

Low Cost: Linx designed the Hummingbird platform with cost in mind from the

start to appeal to OEMs who have a limited budget to incorporate RF. It uses

advanced system on chip (SoC) technology to minimize the footprint and the

number of components. The module is designed for high volume production,

leading to a price that is nearly half that of similar modules, and making it cost

competitive with discrete designs.

Robust: Built-in error detection and retransmission options create extremely robust

point-to-point links for bi-directional data transmissions.

Frequency Hopping: The module has a FHSS protocol that typically locks in

under 50ms. This allows it to quickly wake up, send data and go back to sleep,

saving power consumption in battery-powered applications that have strict power

budgets. It handles all protocol functions automatically.

Ease of Implementation: The user can configure a wide variety of settings through

a standard UART interface. For point-point applications, the modules can be

configured once, then send and receive data without need for further commands.

For larger networks, commands support selective addressing and group

broadcasting. The simple interface significantly reduces firmware development.

Addressing: All HumPROTM modules have a unique 32-bit serial number that can

be used as an address. Multiple addressing modes gives the options for 16 or

32 bit source and destination addressing, enabling point-to-point and broadcast

messages. Address masking by the receiving module allows for creating subnets.

Advanced networks can be implemented with an external microcontroller.

Small Size: Like its namesake, Hummingbird modules are tiny. At 11.5mm by

14.0mm, it is less than one quarter the size of similar competitive modules.

Low Power: Linx designed the Hummingbird platform for battery powered

applications. It operates as low as 2.0 volts and has low transmit current of 28 to

36mA, receive current of 25mA and standby current of under 1µA.

Ample Range: The HumPROTM 900MHz version outputs up to 10dBm, resulting

in a line-of-sight range of up to 1,600m (1.0 miles), depending on the antenna

implementation. The 2.4GHz version outputs up to 1dBm, resulting in a line-of-sight

range of 100m (300 feet).

External Amplifiers: The module has control lines that allow it to work with an

external PA and LNA for applications that need more system range.

Certification: The HumPROTM Series is available in a non-certified version and in

pre-certified versions with an RF connector or antenna.
