1. Introduction
The HPBU01-TR-915 is a compact, low power, bidirectional transceiver module in the
915 MHz range utilizing Sub-GHz technology. The module provides long range and high
output power while also reducing current consumption to a minimum. The HPBU01-TR-
915 also utilizes the widely used ATmega328P processor. The coupling of Sub-GHz
transceiver technology and ATmega328P processor allows for faster prototyping and
fast time to market. The HPBU01-TR-915 module utilizes a patch antenna to reduce the
need for RF development and antenna tuning and provide consistent range
expectations.

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.
This equipment has been tested and found to comply with the limits for a Class B digital
device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference in a residential installation. This
equipment generate, uses and can radiate radio frequency energy and, if not installed
and used in accordance with the instructions, may cause harmful interference to radio
communications. However, there is no guarantee that interference will not occur in a
particular installation.
If this equipment does cause harmful interference to radio or television reception, which
can be determined by turning the equipment off and on, the user is encouraged to try to
correct the interference by one or more of the following measures:
-- Reorient or relocate the receiving antenna.
-- Increase the separation between the equipment and receiver.
-- Connect the equipment into an outlet on a circuit different from that to which the
receiver is connected.
-- Consult the dealer or an experienced radio/TV technician for help.
To maintain compliance with FCC’s RF Exposure guidelines, this equipment should be
installed and operated with minimum distance between 20cm the radiator your body:
Use only the supplied antenna.
