Description
The added class 1 power, +16dBm, of the BT-11, gives this module one of
the best ranges in the industry. It’s completely pin compatible with the lower
power BT-21, and offers a second power choice on the same design.
The BT-11 module includes 16 general purpose input/output lines, several
serial interface options, analog-to-digital inputs, and up to 2M bps data
throughput.
The BT-11 is a surface mount PCB module that provides fully embedded,
ready to use Bluetooth wireless technology. The reprogrammable flash
memory contains embedded firmware for serial cable replacement using the
Bluetooth SPP profile. Other popular Bluetooth profiles, such as OBEX, are
also available.
Customized firmware for peripheral device interaction, power optimization,
security, and other proprietary features may be supported and can be
ordered pre-loaded and configured.

Hardware Design
Amp’ed RF modules support UART, USB, SPI, I2C and GPIO hardware interfaces. Note that the usage of
these interfaces is dependant upon the firmware that is loaded into the module, and is beyond the scope
of this document.
Notes
All unused pins should be left floating; do not ground.
All GND pins must be well grounded.
The area around the module should be free of any ground planes, power planes, trace routings, or
metal for 8 mm from the antenna in all directions.
Traces should not be routed underneath the module.

Module Reflow Installation
The BT-11 is a surface mount Bluetooth module supplied on a 24 pin, 6-layer PCB. The final assembly
recommended reflow profiles are:
For non Pb-free applications, Sn63Pb37 solder is recommended.
ƒ

Maximum peak temperature of 208° - 210°C (below 220°C).
Maximum rise and fall slope after liquidous of < 2°C/second.
Maximum rise and fall slope after liquidous of < 2°C/second.
Maximum time at liquidous of 50 – 90 seconds.
For RoHS/Pb-free applications, Sn96.5/Ag3.0/Cu0.5 solder is recommended.

Maximum peak temperature of 230° - 240°C (below 250°C).
Maximum rise and fall slope after liquidous of < 2°C/second.
Maximum rise and fall slope after liquidous of < 3°C/second.
Maximum time at liquidous of 40 – 80 seconds.

GPIO Interface
All GPIOs are capable of sinking and sourcing 8mA of I/O current. GPIO [0] to GPIO [7] are internally
pulled down with 100KΩ (nominal) resistors GPIO [8] to GPIO [15] are internally pulled up with 100KΩ
(nominal) resistors.
UART Interface
The UART is compatible with the 16550 industry standard. Four signals are provided with the UART
interface. The TXD and RXD pins are used for data while the CTS and RTS pins are used for flow
control.

FCC Regulatory Compliance
This module has been tested and found to comply with the FCC Part15 Rules. These limits are designed to
provide reasonable protection against harmful interference in approved installations. This equipment
generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance the
instructions, may cause harmful interference to radio communications. However, there is no guarantee that
interference will not occur in a particular installation. 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.
Modifications or changes to this equipment not expressly approved by Amp’ed RF may void the user’s
authority to operate this equipment.
Modular Approval
FCC ID: WDTBTMOD1
In accordance with FCC Part 15, the BT-11 is listed above as a Modular Transmitter device.
FCC Label Instructions
The outside of final products that contain a BT-11 device must display a label referring to the enclosed
module. This exterior label can use wording such as the following: “Contains Transmitter Module FCC ID:
WDTBTMOD2 or “Contains FCC ID: WDTBTMOD1. Any similar wording that expresses the same meaning
may be used.
