BT-11 Datasheet
Product Specification
15mm x 27mm
Description
With class 1 power of up to +17dBm, the BT11 module has one of the best ranges in the industry.
The BT11M/L module includes 16 general purpose input/output lines, several serial interface options, analog-to-digital inputs, and up to 2M bps data throughput.
The BT11M/L 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.

6 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.
6.1 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.
6.2 Module Reflow Installation
The BT-11M/L 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.
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.
6.3 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 100K Ω (nominal) resistors GPIO [8] to GPIO [15] are internally pulled up with 100KΩ
(nominal) resistors.
6.4 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.
