Hardware design
The SPBT2632C1A module without AT2 command embedded FW, supports UART, SPI, I
and GPIO hardware interfaces. Note that the use of these interfaces is dependant upon the
firmware that is loaded into the module, and is beyond the scope of this document. The AT2
command interface uses the main UART by default.
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 6 mm from the antenna in all directions.
Traces should not be routed underneath the module.
Module reflow installation
The SPB2632C1A is a surface mount Bluetooth module supplied on a 24-pin, 6-layer PCB.
The final assembly recommended reflow profiles are indicated here below.
The soldering phase must be executed with care: In order to avoid undesired melting
phenomenon, particular attention must be paid to the set-up of the peak temperature.
