AMBER WIRELESS AMB-DB2 Demonstration Board
Functional Description
The demonstration board AMB-DB2 allows for the establishment of a wireless
connection between wireless devices within a very short time. Moreover, the
AMB-DB2 board provides easy connection to a computer or to an external
processor. The EV kit is suitable for the commissioning of AMB2720, AMB2730,
AMBZ420, AMBZ430 and AMB2620. The radio module can be addressed directly from
the computer, using the Windows program
“AMBER Commander”.
The development board can be connected either directly to the USB interface of
a PC or to any other microcontroller system. For this purpose, there are
several pin headers to which all signals of the module are connected besides
of to the antenna connection.
Scope of Delivery
The AMB8425-M-EV kit is delivered in a product case and comprises:
- 2 x development board AMB-DB2 with mounted wireless module
- 2 x USB data cable 1.8m
The Demonstration Board
Overview
Power Supply
Power Adapter / Power Jack
The development board can be operated by connecting a 5 V power source to the
power jack.
If the power supply is connected and the bridge on P6 is set to “DC”, the
power LED will be active. It is also possible to supply the board via USB-
Interface. To do this, switch P6 to “USB”. Then the 5V of the USB-Interface is
used to supply the board. Power can also be supplied to the module via P7 pin2
(2.0 V – 3.6 V). However, in this case the USB converter will not be powered.
JP3 / Current Measurement
By default, P7 is closed for operation. If a current meter is connected
instead of the jumper, the power consumption of the radio module can be
measured here. If the meter is not attached and the bridge is not set, the
module will not receive any supply voltage. However, the power LED is active,
as it is connected upstream of the current measurement bridge in order not to
distort the module’s power consumption.
Interfaces
UART / USB
The UART of the module can be connected to the USB converter by setting the
jumper on P8 and P9 to UART and the jumper on P10 (Pin 13-14 and Pin 15-16).
In this case, the module can be connected directly to a PC via USB cable. If
the FTDI-driver is used, the PC will show you a virtual COM-Port to
communicate with the module.
UART / TTL
If a microcontroller is to be connected to the module, remove the jumper on
P10. The UART can be accessed directly on the pin bar to which all other pins
of the module are connected.
Watch the level compatibility. When powered over the power jack or USB (section 3.2.1), the levels of the module are 3.3 V. If the power supply is provided by P7 pin 2 (section 3.2.1), the levels of the module can be adjusted in the range from 2.0 to 3.6 V.
Reset
On the development board, there is a “RESET” button by means of which the module can be reset. Moreover, the reset is available on pin 27.
