3.2.1. A2541 Radio Module (U2)
The Anaren A2541 module is a 2.4GHz Bluetooth low energy compliant radio preloaded with
Em-Ware from Emmoco (based on the Texas Instruments BLE-STACK). For details regarding
the radio module, refer to the A2541E24x and A2541R24x User’s Manuals located on the
Anaren website (www.anaren.com/air). For details regarding Em-Ware, refer to the Emmoco
Em-Ware Wiki (see section 2.2).
3.2.2. USB-UART (U3)
The FTDI FT234XD USB to Basic UART device provides virtual COM port (VCP) access to the
radio module. Please refer to the FT234XD datasheet on the FTDI website (www.ftdichip.com)
for further info regarding this device.
3.2.3. Current Sense Amplifier (U4)
The Texas Instruments INA216A2 provides a method for monitoring current in near real-time
using an oscilloscope. The device amplifies the voltage across shunt resistor R23 with a gain of
50 and provides a single-ended analog output referenced to GND. This circuit is not calibrated
and should not be used for taking accurate measurements. Please refer to the INA216A2
datasheet on the TI website (www.ti.com) for further info regarding this device.
3.2.4. MCU Socket (X1)
The BoosterPack has a footprint for a 20-pin DIP socket which allows the board to be operated
standalone. In this configuration, the MSP430G2553 is installed directly on the BoosterPack
and therefore only power and ground connections are required (i.e. there is no need to plug the
BoosterPack into the LaunchPad other than for programming the MCU). Please refer to the
MSP430G2x53 datasheet and MSP430x2xx Family User’s Guide on the TI website
(www.ti.com) for further info regarding this device. Not populated (default).
