3.2.1. A2530 Radio Module (U6)
The Anaren A2530 module is a 2.4GHz IEEE 802.15.4 compliant radio running the Texas
Instruments ZNP protocol. For details regarding the radio module, refer to the A2530E24x and
A2530R24x User’s Manuals located on the CD provided in the BoosterPack kit.
3.2.2. MCU & Socket (U5)
The BoosterPack has a 20-pin DIP socket with a MSP430G2553 MCU pre-installed. This
allows for operation of the BoosterPack while installed on a LaunchPad board or standalone.
Please refer to the MSP430G2x53 datasheet and MSP430x2xx Family User’s Guide on the TI
website for further info regarding this device.
3.2.3. Sensors

RGB Light Sensor (U2)
The TAOS TCS3414 Digital Color Sensor (I
2
C) measures the color of ambient light and
reports the measurements in 16-bit RGBC (Red/Green/Blue/Clear) format. Please refer
to the TCS3414 datasheet on the TAOS website for further info regarding this device.
The I
2
C bus address of this device is 0x39.

IR Temperature Sensor (U3)
The Texas Instruments TMP006 Infrared Thermopile Sensor (I
2
C) measures the
temperate of an object without the need to make contact with the object (-40C to +125C
operating range). Please refer to the TMP006 datasheet on the TI website for further
info regarding this device.
Please note the BoosterPack itself is rated to +85C and should not be subjected to
ambient temperatures above this limit.
The I
2
C bus address of this device is 0x40.

Current Sensor (U4)
The Texas Instruments INA216A2 Current Shunt Monitor (analog) amplifies the voltage
across a current sense resistor with a gain of 50. Please refer to the INA216 datasheet
on the TI website for further info regarding this device.
T
he sensor’s analog output is routed to MSP430 pin P1.4 where it can be sampled using
the
MCU’s internal ADC. The measured voltage can be used to calculate the current
draw of the A2530 only or that of the entire board. The selection is made by setting
jumper JP1 to the desired position (see section 3.2.7 for information on setting the
jumper). To calculate current flowing through the 0.2
Ω sense resistor, simply divide the
measured voltage by 10 (I
shunt
= V
shunt
/ R
shunt
, where R
shunt
= 0.2
Ω and V
shunt
= V
meas
/ 50).
