Power
Detailed Description
The EV kit board can be powered directly from the FTHR
board PMIC through the H1 header, directly from the supply
test points, or through the user-installed PMOD header. The
FTHR board can provide a supply from +2.1V to +3.3V or
a single +2.1V to +3.6V, 100mA power supply can be con-
nected to the board using the two wire loops (marked VDD
and GND). Jumper JU4 selects the source of power when
not using the direct connection test points: from the L3OUT
of the FTHR board or the PVIO of the PMOD connector.
Detailed Description of Hardware
MAX7044 EV kit Printed Circuit Board
The MAX7044 EV kit PCB is manufactured on a two-layer,
1oz copper, FR4 dielectric stack-up PCB. Layer 1 is primar-
ily designed to keep the RF signals on one side of the board
with short traces, small matching components, and low
parasitics. Layer 2 is targeted to be a continuous ground
plane wherever possible. The EV kit is available in two
versions: 315MHz (MAX7044EVKIT-315) and 433.92MHz
(MAX7044EVKIT-433). The passive components are opti-
mized for these two frequencies, but can easily be changed
to work at RF frequencies anywhere from 300MHz to
450MHz.
Data Interface
The EV kit comes preconfigured to directly connect the
FTHR board through the H1/H2 headers. The GUI controls
the communication of the FTHR board and MAX7044.

EV kit with power, make sure to connect the JU4 jumper
between pins 2-3. See Appendix II for detailed information
on evaluation kit hardware modifications.
PMOD Interface
The EV kit provides a PMOD-compatible header footprint
to interface with the transmitter. The JU3 connector can be
populated with a 6-pin, 100mil, right-angle header allowing
direct connections to the CSB, DATAIN, CLKOUT, SCLK/
SDA, ground, and VDD lines. Populating this header
would allow control from the MAX32600MBED kit and the
MAXREFDES72# Arduino Uno R3 to the PMOD shield
adaptor. When using the PMOD interface to supply the
Detailed Description of Software
The MAX7044 EV kit Controller GUI software is designed
to control the MAX32630FTHR board, as shown in
Figure 3. The software utilizes USB controls to program
the FTHR board. The FTHR board is capable of providing
power and input data to the EV kit.

Comport
Data Control Section
The Comport section provides a drop-down selection of
serial communication ports available for connection to
a EV kit through an FTHR board. When the GUI is run
after connecting the EV kit hardware, the drop-down box
should default to the proper COM port. If the hardware is
connected to the computer after the GUI is started, click
the Refresh button to scan for compatible ports. Once the
appropriate COM port is selected in the drop-down box,
click the Connect button. (See Figure 6.)
This portion of the GUI software provides a flexible tool for
the user to generate data from a single-pin interface. The
GUI provides simple Manchester-encoded data to be sent
directly to the DATAIN pin of a connected device.
Manchester Bitrate
This is the data rate in kbps for Manchester-encoded data.
Enter a value in the text box and click the Set button to
configure the Data Control.
After properly connecting to the COM port with the FTHR
board, the GUI will display the revision of the FTHR board
firmware detected, display a Green LED, and display
Connected in the status bar along the bottom of the GUI
window. (See Figure 7.)
Continuous Transmission
Selecting this check box will configure the Data Control
interface so the message or data sequence will repeat until
the user interrupts the transmission. For example: when a
0xAA message is sent with Continuous unchecked, the
sequence of 1-0-1-0-1-0-1-0 bits will be transmitted a single
time. When the Continuous is checked, the Send Data
process will continuously send a repeating sequence of
1-0-1-0-1-0-1-0-1-0-1-0-1-0-1-0… bits, emulating a square-
wave data pattern.
Voltage (2.1V to 3.3V)
The Voltage section provides a user-adjustable power sup-
ply from the FTHR board MAX14690N power management
IC (PMIC) to the EV kit and can be used as the primary
VDD supply. The PMIC, L3OUT can be set to voltages
between 2.1V to 3.3V and it applies to the level of the logic
interface lines as well as the device supply. (See Figure 8.)
Messages Text Block and Message File
The Messages text block contains hexadecimal encoded
data string to be transmitted with the FTHR board over the
data interface. The data is streamed directly to the DATAIN
pin of the MAX7044 EV kit.
To program the supply voltage, enter a valid level in the
Voltage text box and click on the Set button. The default
value of the L3OUT voltage is 3.3V.
When using the FTHR board interface to supply the EV kit
with power, make sure to connect the JU4 jumper between
pins 1-2.
Tool History Section
This portion of the GUI contains a Log File text block which
is used to record activity within the GUI.

Log File
For every Set, connection effort, or register programming
action, the GUI activity is logged in this text block. The user
can add notes and make edits to the content of the Log
File text block.
Selecting File > Exit from the tool bar will close the GUI
program. This has the same effect as clicking the X button
in the upper-right corner of the GUI software.

splash screen. This window shows the name of the soft-
ware, the revision number, a copyright notice, a link to the
Maxim website, a link to the support website, and a check-
box to enable or disable the splash screen during startup.
Click the OK button to close the About window.
Clicking on the Clear Log will delete the contents in the
text block.
Clicking the Save Log button will open a Save As explorer
window and the user will be prompted to save a .txt file.
Miscellaneous Software Information
The tool bar along the top of the GUI software provides a
couple of options to the user.

a. The FTHR board LED will shut off and the LED on the MAX32625PICO slowly flashes red as the FTHR board
is being programmed.
b. Once the programming is complete, the MAX32625PICO USB drive disconnects from the PC and reconnect as
a USB Drive again.
c. If the programming was successful, the contents of the MAX32625PICO USB Drive should include a DETAILS.
TXT file. If an ERROR.TXT file exists on the drive, check that the FTHR board had power during the program-
ming process and repeat steps 3 and 4.
5) To ready the FTHR board for use, disconnect the MAX32625PICOboard (ribbon cable) and press the Reset button
on the FTHR board or disconnect the FTHR board from the USB power supply.
a. When the Reset button is pressed, the microcontroller restarts and the newly programmed application begins to
run, or you can disconnect and reconnect the USB cable if using a PC for power.
The latest information and these firmware update instructions can be found on the MAX32630FTHR board Mbed web
site or by visiting the Mbed home page and searching for “MAX32630FTHR.”

PMOD Header Interface
The MAX7044 EV kit has a PMOD-compatible header footprint that provides yet another built-in interface to the transmit-
ter. The JU4 connector can be populated with a 6-pin, 100mil, right-angle header such as a SAMTEC TSW-106-25-T-S-RA,
allowing direct connections to the CLKOUT, DATA, ground, and VDD lines.
The PMOD interface can be used in combination with the Maxim MAX32600MBED kit and the MAXREFDES72# Arduino
Uno R3-to-PMOD shield adaptor. When using the PMOD interface to supply the MAX7044 EV kit with power, make sure to
connect the JU4 jumper between pins 2-3.
