1.4 Notation
Throughout SoftBaugh documentation, we follow a standard convention to identify
boards, jumpers, other components, and pins.
1.4.1 Boards, Components and Pins
The following notation is used to identify boards, components, and pins:
Board:Component.Pin
Example:
ES449:J12.5 identifies the bootloader header ground pin on the ES449.
Where obvious from the context, the Board: portion may be omitted. If an entire
component rather than a single pin is being identified, then the .Pin portion is omitted.
1.4.2 Jumpers
Unless otherwise noted, pin 1 on a jumper is always square (observed from
underneath), and the silkscreen designator for the jumper is near pin 1. Where
ambiguity could exist, a small '1' is placed near pin 1. Pins are numbered across the
short axis of the jumper first, and then down the long axis.
Jumper settings are indicated by the following notation:
Jumper.Pin-Pin
Jumper.Open
Example:
J20.1-2
A jumper block is to be placed across pin 1 and pin 2 on J20.
In the special case of two-pin jumpers, such as those used to route power or measure
current, the entire jumper may be treated as a SPST switch, and "opened".
Example:
J18.Open
J18 is left open, with no jumper block. In other sources this is referred to as "hanging"
the jumper.

3. Power Supplies
The ES449 can be operated from a variety of power supplies, depending on the options
chosen with jumper J20. This chapter discusses the most common options. In all
cases, MSP current can be isolated and measured via J17.
3.1 External Regulated Lab Supply
The ES449 can operate from a regulated 1.8 to 3.6v supply connected at J20.2, .4, .6,
.8, or .10. See section 3.7 for details.
3.2 External Unregulated Lab Supply
The ES449 can operate from an unregulated external lab supply (3.6v to 6v) by
connecting it to J8, with J20.1-2 jumpered. Refer to the ES449 schematics for details.
Adjusting the value of R27 programs the output voltage of the TPS7201.
Table 3-1 TPS7201 Output Voltage Programming Guide

2.0 118 169
2.7 215 169
3.0 261 169
3.3 301 169
3.6 348 169
*1% values shown
3.3 External Wallmount Supply
The ES449 can be operated from an external wallmount supply via the TPS7201 LDO
by connecting it to J7 and jumpering J20.1-2. The power connector is a 2.1 mm barrel
connector:
Figure 3-1 DC Power Connector
Page 16 of 35

SoftBaugh ES449 User’s Guide
The board has a 1W zener diode (D6) to protect the on-board voltage regulators against
power fluctuations. Please note that most wall-mount power supplies have voltage
ratings based on maximum load. It is important to obtain a power supply with an open
circuit voltage no greater than 4-6 volts. The SB6V power supply is recommended.
3.4 Single-Cell with Capacitive Charge-Pump
The ES449 can be operated with a single alkaline cell by use of the TPS60310
capacitive charge-pump with J18.1-2 jumpered and J20.3-4 jumpered. B2 is an AAA
socket provided for your convenience. Battery current can be measured through J18.
The capacitive charge pump can be disabled via TP9. A power good flag is available at
TP10. See the TPS60310 datasheet for more details.
If desired, a coin cell backup can be used in conjunction with this supply through D7 by
jumpering J20.9-10. When the TPS60310 is disabled, unregulated coin cell power will
continue to supply the ES449.
3.5 Unregulated Single-Cell Supply
The ES449 can be operated with a single 3v lithium coin cell by jumpering J20.7-8. B1
is a CR2032 socket provided for your convenience.
3.6 Regulated Single Cell Supply with Capacitive Charge Pump
The ES449 can be operated with a fixed 3.3v output from the coin cell using the
TPS60212 charge pump by jumpering J19.1-2 and jumpering J20.5-6. This charge
pump can be controlled via TP8 if desired. Battery current to the regulator can be
measured through J19.
If desired, a coin cell backup can be used in conjunction with this supply through D7 by
jumpering J17.9-10. When the TPS60212 is disabled, unregulated coin cell power will
continue to supply the ES449.

4. RS232 Interface
To implement a UART with the MSP430F44x requires use of either on-chip hardware
UART. Use J21 to connect TX and RX to either UART0 or UART1 on the MSP430F44x.
Texas Instruments has a variety of software samples for UART communication available
on their website. See section 2.1.20 for the communication configuration header jumper
options.
The header J21 allows normal communication or loopback operation, as shown in the
schematic, for testing either or both ends of the interface.
The MAX3221 RS232 interface allows operation in a wide variety of modes; refer to the
datasheet for full details. The most common modes are discussed in this chapter.
The header J13 and resistors R1, R2, and R3 configure the MAX3221.
4.1 Always On
As originally shipped, the ES449 permits operation with the MAX3221 in "always-on"
mode. This mode will not provide the greatest power savings, but is the most
convenient for starting projects:
Table 4-1 RS232 Always On
Item Condition Remarks
J13.1 Open 0 if no valid RS232 levels applied from host, 1 if host is connected.
J13.2 Open
J13.3 Open
J13.4 Open
R1 100k
R2 100k
R3 100k
4.2 Disabled
If communication is not required, the MAX3221 can be disabled in the lowest-power
mode by using the following settings:
Table 4-2 RS232 Disabled
Item Condition Remarks
J13.1 Open N/a
J13.2 VCC /EN disables receivers when held high
J13.3 GND /FORCEOFF forces powerdown when held low

4.3 Auto Powerdown
The lowest-power mode for RS232 operation is shown below:
Table 4-3 RS232 Auto-Powerdown
Item Condition Remarks
J13.1 Open 0 if no valid RS232 levels applied from host, 1 if host is connected.
J13.2 Open
J13.3 Open
J13.4 GND Bring FORCEON low allows auto-powerdown mode
R1 100k
R2 Open
R3 100k
In this mode, the MAX3221 can wake the processor via J13.1 if a host port is connected.
The MAX3221 will manage its own power in this mode.
