MCP2200 USB to Serial Converter
The MCP2200, with the associated driver, makes the F1 LV Evaluation platform appear
as a serial port when connected to a PC. The demo code includes utilities to control the
various add-on boards through this serial interface.

1.3.5
Two Push Buttons, One Potentiometer, 7 LEDs
Simple applications need the basic user interface elements. Two push buttons, one
potentiometer and 4 green LEDs are available for any application. The remaining three
LEDs are used as indicators, a red LED is used to indicate the board is powered, the
remaining two LEDs are green and indicate RX/TX communication through the USB
Serial Converter.

One Custom LCD
The LCD glass supplied on this board is a Microchip custom display with icons for a
battery indicator, 4 large numerical digits, 2 small numerical digits, adjustable decimal
point, colon for time keeping, 4 function mode (Fx) indicators, 8 segment bar, a
three-segment battery power indicator and 1 custom Microchip symbol. The
PIC16LF1947 makes controlling the LCD very simple.

20-pin Add-on Connector
This connector expands the F1 LV Evaluation Board with optional add-on boards.
Currently, there are 4 motor control add-ons planned or in production. The
PIC16LF1947 has complete control of 3 phases, so other 1, 2, or 3-phase motor
topologies are supported.

Current Monitoring Connector
To demonstrate the Extreme Low Power (XLP) features of the PIC16LF1947, a
precision ammeter can be connected to the current monitoring connector. This allows
your application to be easily optimized for the lowest possible current.

MCP1640 Synchronous Boost Regulator
The MCP1640 is a compact, high-efficiency, fixed frequency, synchronous step-up
DC-DC converter. Through the use of this component, the F1 LV Evaluation board has
the option of boosting an AAA 1.8V battery to 3.3V, which is then used to power the
board and supporting circuitry.

MCP1703 LDO Regulator
The MCP1703 is a low-dropout voltage regulator with a 250 mA maximum output.
Through the use of this component, the user has the option of powering the F1 LV
Evaluation board through the USB Serial Converter connector. The USB supplies 5V,
and the MCP1703 reduces this to the operating voltage of 3.3V.
