J14 - Wireless Radio Module Power
Header J14 must be jumpered in order to use the Artaflex radio module. Placing a jumper on J14
provides 3.3V power to the P17 module socket. This power is drawn directly from the 3.3V regulator.
R20 - Multipurpose Variable Resistor
The board is equipped with a 10 k thumbwheel variable resistor referenced to ground. The high
side of the resistor is tied to jumper J11. The wiper is tied to a receptacle pin on P14.
J11 - Variable Resistor Power
Header J11 must be jumpered in order to use the variable resistor. Placing a jumper on J11 provides
VDD ANLG power to the high side of the resistor.
SW1 and SW2 - Multipurpose Push Button Switches
The board has two multipurpose mechanical push buttons, SW1 and SW2, that are referenced to
ground. The other sides of the switches are tied to receptacle pins on P14. The switches follow an
inverted logic as they connect ground to receptacle pins on P14 when pressed.
LCD Module
The board has a 2x16 alpha-numeric LCD. I/Os of the module are connected to port two of the PSoC
device and are routed to the processor module socket P2. This LCD is rated for 5V. However, the
I/Os have a level translator inline so that signaling may be as low as 1.8V and still be recognized by
the LCD. The header J12 must be jumpered for the LCD Module to be powered. If J12 is not jum-
pered, it removes power from level translator. If the LCD module is removed, the receptacle pins of
P18 can be used as port 2.
