HARDWARE FEATURES
This chapter describes the hardware features of the Wi-Fi G Demo Board.
The key features of the Wi-Fi G Demo Board are listed below and are introduced in
Section 1.3 “Functionality and
board.
2.1.1
The MRF24WG0MA IEEE 802.11 b/g Wi-Fi Transceiver Module provides wireless con-
nectivity to the demo board. Host communication is through SPI2 of the PIC processor
on the board.
2.1.2
The Wi-Fi G Demo Board is designed with a permanently mounted (soldered)
PIC32MX695F512H processor.
2.1.3
The board is powered by 2 AAA batteries. If required, the battery voltage is monitored
and boosted by the MCP1642 Synchronous Boost Regulator.
2.1.4
The LEDs: LED0 (GREEN), LED1 (YELLOW) and LED2 (RED) are connected to
PORTE and PORTF of the PIC32MX695F512H processor. To turn the LEDs ON, the
port pins are set high.
2.1.5
The Wi-Fi G Demo Board has the following switches:
• S1 – Controls the main power to the board. To turn on the board, move S1 slider
• SW0 – It is an active low push-button switch, connected to RD9 of the processor.
2.1.6
Connector J14 provides easy access to the PIC32MX695F512H processor’s debug
pins. This is used to program or reflash the demo board with new firmware.
2.1.7
Connector J15 provides access to six of the processor’s spare I/O pins. These pins can
function as general purpose I/O ports or as an SPI, I2C or UART interface to an external
circuit design.
to the ON position.
When idle, the switch is pulled high (+3.3V) and when pressed, it is grounded.
