INTRODUCTION:
This small and compact board will give you the opportunity to add Internet
connectivity to any of your existing design or machine. Packed in compact plastic
enclosure with DB2 male connector for the microcontroller ports and with the
unique PoE (Power over Ethernet) feature which allows PIC-MICRO-WEB to take
power by the Ethernet cable and with no need for external power supply adapter.
The TCP-IP stack provided by Microchip is free of charge and royalties and allows
you to do http, ftp, e-mail etc services. You can control the PIC GPIOs by web
interface and to acquire and send data from external sensors to other Internet
applications and clients. With 128K Flash memory for programs and 128KB Flash
memory for web storage this small device have all resources usually needed for
general embedded Internet applications and interface of sensors and machines to
Internet.
BOARD FEATURES:
PIC18F67J60 microcontroller with Ethernet and 1 Mbit memory for code
1Mbit on board serial flash for web pages storage
mini ICSP/ICD connector for programming with PIC-ICD2, PIC-ICD2-TINY and
PIC-ICD2-POCKET.
Power-Over-Ethernet support (for use with MOD-PoE power supply injector on
standard LAN cables/switches)
It is possible to use the board without PoE in which case DB2 .pin8 (Vin) should
be connected to 24- 0 VDC source
The board is enclosed in plastic shell DB2 parallel port
2 available signals and power supply on the DB2 connector
Dimensions 0x30 mm (2 x 1.2")
ELECTROSTATIC WARNING:
The PIC-MICRO-WEB board is shipped in protective anti-static packaging. The
board must not be subject to high electrostatic potentials. General practice for
working with static sensitive devices should be applied when working with this
board.
BOARD USE REQUIREMENTS:
Cables: 1.8 meter USB A-B cable to connect PIC-KIT3. Other cables might be
required in case of other programming/debugging tools. You will also
need a LAN cable.
Hardware: Programmer/Debugger – PIC-KIT3 or other compatible
programming/debugging tool.

MOD-PoE – module that provides Power-Over-Ethernet. If you don't
want to use this module, you should apply power (24- 0VDC)
directly to DB2 .pin8.

POWER SUPPLY CIRCUIT:
PIC-MICRO-WEB takes power over Ethernet using the module MOD-PoE. Other
possibility is 24- 0VDC to be directly applied to DB2 .pin8 if MOD-PoE is not to be
used.
The board power consumption depends on the applied power supply and may
vary. At 24VDC the consumption is about 40 mA.
RESET CIRCUIT:
PIC-MICRO-WEB reset circuit is made with R20 (10k) pull-up, R13 (330Ω) and
capacitor C31 (100nF).
CLOCK CIRCUIT:
Quartz crystal 2 MHz is connected to PIC18F67J60 pin 39 clock in (OSC1/CLKI)
and pin 40 clock out (OSC2/CLKO).
Quartz crystal 32.768 kHz is connected to PIC18F67J60 pin 29 (T1OSI) and pin 30
(T1OSO) and supplies the Timer1.
JUMPER DESCRIPTION:
3.3V_E
enables 3.3 V power supply for the PIC18F67J60 and all other
dev ces.
Default state is closed.
INPUT/OUTPUT:
Status red LED connected to PIC18F2 J10 pin 44 (PORTB.RB4/KBI0).
