DEVBOARD3 - ETH

Product DEVBOARD3

PIC18F67J60 TQFP64, Ethernet & SD Card connectors

The DEVBOARD3 is a proto-typing board used to quickly and easily evaluate the 10Mbits Ethernet link 10Base-T port and SD card FLASH memory.

It provides easy access to 28 IOs pins on the CPU. In order to accommodate all of the microcontroller’s on-chip peripherals the board comes with a very large proto-typing area, 362 plated-through holes and many CMS footprints. So the user can decide which peripherals to be use.

Header RS232C ( Communication / Bootloader / debbug )
362 plated-through holes proto-typing area.
CMS Footprints ( 0805, SOT23, SO16 )
Regulated power +3.3V / 800mA
RESET switch

The DEVBOARD3 is a high quality EPOXY RoHS prototype board, complete with a solder mask on both sides of the board, with a high-contrast silk-screen labeling component positions. Board size is a compact 118 x 76mm.

The board is deliver with a little application to demonstrate the Ethernet link. when power up, the DEVBOARD3 will try to retreive an IP adress from a DHCP server. If you need a different LAN configuration ( no DHCP ), please ask when you order.

WARNING: On the V1.0 PCB board, the J4 connector is NOT usable. A regrettable error was on the schematic – Sorry, it will repair for the next PCB bench. All functionalities are available with J3 – ICSP connector. You may even use the ICD2 tool from Microchip if you do a little connectors adapter.
