MRF24J40ME PICTAIL™/ PICTAIL PLUS DAUGHTER BOARD
PICtail Plus Connector (P1)
– 30-pin card edge connector for connecting into 16-bit
and 32-bit development boards’ PICtail Plus connectors.
PICtail Connector (P2)
– 28-pin right angle connector to connect to 8-bit development
boards’ PICtail connector.
MRF24J40ME (U2)
– 2.4 GHz IEEE 802.15.4 RF Transceiver Module.
Power Disconnect/Current Measure Jumpers (JP1/JP2)
– Two 2-pin headers are
connected in parallel. A shunt on one of the two headers connects power to the
MRF24J40ME module. A current meter can be placed on the open header and when
the shunt is removed from the opposite header, current consumption can be measured
without interrupting power. A useful cable that can be connected to the 2-pin header
and current meter, using banana plugs, is the XLP Current Measurement Cable
(AC002023).
External Antenna
– 2 dBi dipole whip antenna (P/N RFA-02-L2H1-70B-150 from
Aristotle Enterprises Inc.).
INT2 Jumper (JP3)
– Jumpering JP3 with a shunt allows you to connect RA5 to
RB2/INT2. This enables push button switch S2 on the PIC18 Explorer to trigger an
interrupt. For more information, see
Section 2.2.1 “Configuring Push Button Switch
EUI Node Identity Serial EEPROM (U3)
– Contains a unique IEEE EUI address. For
more information, refer to the “
2K SPI Bus Serial EEPROM with EUI-48™ Node Identity
Data Sheet”
(DS22123).
