PICtail Plus Connector (P1) – 30-pin card edge connector for connecting into 16 and
32-bit development boards’ PICtail Plus connector.
PICtail Connector (P2) – 28-pin right angle connector to connect to 8-bit development
boards’ PICtail connector.
MRF24J40MA (U1) – IEEE 802.15.4 2.4 GHz Transceiver.
MRF24J40MB (U2) – IEEE 802.15.4 2.4 GHz 20 dBm Transceiver.
Power Disconnect/Current Measure Jumpers (JP1/JP2) – Two 2-pin headers are
connected in parallel. A shunt connects power to the MRF24J40 module. A current
meter can be placed on the header and the shunt removed to measure current
consumption.
TIP: To prevent power interruption to the MRF24J40 module, keep the shunt on the
header while connecting the current meter. Once connected, remove the shunt to
measure current.
INT2 Jumper (JP3) – Jumpering JP3 with a shunt allows the connection of RA5 to
RB2/INT2 to allow push button switch S2 to trigger an interrupt. See Section 2.1.1
Configuring Push Button Switch S2 to RB2/INT2 for more information.
EUI Node Identity Serial EEPROM (U3) – Contains a unique IEEE EUI address. For
more information, refer to “2K SPI Bus Serial EEPROM with EUI-48™ Node Identity
Data Sheet” (DS22123).
Note: Only one MRF24J40 module, U1 or U2, will be populated on the
PICtail/PICtail Plus Daughter Board depending on the development tool
ordered.
