FIGURE 1-1: MRF89XAMXA PICtail™/PICtail PLUS DAUGHTER BOARD

PICtail Plus Connector (P1) – 30-pin card edge connector for connecting to the16-bit

and 32-bit development boards’ PICtail Plus connector.

PICtail Connector (P2) – 28-pin right angle connector to connect to the 8-bit develop-

ment boards’ PICtail connector.

MRF89XAM8A (U1) – Ultra Low-Power Sub-GHz transceiver module – 868 MHz.

MRF89XAM9A (U1) – Ultra Low-Power Sub-GHz transceiver module – 915 MHz.

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

MRF89XAMxA 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).

INT2 Jumper (JP3) – Jumpering JP3 with a shunt allows you to connect RA5 to

RB2/INT2, this enables push button switch S2 to trigger an interrupt. For more

information, see

Section 2.2.1 “Configuring Push Button Switch S2 to RB2/INT2”.

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 Iden

tity Data Sheet” (DS22123).
