FIGURE 1-1:
PICtail Connector (P1) – 28-pin right angle connector to connect to 8-bit development
boards’ PICtail connector.
PICtail Plus Connector (P2) – 30-pin card edge connector for connecting into 16 and
32-bit development boards’ PICtail Plus connector.
MRF49XA (U1) – ISM sub-GHz Transceiver.
Power Disconnect/Current Measurement Headers (JP1/JP2) – Two, 2-pin headers are
connected in parallel. A shunt connects power to the MRF49XA circuitry. A current
meter can be placed on the header and the shunt removed to measure current
consumption.
TIP: To prevent power interruption to the MRF49XA, keep the shunt on the header
while connecting the current meter. Once connected, remove the shunt to measure
current.
Antenna Connector (J1) – Populated with a receptacle pin to accept a wire antenna (24
AWG solid wire). For 433.92 MHz, the wire length is 6.8 inches. For 868/915 MHz, the
wire length is 3.3 inches.
EUI Node Identity Serial EEPROM (U2) – 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).

Do not allow shunt resistance to exceed 50 ohms as it may lower the supply
voltage to the MRF49XA and cause a glitch reset.
The receptacle can be removed and a SMA or reverse polarity SMA
connector can be soldered in place.
