DAUGHTER BOARD
The high-speed UART interface and the GPIO ports are available on the module to
configure, control, and transfer data. The RN2483 LoRa Technology PICtail/PICtail
Plus Daughter Board has PICtail and PICtail Plus connectors to interface with a PIC®
microcontroller (MCU) on the development boards that support PICtail or PICtail Plus
interface with the required pin mapping. The PICtail board also has an on-board PIC18
MCU available for custom user functions. It is preprogrammed to provide a simple
USB-to-UART serial bridge enabling easy serial connection.
Demonstration of the RN2483 is performed by plugging the daughter board into a USB
port of a PC. The USB port powers the daughter board and enables the user to
communicate using the RN2483’s ASCII commands.
Development of the RN2483 with Microchip’s PIC MCU line is possible via the 28-pin
PICtail connector to a PIC18 Explorer or 30-pin card edge PICtail Plus connector to an
Explorer 16.

1.3 CONTENTS
The package kit contents contain the following tools as listed in Table 1-1.
1.4 BOARD CONFIGURATION
Prior plugging the module into the motherboard's socket, ensure that one of the current
measure jumpers, CUR1 or CUR2, are shunted.
PICtail Daughter Board can be powered from two sources, either from one of the
PICtail headers or from USB. Both power sources can be active at the same time.
RF antennas must be connected to the SMA connectors prior attaching power to the
board.
Ensure that the applied power supply voltage does not exceed the board limits.
Figure 1-2, Figure 1-3, and Figure 1-4 show the connection to various development
boards.

Chapter 2. Getting Started
2.1 INTRODUCTION
This chapter describes the hardware requirements for RN2483 LoRa Technology
PICtail/PICtail Plus Daughter Board and also provides the different types of
communication modes.
The module accepts commands via UART interface. Basically, two communication
modes are supported by the daughter board, USB mode and PICtail mode.
PICtail mode gives more computing power to the user program, since motherboards
contain additional MCUs.
This chapter discusses the following topics:
Communication Modes
Communication to the Module
Hardware Description
2.2 COMMUNICATION MODES
2.2.1 USB mode
USB mode is initiated if the daughter board is connected to a USB port via a mini-USB
cable. In this mode, the on-board PIC18 MCU provides a USB-to-UART bridge.
Supply voltage is provided via USB and the on-board LDO (IC1) which regulates 5V to
the nominal 3.3V.
2.2.2 PICtail mode
PICtail mode is initiated if no USB cable is attached to the board and the board is
plugged into the appropriate motherboard.
When USB power is not attached, the on-board PIC18 MCU does not influence UART
communication.
2.2.3 PICtail mode with USB connected
The daughter board can be used in a third mode when it is connected to a PICtail
motherboard while the USB is also connected. It is useful when the user wants to set
the supply voltage from the PICtail connector while the communication must be
continuously active via the USB interface. The on-board PIC18 MCU takes over the
control of the UART interface. In this case, the motherboard is unable to send UART
messages to the module, however, the messages sent by the module appear on the
PICtail UART.
Note: User must ensure that PICtail/PICtail Plus port pins are fully compatible to
the pinout of the daughter board.
Note: Some motherboards may adjust the supply voltage to the attached MCU
Plug-in Module. Do not exceed the supply voltage limits of the module.
RN2483 LoRa™ Technology PICtail™/PICtail Plus Daughter Board User’s Guide
DS50002366A-page 16 Advance Information 2015 Microchip Technology Inc.
Another case is that the motherboard does not have power supply. In this case, the
motherboard can be powered from the USB together with the daughter board. User
must take care of the maximum output current of the on-board LDO, which is 500 mA.
A short on the jumper JP_RST on the daughter board forces the board to operate in
PICtail mode, although USB remains connected. The jumper JP_RST keeps the
on-board PIC18 MCU in reset state to ensure that USB-to-UART protocol translation is
not performed in this mode. If jumper JP_RST is not shorted, on-board PIC18 MCU has
the priority over the UART communication.
2.3 COMMUNICATION TO THE MODULE
In PICtail mode, the Microchip 8/16/32-bit PIC MCUs on the motherboards can run
custom functions and connect to the module using the UART interface, which accepts
ASCII commands from the host.
In USB mode, when the daughter board is connected to the host via USB, the on-board
PIC18 MCU uses the CDC class to create a USB-to-UART bridge device. The host can
run a simple terminal emulator application to issue commands.
2.4 HARDWARE DESCRIPTION
The RF signal path is connected to the SMA edge connectors. The 433 MHz band RF
signal is transmitted through RFL SMA edge connector, whereas RFH SMA connector
is used for the 868 MHz band.
The current consumption measurement of the module is supported by the on-board
current measure jumpers. If jumper CUR1 is shunted, the supply current flows directly
to the module.
There are two ways to measure current consumption:
A current meter can be connected to CUR1 jumper pins to measure the actual
current consumption of the module. CUR2 must be left open.
The current consumption graph can be recorded in the time domain by removing
the shunt from CUR1 jumper and shunting CUR2 at the same time. Use a two
channel oscilloscope, which supports subtracting mathematical function. Connect
oscilloscope probes to CUR1 jumper pins while CUR2 jumper is shunted. Set the
oscilloscope to display the difference between the two channels.
All pins of the module can be accessed via through hole pads which is located on both
sides of the module. User can mount two 1.27 mm pitched socket headers if required.
Sockets can connect the module pins to a custom board, whereas the daughter board
provides the power. The through hole pads are classified into two groups which are
located on both sides of the module. Each pad group, J1 and J2, has a dedicated pad
on which power is delivered to the custom board. The supply current is measured
together with the module's supply current. To do this, JP2 must be shorted for J2 and
JP3 for J1.
If the supply current is separated from the module, the other two jumpers must be
shorted. To power the custom board separately, shunt JP1 or JP4.
The on-board PIC18 MCU is programmable via programming port ICSP_IC2. In USB
mode, LD1 and LD2 LEDs indicate communication on the UART.
Note: Only 30-pin PICtail Plus connection is detected. If the daughter board is
attached to a 28-pin PICtail connector, the jumper JP_RST has no affect.
