3.1 Overview
The RYZ014A LTE Cat-M1 Cellular IoT Module Pmod™ expansion board provides an interface using a 12-
pin Digilent Pmod™ compatible connector (CN1).
This provides access to:
•A high-speed UART interface (UART0)
•A reset pin (RESET)
•A PMOD_RING pin (RING0)
•VDD and GND connections for module power
Pmod™ is registered to Digilent Inc. and its specification can be found at the link below:

Please refer to the module data sheet for full electrical specifications.
Note: This Pmod has a maximum operating current of 480 mA dependent upon the LTE band, Tx/Rx
settings, and network coverage. Please ensure that the host board can supply sufficient power or
provide supplemental USB power via CN4 to avoid RF instability.
3.6 Module Control
The high-speed UART interface can be used to communicate with the module using the AT Commands or by
using Renesas FSP if you are using an RA MCU. These commands are explained in the following document:
RYZ014 Modules User's Manual: AT Command (renesas.com)
3.7 CN2 Connector
CN2 is not fitted, this connector is for JTAG debugging the module and is not used.
3.8 CN4 Micro USB Connector
CN4 is a Micro USB connector which is used to connect to UART2 of the Module. See the module datasheet
for more details on UART2 usage.
3.9 CN6 SIM Connector
CN6 is standard Micro SIM connector.

6. Regulatory Information
This section contains general regulatory information. For a full list of requirements and integration guidelines
please refer to the RYZ014A User’s Manual.
6.1 FCC Statement
FCC-ID: 2AU6XRZ014A
This device complies with part 15 of the FCC rules. Operation is subject to the following two
conditions:
1. This device may not cause harmful interference.
2. This device must accept any interference received, including interference that may cause undesired
operation.
This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to
part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful
interference in an industrial or residential installation. This equipment generates and can radiate radio
frequency energy and, if not installed and used in accordance with the instructions, may cause harmful
interference. If this equipment does cause harmful interference to radio or television reception, which can be
determined by turning the equipment off and on, the user is encouraged to try to correct the interference by
one or more of the following measures:
•Reorient or relocate the receiving antenna.
•Increase the separation between the equipment and the receiver.
•Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
•Consult the dealer or an experienced radio/TV technician for help.
Caution: Any changes or modification not expressly approved by the party responsible for compliance could
void the user’s authority to operate the equipment.
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. This
transmitter must be co-located or operating in conjunction with any other antenna and transmitter.
