SAMR30 Module XPro
SAMR30 Module Xplained Pro User's Guide
Introduction
The SAMR30 Module Xplained Pro (XPro) evaluation kit is a hardware platform to evaluate the
performance of ATSAMR30M18A which is a Sub-1 GHz IEEE
®
802.15.4
™
compliant RF module. This
evaluation kit is supported by the Atmel Studio Integrated Development Platform (IDP), which provides
easy access to various ready-to-use applications supported by the Microchip ATSAMR30M18A module.
This user’s guide facilitates how to get started with the SAMR30 extension board and how to integrate the
module in a custom design. The extension board is designed to provide 802.15.4 wireless functionality to
the Xplained Pro evaluation platform in 700/800/900 MHz industrial, scientific and medical (ISM) band.

Note:��
1. The chip antenna supports only the 858-928 MHz band. The rest of the frequency bands supported
by the ATSAMR30M18A module can be evaluated through the on-board SMA connector.
2. When f
RF
=868.3 MHz, BPSK-20.
3. By default, the chip antenna is connected to the RF output of the module. The SMA connector
(J106) can be connected to the RF trace by removing L106 and mounting R115. For the schematic,
refer to SAMR30 Module XPRO design documentation on the Microchip website: https://
www.microchip.com/DevelopmentTools/ProductDetails/AC164159
4. The SMA connector is intended to be used only for laboratory evaluation purposes. For field usage
in USA/Canada, the antenna port must be of type RP(Reverse Polarity)-SMA.
