How it works
The Tinymesh RF Transceiver Modules are compact surface-mounted high performance modules for wireless mesh networking applications.
The modules feature a fully embedded Tinymesh multi-hop protocol stack with automatic network forming and self-healing features. It supports a full duplex UART with handshake for easy
RS232/422/485 wire replacement and ModBus RTU compatibility, analogue- pulse- and digital inputs for flexible configuration, as well as PWM and digital outputs. In addition, serial application data entered on the UART port is transported automatically to the desired destination node without further interaction from any external processor. Simple and uncomplicated data transfers.
The modules are completely shielded and available as low power, high power and long range ultra-narrowband versions. In addition, they are pre-certified for operation in license free bands from 169 MHz to 2.4 GHz.

When designing the PCB layout for the RF modules, there are some measures that need to be taken to get the best performance from the radio module. In this application note, we will suggest some best practices for your product to succeed. |
||
Different applications and different use-cases will need different wireless connectivity technologies. Therefore, selecting the right wireless technology is a critical design decision. Based on radio performance requirements and other criteria, this selection guide will point out the differences between the technologies to help selecting the right one. |
||
This is a short Application Note on the use of license free RF modules in New Zealand, and in particular which modules from Radiocrafts will meet the local radio regulations. |
||
There are many different wireless standards and technologies available to enable the internet of things (IoT). The different technologies have different pro’s and con’s depending on the use case and the end customer. Trying to keep up with the latest wireless trends can drain a company of all its resources and take attention from its core business. The solution recommended by Radiocrafts is to use a modular approach and a common RF module footprint that enables all the technologies offered by Radiocrafts without modifications to the PCB. |
||
Making a good RF antenna is by some considered a challenging part of a wireless product design. It required RF knowledge which is not common among general electrical design engineer and not widespread know-how among software engineers either. Radiocrafts has developed a process and the tools required to make this tuning process simple and straightforward in a way that a person with no RF experience can tune a 169MHz antenna to the final product. |
||
When selecting the right radio technology, the achievable communication range is an important factor. This document review how to analyse radio range based on parameter provided in the data sheets for the different module families. Some measurement results from practical range testing are also shown |
||
The purpose of this document is to list some of the most common issues that customers report when using Radiocrafts modules, and the solution to these issues. |
||
Radiocrafts offers a wide range of wireless modules targeting different solutions word-wide. This Application Note informs how to select and use Radiocrafts modules for FCC compliance in US. |
||
“This Application Note describes how to use the TM-CCT to enable and disable encryption and for entering new 16-bytes AES128 encryption key.” |
||
“TinyMesh features a unique locator function as part of the comprehensive embedded control and monitoring features embedded in the protocol. This Application Note describes the location features in more detail.” |
||
“The Radiocrafts Demo Boards and USB-sticks include an on-board firmware upgrade connector compatible with different flash programming adapters. It is also recommended that PCB layouts include a connector for firmware upgrade. This Application Note describes how to upgrade the firmware of any Radiocrafts RFmodule using either a CC Debugger or the FlashPro-CC tools.” |
||
The RC1xx0 and RC2x00 series of RF Modules with integrated protocol offers easy adaptation of wireless communication utilizing a simple UART serial interface. In their standard versions without any required configuration the modules offer two pins for controlling PA, LNA and SPDTs for signal switching. Two SPDTs are required since it is only one RF pin on the Radiocrafts modules. |
