Product description:

The transceiver module is a complete RF receiver and transmitter, suited for exchanging data with a data rate up to 256 kbit/s. The transceiver module is an efficient receiver with a high sensitivity and an efficient transmitter with high power output. Because of the SMD construction, the module has a very small shape.
The module can be controlled directly by a microcontroller with SPI interface. This way the total hardware of the system can be limited to a minimum.

The module is available for the 433 MHz en 868 MHz ISM frequency bands used in Europe.
The module comes in three different packages: DIL, SMD1 (S1) en SMD2 (S2).
The S2 package is normal stock.

* under specific conditions:
The range depends on the following parameters:
- TX power
- RX sensitivity
- Data rate
- Transmitter bandwidth
- Receiver bandwidth
- Antenna height
- Antenna type
- Radio protocol
- Etc.

** Using 2 modules of the same type, maximum TX power and a data rate of 1200 bit/s.

We gebruiken deze modules voor draadloze bedieningsknoppen en -panelen. De modules zijn erg zuinig, wat een voordeel is bij batterij-gevoede apparaten. Helaas trekt de module wel te veel stroom voor een CR2032 batterij (tijdens het zenden en ontvangen).

Ik heb deze module gebruikt voor onderzoek naar time-of-flight metingen met low-cost hardware. Op dit gebied niet echt een aanrader, voor de rest zeker wel! De modules zijn gebaseerd op de Si4432 chip van Silicon Labs. Mocht de datasheet soms wat onduidelijk zijn dan kan je eventueel hier een kijkje nemen. Eén nadeel van de modules is dat ze een 2 mm spacing hebben tussen de aansluitpunten. Wanneer je ze dus wil gebruiken op een prototype circuit board met 2.54 mm spacing dan zul je wat moeten knutselen. verder zijn het echt topmodules! Wanneer je er een massa nodig hebt kun je wel beter voor de RFM69 gaan aangezien de Si443x chips momenteel in de end-of-life status zitten en niet meer geproduceerd worden.

Expertly and passionately, Ideetron turns your ideas
into reality. We focus on clarifying the technological
chaos between man and machine. Ideetron is
specialized in product development in the field
of electronics.
We translate ideas into complete end products
entirely according to the wishes of the customer.

At Ideetron we believe that there is a suitable
solution for every electronic problem.
When designing electronics, extra attention
is paid to the following factors: cost price,
performance and service life.

Our projects consist of customization and are built
with electronic components. Ideetron is also not
a system integrator, which means that all
subsystems are designed by Ideetron.
The projects are personally taken care of at all
times and can be requested at any time.
We make an analysis with regard to
the electronic problem or the optimal technical
interpretation for your application. Based on the
analysis made, Ideetron draws up one or more
solutions from which you can make a choice.

Our experience in the field of product development
offers us the opportunity to realize reproducibility.
Most problems in the field of electronics are
existing problems. In most cases, we have already
gained knowledge and insights from these existing
problems, you can benefit from them.
