This board allows to rapidly use RFTide modules as Slave units, but that may act as Master unit as well. It contains a 5V RFTide module, one supply stage, two input and output pins that are available on a convenient terminal board.

The printed circuit board is supplied as ready for use and screenprinted, and it is sufficient to weld the few components to create a general purpose Slave unit. This circuit has been thought, in fact, to be directly wired at switches and limit switches and, by means of two relays, one may directly command small low voltage engines.

By adding externally some power relays, it is however possible to manage power loads, even at 230 Vac. The antenna may be a simple piece of rigid copper wire, 85 mm long tuned on the frequency of 868 MHz. The printed circuit board also has a connector for serial communication, to which a USB/TTL converter (optional) can be easily connected. For his power source, it is enough to use a small non-stabilized 9-12 V power supply. This breakout has the availability of two GPIN0 and GPIN1 digital inputs in positive logic, that is to say, the closing contact is connected between the input and +5V. Two digital outputs of the relay ON/OFF type are available, and the GPOUT0 pin can be configured as PWM output, depending on the usage necessities of the module.

In the ON/OFF mode, the two lines are used to activate two relays but, by inverting the jumpers on PWM, the GPOUT0 output will be available on the terminal named PWM, by means of a power MOSFET. A jumper is available for the module activation, and by disconnecting it the module goes in standby mode, with very low consumption. The P1 button can be used for the LEARN procedure, that is to say, to include a module within the network; to complete the module there is a LED operating as power supply monitor and a learning confirmation LED.

This project comes in kit. Some components have to be soldered to the included PCB.
