I/O Ports

PWM Ports (JR)

Inputs

The VEKTOR Core has 6 PWM input ports, numbered from 1 to 6. These ports can be selectively assigned one of three working modes:

1. PWM Input Mode: To capture signals from receivers.
2. RPM Input Mode: To capture High-Low levels from Hall sensors and magnets.
3. Limit switch input Mode: To capture High-Low levels from Hall sensors and magnets.

As PWM inputs

When set to this operation mode, the PWM input port will receive pulse width modulation with a 20 ms duty cycle, which is typical for RC receiver outputs. In this PWM input mode, the port value will reflect a range between 1000 µs and 2000 µs, corresponding to the physical input received.

As RPM inputs

To get accurate readings, connect our Hall RPM meters to the port with the same polarity as the PWM wires.

When set as RPM meter, the port value will contain the actual RPM count.

The RPM meters can detect rotations from 100 RPM up to 6000 RPM.

As Limit switch input

When this option is selected, the port will output a value of 1000 µs when the button or switch is not pressed and 2000 µs when it is pressed. To use this feature, connect a limit switch to the port that closes the circuit between the ground pin and the signal pin. We have these switches available.

Outputs

The output ports function on a 20 ms duty cycle, with adjustable values ranging from 500 µs to 2500 µs. The configurator allows for the assignment of almost all available functions and controllers to these ports.

JST Ports

Receiver input (USART8)

It is possible to connect a commercial remote control to the VEKTOR Core. We recommend using common serial protocols for this purpose.

The VEKTOR Core supports both PWM ports and serial protocols for remote control with a hardware sender.

These two methods, PWM and serial protocols, are not mutually exclusive and can be used concurrently.

An adapter cable from JST-GH04 to JR is included in the packaging. The power supply for the receiver must be provided separately, such as through a JR patch cable.

Supported protocols

The VEKTOR Core listens on the configured port for incoming control packets. The activation order of sender and receiver is in most cases not import. The system will synchronize itself.

Radio control

The blue LED can be configurad to light up once valid packets are detected.

Port	Protocol	Sub-protocol	Channels
USART8	FlySky AFHDS-2A	IBUS-PWM	Up to 16
USART8	FUTABA	S.BUS	Up to 16
USART8	HoTT	SUMD	Up to 32
USART8	ELRS	S.BUS, SUMD, (CRSF Q1 25')	Up to 32

For short-distance applications (up to 500 meters), we recommend using IBUS receivers, particularly the IA6B receivers paired with Radiomaster transmitters for optimal performance and easy configuration.

For longer-distance applications, we advise using ExpressLRS (ELRS) for a more reliable connection.

Configurator

Set the desired RX protocol in the USART 8 (X5) tab. Then save the configuration to the flash and reboot/reset the module.

In the right RX preview stream, the serial rx channels should be visible.
