Electrical¶
Power¶
Veronte can use unregulated DC (6.5V to 36V). Pins used for power and ground are the same for both Ground and Air configurations.
LiPo batteries between 2S and 8S can be used without regulation needs. Remaining battery level can be controlled by the internal voltage sensor and by configuring the voltage warnings on the Pipe software.
For higher voltage installations, voltage regulators must be used. For dimensioning voltage regulators take into account that a blocked servo can activate regulator thermal protection.
Warning
Caution!! Power Veronte out of the given range can cause irreversible damage to the system. Please read carefully the manual before powering the system.
Veronte and servos can be powered by the same or different batteries. In case of having more than one battery on the system, a single point ground union is needed to ensure a good performance. The ground signal should be isolated from other noisy ground references (e.g. engines). If all grounds need to be connected, the connection should be made on the negative pole of the battery.
It is recommendable to use independent switches for autopilot and motor/actuators. During the system initialization, the PWM signal will be set to low level (0V), please make sure that actuators/motor connected support this behaviour before installing a single switch for the whole system.

Flight Termination System (FTS)¶

Flight Termination System
Veronte integrates two different FTS pins (42 and 43):
FTS1 - Deadman (Pin 42): On this pin, Veronte outputs a square wave with A = ~5ms and B = ~5ms (3.3V). Its frequency can be higher right after the rebooting (around 300-400Hz), but A and B must be always < 8ms.
FTS2 - !SystemOK (Pin 43): Its output is 0V when the system is working as expected and 3.3V when some error is detected. In detail, pin 43 goes high if A > 8ms or B > 8ms in the deadman signal sent by the Main Processor Unit (MPU).
Joystick¶
To use the joystick in the system, connect the PPMout of the trainer port to a digital input of Veronte and configure that digital input as the radio input in Pipe.
If the PPM level is 3.3V, pins 1-8, 10-17 and 55-58 pins can be used.
Veronte is compatible with standard Pulse Positon Modulation (PPM) signals, Futaba radios between 8 and 12 channels are recommended.

PPM signal
As default, channel 8 is reserved for manual / auto switch. High level is used for automatic flight and low level for manual control. This channel can be configured on Veronte Pipe.
Warning
Caution!! PPM signal must be into the Veronte voltage ranges. Some joysticks may need an adaptation board, please ask our team to check compatibility.
Veronte connector for CS is provided with 3.5mm stereo plug connector as follows:
