Vishnu 50
The actual 3D design of the ESC. Turn it over and look at it from any side.
Where the Vishnu 50 goes.
Four M3 screws come up through the frame on the standard 30.5 × 30.5 mm pattern. Scroll to build it in.
Grommets first.
A soft TPE grommet presses into each mounting hole, so frame vibration stays out of the gyros. We injection-mould them ourselves.
Vishnu, then Brahma.
The Vishnu 50 slides down the screws first. The Brahma F4 sits on top. Shown here under a Brahma F4.
Four nuts. One cable.
An 8-pin cable links the two boards. Tighten four nuts, close the frame, and you are wired.
One stack.
Many machines.
Four ESCs.
One board.
Scroll to fly across the real board model.
24 MOSFETs
Six for every motor, split across both sides of the board to spread the heat.
Four drivers
One microcontroller and gate driver per motor, running BLHeli_S or BlueJay.
One 8-pin plug
Four motor signals, current and battery voltage on a single cable to any Brahma.
LiPo pads
Wide solder pads for the battery leads.
Three pads per motor
Numbered 1 to 4 on the board, so wiring is hard to get wrong.
VISHNU
50
Marked and numbered.
Current sensor
A precision shunt measures the whole pack current for the flight controller.
Direct pads
The same signals as the plug, on pads, for flexible wiring.
Make your ESC sing.
On BlueJay, the Vishnu plays a startup tune through the motors. Compose yours here, then paste it into ESC Configurator.
In ESC Configurator: connect the Vishnu, read settings, open the melody editor, paste, then write. Custom tunes need BlueJay firmware. The sound here is a preview; your motors will sound rougher.
