Basic ESC Documentation (New)

Introduction

NOTE: This is the new version of the Basic ESC, the documentation for old version is located here (http://docs.bluerobotics.com/besc/).
This new version of the Basic ESC is based on the BLHeli_S ESC design, providing an upgrade with newer technology, additional features, and improved performance. The Basic ESC is a
simple brushless sensorless speed controller pre-programmed with custom rmware that allows forward and backward operation. The BLHeli_S rmware is open source and available on
Github (https://github.com/bitdump/BLHeli/tree/master/BLHeli_S%20SiLabs).

Safety


When working with electricity, especially in water, always practice caution. Always ensure that connections are secure and watertight. Keep your body away from spinning motors
and propellers.

Quick Start

1. Connect the three motor wires to the motor. The order of connections does not matter, however, switching any two wires will change the direction of the motor. The output phases A, B, and C are
completely interchangeable
2. Connect the red power wire and black ground wire to a power source like a battery. You will hear three beeps in rising pitch from the motor indicating all three phases are connected.
3. Connect the signal cable to your signal source like an RC radio receiver or microcontroller board. The white wire is the signal wire.
4. Send a stopped signal (1500 microseconds) for a few seconds to initialize the ESC. You will hear two tones indicating initialization, and then you can send a signal from 1100-1900µs to operate the
thruster.
