AfroESC 30A USER MANUAL

Thank you for purchasing AfroESC, with a high efficiency, all N-channel MOSFET design, jitter-free

hardware PWM input, and smooth power response! The AfroESC series ship with SimonK software,

suitable for multi-rotor use without the need to program or adjust settings.

Caution

With any new build or after making any changes, always test carefully in a controlled environment.

Ensure propellers rotate in the correct direction and are tightened, that all signal connections are

in the right order and firmly connected. Motors connected in the wrong order may result in

uncontrolled flips. Never attempt to stop propellers by hand, and maintain a safe distance at all

times.

The AfroESC 30A has a lightweight BEC, capable of about 0.5A, which should be sufficient to power

most flight boards, but not servos. A dedicated BEC is recommended where servos or other

devices are used.

There is NO protection against reverse polarity, which would reduce efficiency and add weight. Be

sure that you connect RED to POSITIVE (+V) and BLACK to GROUND when wiring or attaching

bullets to avoid damage.

Software and Updates If desired, the firmware may be upgraded and/or customized to enable or disable various features such as complementary PWM, brake, RC-Car mode, or adjust default settings such as endpoints and motor timing. The firmware can be updated using similar procedures as for the KK(2) and other projects based on ATmega hardware. For source code, binaries, and other information, see http://github.com/sim-/tgy/ and http://0x.ca/tgy/.

With normal PWM input, ESCs and flight boards should be configured to match the expected working range. If unmatched, the motors may not start until higher throttle signal is given, may start “hot” even with a low throttle, may reach full power early, or may not reach full power. In many cases, end-point calibration is not required unless the flight board outputs different ranges. First, remove all propellers! Check to see if there are calibration steps documented for your flight controller board.

indicated by beeping through the motor and LED flashing. There are four main beep pitches: Beep Beep Beep Beep 1: 2: 3: 4: Lowest pitch (also red LED). Medium-low pitch (also green LED). Medium-high pitch (no LEDs) Highest pitch (also red and green LEDs together). Beeps 1, 2, and 3: Normal power-up with no special event detected. A longer beep 4 normally follows to indicate that an arming signal was detected. Beep 3, beep 1: Voltage brown-out detected (MCU voltage dropped below 4.0V).
