AfroESC 20A 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 www.flyingtech.co.
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 20A has a lightweight BEC, capable of about 0.
power at 200. Low-voltage cut-off (input voltage checking) and temperature limiting are not enabled, as reacting to such conditions on a multi-rotor will likely be worse than ignoring them. Always use a LiPo battery alarm or telemetry to avoid over-discharging LiPo batteries! General Operation Once an input signal is received that is low enough to reach the “neutral” or power-off area, the ESC will arm (long beep), and the green LED will light.
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. KK2 boards have a two-button procedure that performs automatical calibration. With KK boards, the Yaw pot must be set to the minimum position in order to enable pass-through mode from the receiver input to the ESC output, and the ESCs are then calibrated to the radio's throttle throw.
To aid with troubleshooting, the AfroESC sports “ready” (green) and “error” (red) LEDs. During power-up, the MOSFETs and drive circuitry are checked to ensure correct operation. During this test, it may be unsafe to beep an error. If no beeps are heard from the motor, check to see if the error LED is flashing, which should be visible through the heat-shrink.
or was not able to signal proper status, so to prevent motor or other damage, the ESC reset itself. Check for moisture problems or strong fields right next to the ESC. If nothing is found, the MCU may be faulty. Once a valid input is connected and the ESC is sees an idle power request, a long beep 4 is played and the green LED lit to indicate that the ESC is armed. This is required for all input sources, and must be maintained at a rate of at least 20Hz, or power will be switched off.
