Perfect for DartBox Drive gearmotors and any other brushed beetle drive solution! This ESC is able to power two independent DartBox gearmotors for a powerful, nimble robot drivetrain (or even four or more motors in some applications). This ESC has configuration options that can be changed via your transmitter. (Default is mixing enabled, braking disabled). And weighs in at just 22 grams with a smaller footprint than a Tarakan!

  • Input voltage: 9V - 18V (2S to 4S LiPo battery)
  • Channels: 2
  • Motor type: brushed
  • Maximum continuous current per channel: 15 amps
  • Reversible: yes
  • Braking: yes (optional)
  • Mixing: yes (optional)
  • PCB size: 30 x 49 x 8.5 mm [CAD Mockup available here]
  • BEC (Battery Eliminator Circuit/regulator): +5V 1 amp maximum regulator (Do not use servos with this! Receivers are fine.)

Power input - Black / Red with 18AWG silicone wire and Deans style connector. We recommend replacing this with an XT30U connector. Observe correct polarity!

Signal input - 2x “Dupont” style servo leads. Connect a receiver or other controller. The three connections are color coded:

  • Black - Ground
  • Red +5V (BEC / regulator output)
  • White - M1/Steering input
  • Yellow - M2/Throttle input

Normally these are connected to channels 1&2 on an RC receiver. The internal regulator can supply power to the receiver.

Motor output - connect wires and/or connectors of your choice to connect two brushed motors. These should accept the voltage supplied and have a maximum stall current of 12 Amps each. Ships with long wires and JST connectors, but shortening them is recommended.


2X 15A ESC Overview and Usage

See the video below for usage details!

This ESC is designed to be used with the 3-pin connector white signal wire on Channel 1 and 1-pin yellow signal wire on Channel 2 of a receiver.

This ESC allows you to change settings by setting your transmitter stick to different positions while you power on the ESC. You have to turn it off and on again to change settings, only one can be changed per power cycle. If you have any channels reversed or switched around, the stick positions will be different for you than shown here so you may need to play around a bit.

  • Stick position Upper Right: Mixing Enable/Disable (default: Enabled, Disabled makes each channel control one motor for “tank drive”)
  • Stick position Lower Right: Braking Enable/Disable (default: Disabled, recommend changing to Enabled)
  • Stick position Lower Left: Acceleration Low/Medium/High (default: medium, recommend setting to High)
  • Stick position Upper Left: “Linear Mode” Low/Medium/High (this feature seems to be broken and causes jitter, leave it at the default/smoothest setting)

Note about the BEC

The 5v regulator is not strong enough to run big or strong servos - it is intended for powering a receiver only.

Make sure to ONLY use ONE BEC to power your receiver! If you have an external BEC, cut the red wire from the 3 pin connector. If you are using a weapon ESC with a BEC, cut the red wire from that one and use the BEC on this instead as drive ESCs are less likely to die.
