Specifications The Just Cuz Robotics WEKA Dual Brushed 20A ESC Parameters Specification Details Input Voltage 7.5V – 30V (2S to 6S LiHV battery) Channels 2 Motor Type Brushed Maximum Continuous Current Per Channel 20 amps PCB Length 30mm PCB Width 20mm PCB Height 3.5mm Weight 3g with no wires, about 12g with included wires/connectors WEKA Features First ESC with “Simon Says” calibration for motor direction, mixing, and braking Current Limiting (will prevent damaging the ESC by limiting motor current, but will not protect motors from overheating) Overtemp and Overcurrent Protection Low Voltage Cutoff Reversible Optional braking on board Optional mixing on board Includes BEC (Battery Eliminator Circuit) 5V 150mA regulator WIRING NOTES: Motor Connections: Wire the included XT30U for power, or your own power source, with red to the BATT and black to BATT-. Wire up the motors with red and black wires, or included red JST connectors, so one motor goes to M1A and M1B, the other to M2A and M2B. Servo Connections: CH1: Black – GND CH1: Red -5V (BEC / regulator output) CH1: White – S1 (Channel 1 signal) CH2: Remove the red and black wires CH2: White – S2 (Channel 2 signal) Notes: The 5v regulator is not strong enough to run big or strong servos – it is intended for powering electronics only. If using more than one ESC that has a built-in BEC, it is recommended to connect only one 5v pin to the receiver, so the regulators aren’t “fighting” each other. Mixing is enabled by default. This makes it so radio CH1 is forward/reverse on BOTH motors, and CH2 is for steering. This is perfect for pistol grip radios or one-stick arcade-style driving. To disable mixing for tank-style driving, see the calibration procedure instructions in the user guide. Some firm tugs can pull wires out of the servo connectors that plug into your receiver. We recommend adding a dab of hot glue to the wires where they join into the connector to act as a bit of strain relief and prevent this. This goes for any servo-style connectors, not just those on the WEKA. ItGresa Robotics is proud to support the builder community by offering and marketing their products.
