Product Name: Ewheel ADC adapter
Size: 24x34 (mm)
How many pieces do I need it in my build? and how to connect cables?
If you're using it in dual motor controller, it depends on your detail needs:
two motors work independently. ----2pcs , refer 2pcs adapter wiring diagram
two motors work in same step by can bus communication---1pc, refer to 1pc adapter wiring diagram
Why you need an adapter in applying a vesc in ADC mode?
1.The ADC input of ESC(based on VESC) is in float mode, and there is no filtering measurement. If this input port is left floating, it is easy to be interfered by electronic interference, and ESC will be misjudged by the signal voltage that requires the motor to run.
The symptom is: the throttle is unstable and easily interfered; if the throttle ADC input is unplugged or the throttle cable is disconnected, the ESC(based on vesc) is very easy to continue working to control the motor and can’s stop it.
2. Most of the ebike and scooters thorttle on the market are 5v, and such throttle control signal is accordingly above 0-4v, while the working voltage of ESC(based on VESC) is 3.3V,so the throttle signal voltage exceeds the upper limit of ESC (based on VESC), it will affect the normal operation of ESC, and even cause ESC failure
3. Due to wiring complexcity, it's easy to wiring wrongly and damage the ESC.
What's Spintend Ewheel ADC adapter advantage？
1.The ADC input is protected by filtering and pull-down to ensure the stability of the throttle signal. When the throttle signal is disconnected or unplugged, the ADC pin of the ESC can be pulled down to 0V to ensure that the ESC stops.
2.Regarding the 5V operating voltage of the adapter, the throttle signal is stepped down to meet the range of 0-3.3V to ensure the safety of the ADC input of esc.
3. It simplifies the user's wiring. With the Ewheel ADC adapter, the user only needs to plug the three wires of the accelerator and the two wires of the brake into the corresponding sockets, which can easily realize the single-drive wiring.
4. And the ewheel ADC adapter also provides a very simple parallel application capability. Based on the single-drive wiring, the dual-drive control can be realized very simply.
How to use Ehweel ADC adapter?
If your application is a single motor driving, then choose one ewheel ADC adapter
If your application is a dual motor driving, then choose TWO Ewheel ADC adapters.
