Hi there, thank you so much for your support! It is M4

Hi there, yes. The delivery takes around 5 business days.

Hi! Since the turning angle is limited to 40°, the distance is 0.173 m.

Hi there! The battery uses an SM plug. The motor uses a pH 2.0 6-pin connector.

Hi there, no worries. Pls contact our support team and we will help you for the purchase. Email: support@hiwonder.com

Currently, we provide usage routines only for STM32, Arduino, and Raspberry Pi. If you wish to connect it to the Jetson Orin Nano, personal development will be required.

Based on the specifications of our 520 encoder DC gear motor and your test results, the issue lies in a misunderstanding of the pulse count calculation—specifically, overlooking the quadrature (4x) encoding feature of the AB-phase encoder. The detailed analysis is as follows:Key motor specifications: Gear ratio: 1:30 (the motor rotates 30 times for every 1 rotation of the wheel) Magnetic ring resolution: 11 lines (the encoder outputs 11 base pulses per revolution) Encoder type: AB-phase (supports quadrature encoding, i.e., 4 pulses per line) Correct pulse count calculation: Pulses per wheel revolution = Gear ratio × Magnetic ring resolution × 4 (quadrature encoding) i.e., 30 × 11 × 4 = 1320, which matches your measured result exactly.Misunderstanding in your calculation: The quadrature feature of the AB-phase encoder was overlooked—this feature increases the base pulse count by detecting both the rising and falling edges of channels A and B, effectively multiplying the base count by 4. You either calculated only Gear ratio × Magnetic ring resolution (30 × 11 = 330), or mistakenly used a gear ratio of 90, both of which lead to incorrect results. Conclusion: The measured value of 1320 is correct. The root cause of the discrepancy is the omission of the quadrature decoding effect in the pulse calculation. The product parameters align with the actual test results, and there is no need to modify any hardcoded values.

Hello, the Ackermann chassis is constructed from 5052 aluminum alloy with an anodized surface treatment for enhanced durability.

Yes, you can use it with the Arduino Nano. However, please note that we only provide a use case for the Arduino UNO, not the Arduino Nano.

The wiring and power supply setup should be determined by the customer based on the main controller they are using. The wiring diagrams provided in our documentation can be used as a reference.The diagrams for Arduino and Raspberry Pi illustrate separate power supply connections for both the motor driver module and the main controller.
