Subject: Help needed: Control ST-DXT-J20 V5.5 hoverboard motherboard with Arduino / ESP32

[tawanda2020-wq]

Hello everyone — I need help and I’m willing to pay for a token of appreciation for working guidance, code, or a full service.

I bought a hoverboard mainboard "ST-DXT-J20 V5.5" (MCU: Artery AT32F413RCT7) with the sensor boards YST-BT-J20 V1.1 (Board A) and YST-TLY-J20 V3.2 (Board B). Photo of my exact hardware is attached and the same board can be seen here: https://articulo.mercadolibre.com.co/MCO-564082696-board-malumeta-hoverboard-con-sensores-bogota-segway-_JM

i have been following these discussions but i am going no way coz the board is quietly diferent from those green ones and seem to be current version.

What I need:
A proven method (hardware wiring + firmware) to control the board from an Arduino / ESP32.
Ability to control both motors independently** and simultaneously:

• Variable speeds (smooth control; not just on/off)
• Direction control (forward/reverse)
• Read useful feedback from the board: RPM (or hall sensor counts), battery status (voltage / % / current if available), and any fault codes or status flags.
• Full pinout / connector mapping (which connector/pin provides motor outputs, hall sensor inputs, battery sense, UART/CAN/SPI/I2C lines, etc.).
• Example firmware/sketches or libraries (ESP32 preferred) that actually work with this board (or step-by-step instructions to do it myself).
• Any tricks for disabling the built-in self-balancing controller or safely taking low-level control of motor drivers.
• Safety guidance for bench-testing (power source, wiring, emergency stop).

What I’m offering:
I dont mind paying for verified working code, wiring diagrams, and a short walkthrough (money via PayPal or another agreed method). Payment amount negotiable based on the deliverables and proof of working setup.
I can provide additional photos or short videos of the board connectors on request.

If you have successfully done this (or have reverse-engineered similar ST-DXT-J20 boards), please reply here or send a direct message. In your reply, please state:

1. What exactly you have (board version, MCU, sensor board versions).
2. Whether you used Arduino, ESP32, or a different controller.
3. What interfaces/protocols were used (UART, CAN, PWM, analog, I²C, SPI, direct MCU GPIO/hall reads, etc.).
4. A short proof (photo of your working setup, sample serial output, or a short video).
5. Your price and preferred payment method.

This is urgent for a varsity project deadline — any immediate pointers, pinouts, or small snippets that demonstrate reading RPM or commanding motor speed will be hugely appreciated. Thank you in advance.
