Since the power current of the module is very large, please do not artificially short-circuit when the module is not working normally. Once the short circuit may burn the line and burst the tube, the first wiring test Please test with low current and low voltage. After ok, then pass high current and high voltage. Since it is a bare board module, pay attention to the insulation of the wiring terminal. It is strictly forbidden to touch the parts on the board with strong voltage. 3.Don't connect the motor that is obviously inconsistent with the voltage, current and power of the drive module or far away from each other, to avoid inexplicable ""no point"" damage.

It was pretty fast! **Q: Is there a data sheet for the whole board, i need to know how it works and it building blocks. A deep review of the chips like JY01 and its mosfets.** A: not in this package, not at all **Q: Does the pot have to be turned to zero before the brake is activated? Or will toggling the brake disable the drive? Can brake act as on/off switch?** A: 1. No need to zero 2. Yes, braking (brake) has the highest priority 3. It can be used as on-off function, but not equal to on-off ## Customer Reviews ### ⭐⭐⭐⭐⭐ Wire it correctly. *by J***E on 10 August 2026* Product came quickly. Potentiometer included. Works as it described. Make sure not to cross polarity. When connecting device. Thank you ### ⭐⭐⭐ funcional *by J***S on 20 February 2022* es funcional y cumple con su cometido sin embargo al arranque tiene un pequeño retraso de 1 segundo ### ⭐⭐⭐⭐⭐ Worked great for me, but WATCH OUT - many questions/answers are for another product *by B***T on 3 May 2023* Note - many of the questions/answers displayed for this item are actually for the Hall Sensor version so please be careful and don't assume all those answers apply to this module. This listing is for the "Hall-less" version, meaning it's for controlling a 3-phase DC motor that only has 3 wires and does NOT use hall sensor monitoring. Some errors I noted in the Q/A section: - some Q/A indicate the module has "soft-start" - it does not, but see my easy hack to add it below* - some say to "remove the jumper" to use the external analog speed control - there is no jumper on this module, just be sure to set the on-board speed pot to zero (full ccw) - some say this module will not work with a Hall-less motor - that is WRONG, it is specifically designed to work with hall-less motors. - there are several different wiring diagrams shown in the listing, but the one that has pictures of the motor and power supply is what I used and seems to be correct. I used this controller to operate the fan motor from an EGO leaf blower that was trashed because the internal controller died. My fan motor has 3 leads - red, blue, and yellow, which connect to the controller terminals red to red, blue to blue, and yellow to green. I'll use this fan blower with some 18v cordless tool batteries as a sweeper in my shop and patio, and 18v yields plenty of air flow for that purpose. * I made a simple modification to perform a soft-start function, using a 470uf capacitor and a 1k resistor (see photo and video). Some experimenting proved that the external potentiometer speed control reaches maximum motor speed at about 4.6v, which can be achieved by placing a 1k resistor from the 5v terminal to the analog speed input. By adding the capacitor, the voltage on the speed input slowly rises when power is applied, so that the motor speed ramps up from zero to full speed in about a second, greatly reducing the strain on the power supply, controller, and the motor. If you want a slower start-up you can increase the size of the capacitor, but leave the resistor at 1k. If you increase the resistance above 1000Ω the motor will never reach full speed. ## Frequently Bought Together - RioRand 300W 5-50V PWM DC Brushless Electric Motor Speed Controller with Hall-Less - Nano V3.0, Nano Board ATmega328P 5V 16M Micro-Controller Board Compatible with Arduino IDE (Nano x 3 with USB Cable) - ELEGOO 120pcs Multicolored Dupont Wire 40pin Male to Female, 40pin Male to Male, 40pin Female to Female Breadboard Jumper Ribbon Cables Kit Compatible with Arduino Projects --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/401857637-380w-6-5-50v-pwm-dc-brushless-electric-motor-speed](https://www.desertcart.tn/products/401857637-380w-6-5-50v-pwm-dc-brushless-electric-motor-speed) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-09-17*
