Greetings from Team 6341, we are an FRC team partnered with Interact based in Woodstock, Ga and we started on a special project known currently as PowerWheels Mobility Project. This project focuses on giving a child a chance to have fun in a custom made offroad wheelchair. We customize it based on the childs needs and use legal FRC parts for most of the project. However, due to the motor controllers known as Sparks were discontinued from REV, we are depending on prior robots. We have other teams around us who donates these motor contollers to us so we would be able to continue the project. We are asking for sparks in decent condition (new or used) to be donated to us via mail or other manners. Our team website is up and running and I left a link on the bottom for it. I also left link giving more information about the wheelchair project.
Edit: Talking to my team, we are looking for motor controllers that uses PWM, not CAN
Is this limitation due to a space requirement? The Victor 88X series is incredibly common, and most older teams will has them floating around. They should be nearly interchangeable with Sparks (both are PWM control).
From my knowledge of the project the last time I worked on it (I currently am out of the country), we have been using arduino to control the wheelchair. We found it easier to use Sparks but I will contact my team and see if these controllers would work. We are looking for motor controllers that use PWM, not CAN.
The Victor 884 and Talon SR accept essentially the same inputs / outputs. Same servo timing style, same connector, also screw terminals. I’m curious as to what design you have that wouldn’t work with one of those.
You should consider using the Victor SPX instead since the Victor SP has been discontinued and is no long available for purchase. As @bobbysq mentioned, the Victor SPX and Talon SRX can be used with both CAN and PWM. The green CAN wire goes to PWM ground (usually the black wire) and the yellow CAN wire does to PWM signal (usually the white wire). The +5v line (usually the red wire) isn’t needed on the Victor SPX or Talon SRX since this comes from a 5vdc supply inside the controller.
The CAN wires on the Victor SPX actually come with PWM connectors. One twisted pair has a female PWM connector for use with devices like an Arduino, RaspberryPI or RoboRIO. The other set has a male PWM connector for use with devices like the VEX ARM® Cortex®-based Microcontroller.
I know we have a bunch of sparks in our old inventory. We just moved to a new build space and we are still unpacking / sorting, so it may take me a little while to lay my hands on them. But we should be able to send some to you.
