I have a robotic arm which I want to control using Pico W. The issue is the arm has 5 motors but I was only able to find driver boards (such as https://www.pishop.us/product/robotics-board-for-raspberry-pi-pico/) which can handle up to 4 motors. Are there any boards I can chain, etc. to be able to connect the 5 motors to Pico?
- 1It would help if you can put in some more detail about the motors. Are they servo motors? Brushed DC and Brushless are controlled differently from servo motors and each other. There are a couple of servo motor hats which will support up to 16 servos. – NomadMaker yesterday
- 1The motors are simple 2-wire DC motors. I don’t know the exact model. The original setup is each motor is powered by 2 D batteries and a switch that reverses polarity so it can turn in both directions. – Alexander Vorobiev yesterday
- 1What prevents you from using two 4-motor or five 1-motor h-bridge drivers? If you only need fwd/rev/stop control, that’s 2 digital signals per motor – Abel yesterday
- 1Could you please paste pictures of the motors into your question? Or the URL of their project page. – NomadMaker 23 hours ago
- 1please focus your question so that it relates to the Raspberry Pi … right now the Raspberry Pi is irrelevant … also remove any “shopping” content – jsotola 8 hours ago
