MattTheGeek 99 Posted May 26, 2012 Share Posted May 26, 2012 MotorPack 4 CH motor controller booster pack The MotorPack Booster Pack is a 4 CH motor controller based off the DRV8830 from Texas Instruments. Key Features Drive up to 4 DC motors at 1A per channel (External power supply is required) Easy and IO saving I2C interface (Only 3 GPIO pins required) Motor Fault Detection Stackable! (Hopefully) Status: PCB Routing I'm rerouting the PCB for the addition of the address select logic GeekDoc 1 Quote Link to post Share on other sites
MattTheGeek 99 Posted May 31, 2012 Author Share Posted May 31, 2012 Still need to calculate some resistor values, etc... bluehash and fatihinanc 2 Quote Link to post Share on other sites
bluehash 1,581 Posted June 2, 2012 Share Posted June 2, 2012 Let me know when you are ready to make PCBs. Quote Link to post Share on other sites
MattTheGeek 99 Posted June 3, 2012 Author Share Posted June 3, 2012 Changed the design a bit: Fuse has been replaced with a 4 amp PTC.Enhanced reverse voltage protection. No voltage drop.Schematic fixes. Almost done with layout. Quote Link to post Share on other sites
MattTheGeek 99 Posted October 4, 2012 Author Share Posted October 4, 2012 Got the MotorPack to version 2. I'm currently optimizing the routing and doing silkscreen. It should be ready to be sent off to seeedstudio by Friday. An assembled board shouldn't cost more than $24.99 or so. Quote Link to post Share on other sites
MattTheGeek 99 Posted October 4, 2012 Author Share Posted October 4, 2012 Version 2 of the MotorPack, almost ready for seeed. And no, i didn't go crazy with the vias bluehash 1 Quote Link to post Share on other sites
GeekDoc 226 Posted October 5, 2012 Share Posted October 5, 2012 Can you do a quick BOM so I can order some parts to have on hand? Quote Link to post Share on other sites
MattTheGeek 99 Posted October 5, 2012 Author Share Posted October 5, 2012 BOM 4x - DRV8830DGQ*1x - TLV70433DBV1x - TXS0102DCU 1x - 2N3904 NPN transistor in SOT-23 7x - 0.1uF ceramic capacitor in 0805 1x - 1uF ceramic capacitor in 08051x - 10uF electrolytic capacitor in EIA3216 1x - 4.7K carbon resistor in 08051x - 10K carbon resistor in 0805 5x - 3.5MM screw terminals2x - 10 pin headers of your choice.1x - 2 pin jumper *I might be changing out the TLV70433DBV for something else that is stocked on digikey.

MattTheGeek 99 Posted November 1, 2012 Author Share Posted November 1, 2012 Added address select logic into design, which should hopefully allow users to stack another motorpack onto the launchpad and use both at the same time. Quote Link to post Share on other sites
