Seeedstudio Grove 4-pin Connector (10)

Didn't give any issues when used correctly

Seeedstudio's Grove Connector system is getting popular with lots of sensors and peripheral devices available. You can get them directly from Seeedstudio of course, but in the US you'll wait (or pay $$$) for shipping. Robotshop offers a great price for a handy connector! Oh yeah, these are made to solder on a PCB, not for building cables. ;-)

had to modify the pins to fit on board

This wasn't what we needed, it turns out. We thought this was the one needed for Benewake TFMINI Micro LIDAR Module UART (12 m) (USD $39.00).

well made, generally std. but nice
