Seeedstudio Grove 90 Degree 4-pin Connector (10)

I used it on a custom pcb, I was forced to bend the pins to fit as the space between them is 2mm instead of 2.54mm. Luckily the longer pins made it fairly easy.

These 90 degree 4 pin connectors are "perfect" for connecting an M5 Stack device (Core, Stick, Atom) using its Grove connector to a SparkFun 60 LED ring. The StickC plus has an RTC plus WiFi so making an LED Ring clock is so simple and the tech is fully encapsulated, fast and efficient. These connectors are used by snipping 1/2 of the pin length off then soldering to the back of the ring... They worked perfectly.

Does what it tell

The step is not 2,54 mm as usual, but, the length of pins permits, if you want, to fit 2.54 mm pcb!
