 The Dronecode Mini (DCM) connector standard is intended for in-vehicle, cross-PCB use. It uses the JST GH series which offers a latch lock mechanism at small size and a very competitive cost ($0.15 / 6 pos connector footprint in quantities).

+This pinout should be used for any serial port. Ports not supporting hardware flow control should leave the CTS and RTS lines floating. Cables should be 1:1 to the periphal and TX / RX as well as CTS / RTS should be crossed on the peripheral side (e.g. a radio modem would have its RX port on pin 2, TX port on pin 3, RTS on port 4 and CTS on port 5).
