-====== ​Dronecode ​Autopilot Connector Standard ======+====== ​Pixhawk ​Autopilot Connector Standard ======
  
-This document describes the connector series and pinouts Dronecode has standardized. ​The long-term goal is to offer several tiers of connectors:+The [[https://​pixhawk.org/​pixhawk-connector-standard|Pixhawk Autopilot Connector Standard]] ​is documented on Pixhawk.org.
  
-  * Miniaturein-vehicle: JST GH +> Notethis was originally referred ​to as the "Dronecode ​Autopilot Connector ​Standard".
-  * Small, IPX9 or similar, automotive grade and sealed: This has not entered the standardization process. +
- +
- +
-===== CAN Tranceivers ===== +
- +
-These types are recommended:​ +
- +
-  * TJA1051TK3/​118 +
-  * LTC2875 +
- +
-===== Dronecode Mini ===== +
- +
-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). +

- +
-===== Pinouts ===== +
- +
-==== Telemetry Port ==== +
- +
-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). +

-==== GPS port ==== +
- +
-This port is intended for combined serial plus I2C GPS units. +

-==== CAN ==== +
- +
-Recommended CAN transceivers:​ ''​TJA1051TK3/​118''​ or ''​LTC2875''​ +
- +
-^ Pin      ^ Signal ​   ^  Volt   ^ +

-| 4 (blk)  | GND       | GND     | +

-==== SPI port ==== +
- +
-This port is optional and for external SPI sensors. +
- +
-^ Pin      ^ Signal ​   ^  Volt   ^ +
-| 1 (red)  | VCC       | +5V     | +
-| 2 (blk)  | SPI_EXT_SCK ​   | +3.3   | +

-| 7 (blk)  | GND       | GND     | +
- +
-==== ANALOG POWER ==== +
- +
-The CURRENT signal should carry an analog voltage from 0-3.3V for 0-60A as default. For high-power units the range should be 0-3.3V for 0-120A. The VOLTAGE signal should carry an analog voltage from 0-3.3V for 0-50A as default. +
- +
-The VCC lines have to offer at least 2.5A continuous and should default to 5.3V. A lower voltage of 5V is still acceptable, but discouraged. +

-===== Dronecode ​Debug ===== +
- +
-To facilitate debug and service cables, Dronecode has developed several debug connectors, of which the Dronecode mini debug connector has entered active service. +
- +
-==== DCD-Mini ==== +
- +
-**NOTE: THIS IS NOT THE SAME CONNECTOR SERIES AS FOR THE REGULAR PORTS** +
- +
-Dronecode debug port ([[http://​www.digikey.com/​product-detail/​en/​jst-sales-america-inc/​SM06B-SRSS-TB(LF)(SN)/​455-1806-1-ND/​926877|JST SM06B connector]]). The indicated voltage is nominal 3.3V, but for a target running at a lower voltage (e.g. 1.8V) the debug probe should shift its voltage to the target sense voltage. Up to 100 mA should be provided on ''​TARGET PROCESSOR VOLTAGE''​ so that debug adapters can drive their shifter / optocoupler directly from this line. +
- +
- +
-^ Pin      ^ Signal ​   ^  Volt   ^ +
-| 1 (red)  | TARGET PROCESSOR VOLTAGE ​ | +1.8V-3.3V ​    | +
