How Can We Help?
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 peripheral 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 pin2, TX port on pin 3, RTS on port 4 and CTS on port 5).
Basic GPS port
This port is intended for combined serial plus I2C GPS units.
CAN
Recommended CAN transceivers: TJA1051TK3/118 or LTC2875. Ensure o twist the wires. Please refer to the UAVCAN specification, section 7.2 for further details.
I2C port
SPI port
This port is optional and for external SPI sensors.
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.
