Summary

Hover a connector to identify it — click to jump to its pinout.

Board-to-Board Connectors

P6 and P7 are Hirose DF40HC(4.0)-60DS-0.4V(51) 60-pin connectors with a 4 mm mate height. They mate with the VOXL 2 Mini camera group connectors J6 and J7.

P6 - Camera Group 0 (mates to VOXL 2 Mini J6)

P6 carries CSI0 (J0 and J6 tracking sensors) and CSI1 (J1 hires sensor), plus the CAM0 SPI0 port used by Lepton 1.

P7 - Camera Group 1 (mates to VOXL 2 Mini J7)

P7 carries CSI2 (J2 thermal sensor, two lanes) and CSI3 (J3 hires sensor). GPIO_4 and GPIO_5 (QUP1) run in I2C mode and serve the barometer, the TCA9543A Lepton I2C mux, the VTX I2C on J7, and J2.

Image Sensor Interfaces

• requires kernel m0104-1-var00.2-kernel.img

MIPI Connection Details

Support Camera Configs

Notes for Sensors

• supported coax cables
  • MCBL-00084
• HW synchronization
  • tracking sensors enabled sync by default using GPIO 109 (voxl-fsync-mod)
  • hires sensors are not synced by default: their sync pins (J1 and J3 pin 21) connect to GPIO 109 only through R10 and R11, which are not fitted
  • the Boson+ on J2 receives GPIO 109 directly on pin 17
• connectors
  • J0, J1, J2, J3, and J6 are Hirose DF56C-26S-0.3V(51) 26-pin micro-coax receptacles

J0 - Tracking Sensor ID0

• supported image sensors
  • M0166 - 1280x800 Global Shutter Sensor AR0144
• 2 MIPI lane support, in combo mode with Sensor ID6

J1 - Hires Sensor ID1

• supported image sensors
  • M0161 - 4k High-resolution, Low-light, IMX412
• 4 MIPI lane support

J2 - Thermal Sensor ID2

• supported image sensors
  • Boson+ (M0201 backpack)
• 2 MIPI lane support

J3 - Hires Sensor ID3

• supported image sensors
  • M0161 - 4k High-resolution, Low-light, IMX412
• 4 MIPI lane support

J6 - Tracking Sensor ID6

• supported image sensors
  • M0166 - 1280x800 Global Shutter Sensor AR0144
• 2 MIPI lane support, in combo mode with Sensor ID0

FLIR Lepton Interfaces

Lepton 1 - J10

J10 and J5 are JST SM08B-SRSS-TB 8-pin 1.0 mm connectors with the same pinout. The SPI, I2C, and clock lines run at 2.8 V, and the board’s level translators and 25 MHz oscillator handle the conversion.

Lepton 2 - J5 (external SPI to M0104 J10)

Lepton 2’s SPI comes from VOXL 2 Mini J10 through J4, not from the camera group connectors.

J4 - SPI from VOXL 2 Mini J10

J4 is a JST SM06B-SRSS-TB 6-pin 1.0 mm connector. It takes the 3.3 V SPI port from VOXL 2 Mini J10 and passes it to Lepton 2 on J5. The MCBL-00120-1 cable converts J10’s 8-pin GH connector to this 6-pin SH connector.

ModalAI VTX I2C Interface

dev/i2c-0 - ADC address 0x1D, Temp Sensor address 0x48

J7 is a JST SM03B-SRSS-TB 3-pin 1.0 mm connector.

Software

Linux Users Guide

Lepton 1 - J10

The /dev/spidev0.0 SPI interface comes through M0195 P6, the /dev/i2c-0 I2C inteface comes though M0195 P7.

I2C is shared between Lepton 1 and Lepton 2 and we need to use a channel selector.

For Lepton 1 I2C, you need to use CHANNEL0 of the TCA9543A device (write 0x01 to address 0x01 on slave device 0x73).

Lepton 2 - J5 (external SPI to M0204 J10)

The /dev/spidev14.0 SPI interface comes through J4 that connects to M0104 J10 externally, the /dev/i2c-0 I2C inteface comes though P7.

I2C is shared between Lepton 1 and Lepton 2 and we need to use a channel selector.

For I2C, you can use CHANNEL1 of the TCA9543A device (write 0x02 to address 0x01 on slave device 0x73).

Baromter Interface

A ICP-10100 barometer is exposed on /dev/i2c-0 (address 0x63) when M0195 attached to M0204 (VOXL2 Mini)

I2C Mux Interfaces

A 2 channel I2C mux (TCA9543A) is on the /dev/i2c-0 bus at address 0x73 when mated to VOXL2 Mini.
