Wiring without Breakout Boards

The breakout boards shipped with the Evaluation Kit offer flexibility during exploration and prototype phase. For a tighter hardware integration, devices can be wired directly to the Pico-Clasp connectors on Skynode such that the breakout boards become obsolete.

Required tools

• Molex Pico-Clasp connectors
• Pico-Clasp crimp tool
• Pico-Clasp crimp contacts
• Alternatively Pre-crimped Pico-Clasp cables

Wiring Devices to the Pico-Clasp Connectors

Example: Freefly RTK GPS module

| Pin # on GPS JST Connector | Signal | Pin # on Pico-Clasp Primary (J4) | | :------------------------: | :---------: | :------------------------------: | | 1 | VCC_5V | 22 * | | 2 | GPS_RX | 18 | | 3 | GPS_TX | 20 | | 4 | I2C_SCL | 19 | | 5 | I2C_SDA | 21 | | 6 | BUTTON | 3 | | 7 | BUTTON_LED | 5 | | 8 | GND | 7 * |

*There are also other options to chose here as those signals appear multiple times on the Pico-Clasp connector J4. Make sure to use the correct supply voltage for your peripheral. For the GPS this would be VDD_5V_CAN1_GPS1 (pin 22 or 40). For other peripherals check the Datasheet under "Peripheral Power Domains".

{% hint style="info" %} The I2C pins exist only once one each Pico-Clasp connector. If you would like to connect multiple I2C devices on the same I2C bus you can split the I2C line using a Y-cable {% endhint %}
