| + | * Cut one 6inch (152mm) JST-GH Cable in the middle | ||
| + | * Cut 4 parts 140mm of the yellow cable | ||
| + | * Remove 8 mm of the isolation of the JST-GH and the yellow cables on one side | ||
| + | * Make a Y cable by putting the JST-GH and two yellow cables together with the white solder sleeve. (Heat level 5-6) | ||
| + | * Make two of the above cables | ||
| + | * One of the two yellow cables will go to the right side Pi where there are connected with a Harwin M20 connector. | ||
| + | * Remove 3-4 mm isolation of the one of the yellow cables | ||
| + | * Crimp a Harwin M20 connector to the cable with the Harwin crimp tool. Use the 26-28 AWG slot. | ||
| + | * Push the cable through until you can barely see the copper - then crimp. | ||

| + | The [[https://docs.px4.io/v1.9.0/en/assembly/quick_start_pixracer.html|PixRacer Wiring Quickstart]] shows the 6 pin Telem1 and Telem2 connector wiring. We only need GND, TX and RX. GND and RX will be connected with the Y-Cable. In that image the yellow connector is the PixRacer TX port which goes to the Pi RX port. So the Y-Cable is connected to GND and the yellow pin marked "RX". | ||
| + | |||
| + | * Connect the Y cables to the 6-Pin JST-GH connector. One to GND, the other one to the pin marked "RX" | ||
| + | * Take an 8-inch JST-GH cable and remove the connector at one side. Remove 5mm of the isolation at the other. | ||
| + | * Put this cable in the JST-GH connector at the location marked "TX". This is the UART RX port of the PixRacer. | ||

| + | Now the power connections from the PowerModule are left. | ||

| + | * Take two 6-inch JST-GH cables and remove the connector at one side | ||
| + | * Crimp the Harwin M20 connector at that side | ||
| + | * Insert the JST-GH Cables in pin 1 and 3 of the JST-GH 4 pin power connector | ||
