X650 with Raspberry Pi 3B¶
| Item | Notes |
|---|---|
| HolyBro X650 Development Kit | Pixhawk 6X, M10 GPS and a 433 MHz telemetry module (consider the allowed frequency bands in your region). The telemetry module is not a must for Drone Grid, but it is useful and nice to have |
| Raspberry Pi 3B | 1 GB RAM |
| Raspberry Pi Camera Module v2 | Do not use the V3 camera - it is not suitable for high-vibration environments |
| ESP32 development board | I cannot find the exact link but it is an old microUSB one with 38 pins |
| T8L Radio Controller | You will need two 18650 batteries - make sure they are the correct size. Choose the correct transmitter variant for your region - e.g. for Europe, ELRS is correct |
| RP2 V2 ExpressLRS 2.4ghz Nano Receiver | the most fun of all - solder pin headers to this receiver, then plug it into a servo cable (Y-harness): one end goes to the kill switch, the other to the flight controller's RC IN. Choose the correct receiver variant for your region - e.g. for Europe, ELRS is correct. |
| 4G USB modem | One of the cheapest possible ones you can buy online - it worked for a while until it didn't. I resorted to using an old phone as a Wi-Fi hotspot onboard - I am exploring which cellular HATs are more suitable |
| Waveshare UPS Hat (B) | You will need two 18650 batteries - make sure they are the correct size |
| 6S Lipo Battery 100C | You will need an XT90 to XT60 adapter |
| Lipo Battery charger | |
| A mobile data plan | An old phone (or a 4G/5G modem) is also needed for the companion's uplink - more effective hardware solutions are being explored |
