- https://gnss.store/gnss-rtk-multiband-antennas/218-elt0181.html (needs to be mounted somewhere on top of the case)
- all antennas need to be oriented vertically, in case of ProDrone and GliderDesignParts one antenna leg vertically, the other one horizontally
- only the Taoglas and the Nooelec bundle antennas are hinged so make sure to order an SMA adapter (angled) for all other antennas according to your needs
- both ProDrone and GliderDesignParts antennas can be custom ordered with either a straight or an angled SMA connector
- Lilygo T-Beam S3 Core u-blox M10S board: https://www.aliexpress.com/item/1005005418286231.html (please select CORE UBLOX 868MHz)
- a 7mm hole needs to be drilled for the 868MHz transmitter antenna pigtail connector
- the included GPS antenna needs to be attached outside of the case
- as an alternative you can use any other GPS antenna type (a U.FL/SMA female pigtail cable is required and a 7mm hole needs to be drilled)
- a short USB-A to USB-C cable is required to connect the module to the Pi's USB ports
- the transmitter module can simply be glued on top of the Raspberry Pi copper heatsink
