The survey grade magnetic GNSS/GPS antenna mount is a rugged solution that allows for quick and stable mounting to metal surfaces without the need for drilling. Equipped with a standard 5/8" 11-TPI thread and designed to protect the TNC cable, it provides durability and convenience for stationary surveying applications. SparkFun PRT-21257

A compact Hall-effect current sensor that provides accurate DC and AC current measurement within a ±10 A range with galvanic isolation. It features a high-sensitivity analog VOUT output with a 150 kHz bandwidth, enabling fast and precise readings in dynamic systems. The module operates over a wide temperature range of -40°C to 125°C, and its low current path resistance (~1.6 mΩ) minimizes energy loss. Its small size and flexible mounting options make it ideal for prototyping, industrial systems, and space-constrained projects. Pololu 5450

Water-based paint that can conduct electricity. It allows you to paint wires on various objects, such as models, clothes, furniture, walls. Standard acrylic or water-based paints can be used with Electric Paint to act as insulation or create multi-layer circuits. It is black and packed in easy-to-use 10 ml sachets. SparkFun COM-22958

GNSS module based on the mosaic-X5 system from Septentrio. This compact GNSS receiver delivers centimeter-level accuracy with high data update rates. It supports multiple satellite constellations including GPS (US), GLONASS (Russia), Beidou (China), Galileo (Europe) and NavIC (India), as well as regional systems such as SBAS and QZSS.
