The Crowtail-SIM808-GPRS-GSM+GPS-V1.1 module combines GSM/GPRS wireless communication functions and GPS localization in a single board. Thanks to support for AT commands and standard connectors, it is used in mobile projects, GPS tracking and remote data transmission.

A compact Hall-effect current sensor that provides accurate DC and AC current measurement within a ±30 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 5453
