MS-DIP/SO7 PCB, for SMD SSOP8-SSOP56, TSSOP8-TSSOP56

A module with a high precision temperature sensor based on the MCP9808 chip. It communicates via the I2C interface. Adafruit 1782

A compact Hall-effect current sensor that provides accurate DC and AC current measurement within a ±30 A range with galvanic isolation. It features an analog VOUT output with a sensitivity of 44 mV/A and 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 the 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 5441
