The Rail-mounted TTL to RS232 Converter (B) ensures safe and stable data transmission in systems requiring galvanic isolation. Designed for point-to-point communication between TTL and RS232 devices, it is ideal for industrial environments, automation systems, and IoT projects. With its compact enclosure and wide range of protections, it provides a reliable solution for serial interface conversion.

The PCIe TO 2-CH M.2 HAT+ expands the functionality of the Raspberry Pi 5 by enabling the installation of two NVMe SSDs, offering significantly improved read/write performance and the option to boot from disk. With its compact design, support for 2230/2242 form factors, and built-in power monitoring, the adapter is well-suited for server solutions, NAS projects, multimedia systems, and advanced industrial applications.

The sensors operate from 2.7 V to 18 V and provide digital outputs that can be connected directly to a microcontroller or other digital circuit. This module is compatible with all of the Pololu dual-shaft mini plastic gearmotors. Pololu 1523

The liquid flow sensor is made of a plastic body, a flow rotor and a Hall sensor. DFRobot SEN0217

This Bluetooth Audio receiver module includes a USB port and TF card slot. With a pre-amp output, you can drive headphones or a 3W speaker directly. You can also add an active power amplifier and connect a loudspeaker. The module supports MP3, WMA, WAV and lossless FLAC audio formats. DFRobot TEL0108
