Based on STM32G431, a compact closed-loop servo driver designed for NEMA17 (42mm) stepper motors

Schematic PCB

An open source project for underwater sensor nodes based on single-pair Ethernet technology SPE (from tutorial to actual combat, English)

Single-Pair-Ethernet technology (SPE, Single-Pair-Ethernet) describes the transmission of Ethernet through only a pair of copper cores. In addition to transmitting data through Ethernet, it can also simultaneously provide power to terminal devices through PoDL (power supply over data lines).
