Open source lithium battery management board, charging 5V2A, discharging 5V/1.52A or 12V/0.76A

This DIY LiPo super charger can charge a single LiPo battery and protect it from overvoltage, overload and short circuit. In addition, it can boost the battery voltage to 5 V or 12 V. The boosted output voltage is protected by an "eFuse" IC with a maximum output current of 1.52 A at 5 V and 0.76 A at 12 V. The charger part of the circuit requires a +5V power supply, which can be connected via USB-C, or simply solder two wires to pads on the PCB. Additionally, other connections can be soldered to pads on the PCB or use individual pin headers.

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).

Voice and vision module based on ESP32S3

Use ESP32S3 to develop a general module with speech recognition and visual recognition functions. It is mainly used for education, science and technology competitions, and creative design of DIY enthusiasts. The interface and functions are compatible with OpenMV, and its IDE can be used as development and debugging software. Most of the overall hardware design is compatible with ESP32S-EYE, so with a little adjustment of the interface definition, it can be compatible with ESP-WHO. ESP-WHO provides examples such as face detection, face recognition, cat face detection and gesture recognition, thus making this software The module is very playable.
