The most widespread Li-ion charger controller chip — TP4056. Here you can find tested circuit diagram and printed circuit board (full KiCad project) with TP4056and USB Type-C connector, that compatible with Power Delivery chargers (5V 3A output).

Assembling Android oscilloscope based on STM32F401/STM32F411 microcontroller with additional WiFi SoC ESP32 module, that give a chance to get wireless Wi-Fi connection and remotely monitoring signals.

Instruction to convert your Altium Designer PCB (.PcbDoc) to KiCad (.kicad_pcb).

Here is a full build instruction of 2CH USB Type-C Android oscilloscope based on STM32F401/STM32F411 board. Another one feature of this device is possibility to wireless Wi-Fi connection, that give a chance of remotely signals monitoring, but it needs ESP32 in addition.
