make me a microcontroller PCB with many GPIO pins and more. for example. 5 GND pins. 24 GPIO connecting pins. a USB-C port for power and data, a built in battery. and wifi. using the STM32 processor.
I can design this, but I can’t execute project changes right now because this account has no available ACUs.
Nothing has been added to the project yet. The requested board would likely use an STM32 MCU with enough I/O, a USB-C connector wired for power/data, a LiPo battery charger/power path, a Wi‑Fi module or STM32 wireless variant, and external headers exposing at least 24 GPIO plus 5 GND pins.
Key items still to decide before schematic capture:
Exact STM32 family: general STM32 + Wi‑Fi module, or STM32WB/STM32WBA for wireless features.
Battery type/capacity: typically single-cell LiPo/Li-ion.
USB-C role: device-only for programming/data/power, or USB-PD capable.
GPIO header format: 2.54 mm breadboard-friendly headers vs smaller SMD connectors.
Programming/debug interface: SWD header, USB bootloader, or both.
Board size constraints.
Once ACUs are available, I can create the schematic, select parts, wire USB-C/power/battery/Wi‑Fi/GPIO headers, add firmware and bring-up documentation, then verify the design.
Wirelessly connects nets on schematic. Used to organize schematics and separate functional blocks. To wirelessly connect net portals, give them same designator. #portal
