It sounds like you're looking for the (circuit diagram) for a device labeled YDRP2040 . However, this identifier is not a standard, widely known module from major brands like Raspberry Pi (RP2040), Waveshare, or Adafruit.
On the YDRP2040 schematic, you will likely find a (e.g., RT6150 or similar) stepping down 5V (from USB) to 3.3V. That 3.3V then feeds an internal regulator inside the RP2040 to generate the 1.1V rail. Pro tip: Check for ferrite beads and large decoupling capacitors (10µF + 100nF) near the power pins. ydrp2040 schematic
If you’ve just gotten your hands on a board, you might have noticed that official documentation is sparse. The YDRP2040 is part of a new wave of third-party RP2040 microcontrollers designed to offer a specific pinout or form factor—often for embedded projects, custom keyboards, or industrial controls. schematic It sounds like you're looking for the
Below is a minimal, clear schematic description for a YDRP2040-based board (RP2040 MCU module with typical peripherals). Use this as a layout guide rather than a finished PCB design. That 3
The USB portion of the schematic (Micro-USB or USB-C) includes:
