An upgraded Raspberry Pi Pico alternative featuring a massive 16MB QSPI Flash, USB Type-C connectivity, and built-in WS2812 RGB LED for advanced DIY and R&D projects.
We’ve all been there: you’re building a complex IoT gateway or a high-resolution display controller, and you hit the 2MB flash wall on the standard Raspberry Pi Pico. Or perhaps you’re simply tired of hunting for an old Micro-USB cable. The YD-RP2040 is the solution for power users. It takes the legendary RP2040 silicon and wraps it in a board designed for the modern workbench, featuring a USB Type-C port and a massive 16MB QSPI Flash—that’s 8 times the storage of the original Pico.
While standard clones often cut corners on flash speed and soldering quality, the YD-RP2040 is built for reliability. This board is Probots™ Lab Verified in our Bangalore facility to ensure the high-capacity flash maintains signal integrity at 133MHz clock speeds. To ensure your hardware arrives in pristine condition with perfectly straight pins, every order is packed using Probots™ Secure-Transit protocols.
Microcontroller: Dual-core ARM Cortex M0+ @ 133MHz
Memory: 264KB On-chip SRAM
Flash: 16MB (128Mbit) QSPI Flash (W25Q128)
Connectivity: USB Type-C (for power and data)
On-board IO: * 1x WS2812 RGB LED (Connected to GPIO 23)
1x Blue User LED (Connected to GPIO 25)
1x Reset Button
1x User Button (Connected to GPIO 24)
GPIO: 26 Multifunction GPIO pins (3.3V Logic)
Peripherals: 2x SPI, 2x I2C, 2x UART, 3x 12-bit ADC, 16x controllable PWM channels
Debug: 3-pin ARM Serial Wire Debug (SWD) port
Industrial Data Loggers: Store months of sensor data locally thanks to the 16MB flash.
Advanced Human Interface Devices (HID): Build custom macro pads or mechanical keyboards with USB-C.
Edge AI & Machine Learning: Run TinyML models that require larger model weights.
Retro Gaming Emulators: The extra flash is perfect for storing multiple game ROMs or assets.
Past Projects (Prerequisites): If you have mastered basic automation with an Arduino Uno or a standard 2MB Pico, you are ready for this upgrade.
Feature Upgrade: This board unlocks high-capacity file systems (LittleFS) and complex Python libraries that wouldn't fit on standard boards. The dedicated Reset and User buttons significantly speed up your debugging workflow.
Effort Level: Intermediate. It uses the same ecosystem as the Pico but requires an understanding of 3.3V logic levels.
Hardware Needed: A USB Type-C cable and a 3.3V-compatible sensor kit.
Voltage Warning: The board is powered via USB (5V) or VSYS (3.3V - 5V). However, all GPIO pins are 3.3V Logic Only. Do not connect 5V sensors directly to GPIO pins.
Probots™ Logic-Safe Tip: Always use a logic level shifter when interfacing with 5V modules like HC-SR04 or older LCDs.
Bootloader Mode: To program, hold the 'BOOT' button, press 'RESET' once, then release 'BOOT'. The board will appear as an RPI-RP2 mass storage device.
Included: 1x YD-RP2040 16MB Development Board, 2x 20-pin Male Headers (Unsoldered).
Required Additional: High-quality USB Type-C Cable, Breadboard (for prototyping).
