RP2040-PiZero Development Board
Versatile RP2040 Board with DVI Output and Raspberry Pi Zero Form Factor
The RP2040PiZero is a highperformance, costeffective microcontroller board designed by Waveshare [citation:1][citation:9]. Based on the Raspberry Pi RP2040 dualcore processor, it features a 16MB Flash and 264KB SRAM, and adopts the popular Raspberry Pi Zero form factor [citation:1][citation:6].
RP2040 DualCore Processor 133MHz ARM Cortex M0+ with 264KB SRAM
16MB Onboard Flash - Large storage capacity for complex firmware
Operating voltage is 3.3V for logic, with 5V input via USB-C
Use the 40-pin GPIO header for compatibility with some Raspberry Pi HATs [citation:1]
DVI and PIO-USB functions are only supported in C/C++ environment and cannot be used simultaneously [citation:1][citation:10]

CostEffective Alternative RP2040 performance with Raspberry Pi Zero form factor
Versatile Interfaces - DVI, USB, SD card, and battery support in one board
√ Compatible with C/C++, MicroPython, and Arduino
√ USB mass storage for draganddrop programming
√ Waveshare provides comprehensive SDK and tutorials [citation:1][citation:10]
Programming Environment
Supports multiple development environments including C/C+ SDK, MicroPython, and Arduino IDE [citation:1][citation:10]. For DVI and PIO-USB functionality, C/C+ environment is required [citation:1][citation:10].
Note: The DVI interface and PIO-USB port are powerful additions but are mutually exclusive in use and require C language programming [citation:1][citation:10].
Troubleshooting
No display output:
- Ensure HDMI screen is DVI-compatible
- Use C/C++ environment for DVI functionality
- Check Mini HDMI cable connection
USB device not detected:
- Verify PIO-USB firmware is correctly configured
- Ensure C/C++ environment is used
- Check power supply to connected device
