RP2040-Zero Raspberry Pi Development Board
I ordered the RP2040-Zero board mainly out of curiosity and as a backup for prototyping. The RP2040 chip has a great reputation for its price-performance ratio, and this compact version looked ideal for space-constrained builds.
It arrived in about 14 days, nicely packed in an antistatic bag. I was pleasantly surprised at the build quality—clean soldering, tight headers, and zero cosmetic defects. I flashed it using the Raspberry Pi Pico bootloader, and it worked right out of the box with MicroPython. It’s responsive, stable, and the dual-core Cortex M0+ really makes multitasking smooth for this form factor.
Pros: Tiny size, solid build, full Pico functionality, very low power consumption Cons: No onboard debug probe (understandable at this price point), no pre-soldered headers Price comparison: Under $4 here vs $8–$10 for similar boards in the US Did it meet expectations? Exceeded them. Definitely a go-to for compact embedded projects.
