Product Features: Adopt RP2040 microcontroller chip Equipped with a dual-core ARM Cortex M0+ processor, the operating frequency is up to 133MHz flexible clockBuilt-in 264KB SRAM and 2MB on-chip Flash The real stamp hole design can be directly welded and integrated into the bottom plate designed by the user. USB1.1 host and device support Supports low power sleep and hibernate modes Drag-and-drop program download via USB recognition as mass storage 29 GPIO pins of RP2040 are led out (20 can be led out through pin headers, and the rest can only be led out by soldering) 2 SPIs, 2 12Cs, 2 UARTs, 4 12-bit ADCs, 16 controllable PWM channels. Accurate on-chip clocks and timers Temperature Sensor On-chip accelerated floating-point library 8 programmable I/O (PIO) state machines for custom peripheral support Colour:blue Material:PCB NOte: RP2040-Zero microcontroller PICO development board without pin headers Due to variations between production batches, there may be differences in screen printing or external appearance; however, this does not affect functionality. Additionally, variations in lighting or display settings may result in slight color discrepancies compared to the actual product. Package Contents: 50 x RP2040-Zero Development Board Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
