RP2040 development board with pre-soldered headers

This LORDWORLD board carries the RP2040 microcontroller designed by Raspberry Pi in the United Kingdom. It provides a dual-core Arm Cortex M0+ processor with a flexible clock running up to 133 MHz. The board includes 264KB of SRAM and 2MB of on-board Flash memory. Pre-soldered headers and an onboard 3-pin debug connector are fitted for immediate use.

Dual-core Arm Cortex M0+ at 133 MHz

The processor is the specification that determines whether this board suits your application. Two Cortex M0+ cores share the 133 MHz maximum clock and on-chip accelerated floating-point libraries. Code runs from the 264KB SRAM while the 2MB Flash stores firmware. USB 1.1 device and host support enables drag-and-drop programming over mass storage without extra tools.

Low-power modes for sustained operation

Sleep and dormant modes reduce current draw when the workload allows idle time. The flexible clock can scale below 133 MHz to match throughput needs without forcing peak frequency continuously. Castellated edges permit direct soldering to a carrier board for compact, permanent integration. This combination keeps the device functional during long deployments rather than short bench tests.

Perguntas sobre este artigo

What does the 133 MHz clock speed mean when the board is running my code?

The dual-core Arm Cortex M0+ processor can execute up to 133 million cycles per second, giving fast deterministic response for real-time tasks and enough headroom for floating-point math using the on-chip accelerated libraries.

What does the USB 1.1 interface actually limit in daily use?

USB 1.1 provides device and host support for drag-and-drop programming over mass storage and serial debug, but its low-speed and full-speed signalling caps bulk throughput, so large data streams need a different link.

How do the castellated edges and pre-soldered headers affect mounting options?

Castellated pads let you solder the module directly onto a carrier board for a low-profile permanent fit, while the pre-soldered through-hole headers allow quick breadboard or socket use without extra assembly.
