Tagged: rp2040

The RP2040 has a large on-chip memory, symmetric dual-core processor complex, deterministic bus fabric, and rich peripheral set. It’s augmented with a unique Programmable I/O (PIO) subsystem and provides unrivalled power and flexibility. It has the lowest possible barrier to entry for beginner and hobbyist users with detailed documentation, a polished MicroPython port, and a UF2 bootloader in ROM. RP2040 is a stateless device, with support for cached execute-in-place from external QSPI memory. This design decision allows a choice of an appropriate density of non-volatile storage for applications, and to benefit from the low pricing of commodity Flash parts.
