RP2350 Boards
SparkFun Pro Micro - RP2350
The SparkFun RP2350 Pro Micro provides a powerful development platform in SparkFun's compact Pro Micro form factor, built around the RP2350 from the Raspberry Pi Foundation. It includes a USB-C connector, Qwiic connector, WS2812B addressable RGB LED, Boot and Reset buttons, resettable PTC fuse, and PTH and castellated solder pads.
The RP3250 is a unique dual-core microcontroller with two ARM® Cortex® M33 processors and two Hazard3 RISC-V processors, all running at up to 150 MHz! The Pro Micro also includes two expanded memory options: 16MB of external Flash and 8MB PSRAM connected to the RP2350's QSPI controller. The RP2350 Pro Micro works with C/C++ using the Pico SDK and MicroPython development environments.
Raspberry Pi Pico 2
The Raspberry Pi Pico 2 built on the RP2350: a new high-performance, secure microcontroller also from Raspberry Pi. The RP2350 features a higher core clock speed, double the on-chip SRAM, double the on-board flash memory, more powerful Arm cores, optional RISC-V cores, new security features, and upgraded interfacing capabilities.
The RP2350 provides a comprehensive security architecture, built around Arm TrustZone for Cortex-M, and incorporating signed boot, 8KB of antifuse OTP for key storage, SHA-256 acceleration, a hardware TRNG, and fast glitch detectors.
