  "textContent": "While searching Tindie for a new project, I found a new Raspberry Pi RP2350B-based development board called “Bells&Whistles,” which is interesting because it also features an onboard RP2040-based debugger running Picoprobe firmware, removing the need for a separate debug probe. Other than that, it has an HDMI output, a MicroSD card slot for storage, an optional 8 MB of PSRAM, and since it uses the Raspberry Pi RP2350B variant, it supports up to 46 GPIO pins. The board also features two USB Type-C ports, one for the RP2350B and the other for the RP2040 debugger, and is especially useful for clutter-free rapid prototyping and development workflows. RP2350B bells&whistles board specifications: SoC – Raspberry Pi RP2350B CPU Dual-core Arm Cortex-M33 @ 150 MHz with Arm TrustZone Dual-core RISC-V Hazard3 @ 150 MHz Only two cores can be used at any given time Memory – 520 KB on-chip SRAM Package – QFN-80 Memory – [...]\n\nThe post RP2350B bells&whistles development board features on-board RP2040 debugger, HDMI, and microSD card slot appeared first on CNX Software - Embedded Systems News.",
