Raspberry Pi has introduced a significant milestone for anybody seeking to transcend off-the-shelf microcontroller boards for his or her subsequent mission: the overall availability of its second-generation RP2350 microcontroller from its community of world resellers.
“Final summer season we unveiled RP2350, our second-generation microcontroller platform, constructing on the success of RP2040, and designed to ship even greater efficiency at an identical reasonably priced value,” says Raspberry Pi’s Eben Upton. “At present, we’re delighted to announce that RP2350 is now available for purchase from our worldwide community of Raspberry Pi Accepted Resellers. Our world community of Raspberry Pi Accepted Resellers ensures you may entry RP2350 rapidly and affordably, regardless of the place you might be, with quick native transport and dependable customer support.”
The RP2350 launched again in August final 12 months, on board the corporate’s Raspberry Pi Pico 2 microcontroller improvement board — although, technically talking, this was the second gadget to characteristic the chip, after a shock debut on the badge for the DEFCON 32 hackers’ convention. The place the unique RP2050, the corporate’s first in-house microcontroller design, had two Arm Cortex-M0+ cores, the RP2350 options two extra highly effective Arm Cortex-M33 cores plus the choice to make use of a pair of free and open-source RISC-V-based Hazard3 cores as an alternative. There’s 520kB of RAM, enlarged Programmable Enter/Output (PIO) blocks, and a brand new Excessive-Velocity Transmission (HSTX) peripheral that may drive a DVI-compatible show with out tying up the CPU or PIO.
Whereas the RP2350, and its bigger siblings the RP2350A and RP2350B, have been accessible at quantity direct from Raspberry Pi, permitting third-party firms to launch their very own boards, they haven’t been accessible to people in low minimal order portions — till now. The RP2040 is priced at $0.70 per unit in a 3,400-unit reel, $0.80 per unit in a 500-unit reel, or $1 in single-unit portions; when you’d quite choose up the bigger RP2350, that is $0.80 every in 3,400 portions, $0.90 in 500 portions, or $1.10 for only one chip; and the RP2350B, with the biggest general-purpose enter/output (GPIO) provision of any mannequin, is priced at $0.90 per unit in 2,500 portions, $1 in 500 portions, and $1.20 for a single chip.

“For smaller-footprint purposes, our RP2354A and RP2354B variants — that includes 2MB of stacked flash reminiscence — are within the remaining levels of improvement and testing with early-access companions,” Upton provides of the corporate’s plans for follow-up designs, referring to the corporate’s plans to launch the primary RP-family chips with built-in flash storage. “We’ll quickly be ramping to mass manufacturing, and plan to make these variants accessible via our Accepted Reseller companions later this 12 months.”
