Embedded and hobbyist electronics specialist DFRobot has added a brand new mannequin to its Beetle vary of compact improvement boards, constructing on its earlier Beetle RP2040 with a mannequin based mostly on Raspberry Pi’s second-generation in-house microcontroller: the Beetle RP2350.
“The Beetle RP2350 is a coin-sized, high-performance improvement board powered by [the] Raspberry Pi RP2350 microcontroller,” the corporate writes of its newest improvement board. “It is good for space-constrained purposes like wearables, good dwelling units, and industrial IoT [Internet of Things]. With built-in lithium battery administration, 11 accessible IOs [Inputs/Outputs], and assist for C/C++, MicroPython, and Arduino, it combines portability, effectivity, and ease of use—making it the last word resolution for compact, power-efficient designs.”

On the coronary heart of the Beetle RP2350, delivered to our consideration by Linux Gizmos, is strictly what its title implies: a Raspberry Pi RP2350, the corporate’s second-generation successor to the favored RP2040 microcontroller. That includes an uncommon dual-architecture design, this contains two Arm Cortex-M33 cores alongside two free and open-source Hazard3 RISC-V cores, all operating at as much as 150MHz, and permits the customers to choose any two to be energetic at any given time. There’s 520kB of static RAM (SRAM), with DFRobot including 2MB of on-board flash for program storage.
Like its predecessor the Beetle RP2040, launched three years in the past, the Beetle RP2350 is designed round a small footprint of simply 25×20.5mm (round 0.98×0.81″), although ditches the bizarre large-format solder pads for extra conventional unpopulated 0.1″-spaced breadboard-friendly castellated general-purpose enter/output (GPIO) pins introduced out at both aspect. There’s an on-board charging module for an choice lithium battery, USB Sort-C connectivity for energy and knowledge, and bodily boot-mode and reset switches.
DFRobot has put the Beetle RP2350 up on the market on its retailer at simply $4.90, the identical worth as its earlier Espressif ESP32-C6-based Beetle and two {dollars} lower than the unique Beetle RP2040.s
