Romu – A Tiny Raspberry Pi RP2354A board for USB application development (Crowdfunding)

Bitmerse Romu is a tiny (15.5 x 12 mm), almost minimal Raspberry Pi RP2354A USB board with a USB 2.0 interface on one side of the PCB, and the dual Cortex-M33/RISC-V MCU on the other side, connected to a few debugging/programming pads, buttons, and an RGB LED. It doesn’t come with any GPIO, and it’s mostly designed for USB applications such as a security key for passwordless login, a USB MIDI controller, a macro pad, or a custom HID device. You can plug it directly into a spare USB Type-A port of your computer/host without any cables, breadboard, or adapters required. Romu specifications: SoC – Raspberry Pi RP2354A CPU Dual-core Arm Cortex-M33 @ 150 MHz with Arm Trustzone, Secure boot Dual-core 32-bit RISC-V Hazard3 @ 150 MHz (3-stage in-order pipeline; RV32IMAC with Zba, Zbb, Zbs, Zbkb, Zcb, Zcmp, and Zicsr extensions) Up to two cores can be used at a time, either 2x […]

Facebook releases Muse Gadgets SDK for ESP32 and Raspberry Pi/Linux-based devices

Meta, Facebook’s parent company, has released the open-source Muse Gadgets SDK, designed to work with ESP32 boards or Linux-based SBCs like a Raspberry Pi. This requires some explanation… I’ve been on holiday for a while, so I’m not up to date on everything, but apparently Meta released Muse on September 6, yet another personal AI agent… Earlier this month, Nat Friedman, head of product at Meta Superintelligence Labs, shared an X post about the Muse Gadgets “side project” that aims to make ESP32 and Linux devices work with Muse, basically enabling hardware AI monitors and Physical AI with Muse. The Muse Gadgets SDK has been released on GitHub under an Apache 2.0 license (for most of the code) with two main directories: ESP32 Device SDK – It can show images, supports audio input and output, and can interface with sensors, actuators, buttons, etc… Linux Device SDK – Works with Raspberry […]

Q8botOne – A palm-sized open-source quadruped robot with ESP32-C3, DYNAMIXEL smart actuators (Crowdfunding)

Q8botOne A Serious Quadruped That Fits in Your Hand

ZeroWire Robotics Q8botOne is an open-source, palm-sized quadruped robot built around an ESP32-C3 MCU and ROBOTIS DYNAMIXEL smart actuators. Designed with a unique wire-free architecture, the robot integrates all components onto a central printed circuit board also used as the structural chassis. The robot is roughly the size of a smartphone and can jog, jump, and carry up to twice its 250-gram weight. The main PCB uses a dedicated 6V/16A step-down converter for motor power and includes a battery management system for two 14500 Li-ion cells. For control, the kit includes a separate ESP32-C3 controller PCB with an Adafruit Mini I2C Gamepad. Q8botOne specifications: Wireless module – Espressif Systems ESP32-C3-MINI-1-N4 module with: ESP32-C3 (ESP32-C3FN4) SoC CPU – 32-bit RISC-V single-core processor up to 160 MHz Memory – 400 KB SRAM (16 KB for cache), 8 KB SRAM in RTC Storage – 4 MB embedded flash, 384 KB ROM Connectivity – […]

DSPi firmware turns Raspberry Pi RP2040/RP2350 into a USB sound card with an onboard DSP engine

Raspberry Pi Pico configuration in DSPi Console

DSPi is a full-featured audio DSP firmware for the Raspberry Pi Pico, Pico 2, and other Raspberry Pi RP2040/RP2350 boards, which turns them into a USB sound card with an integrated DSP. It allows users to make use of essential tools like room correction, active crossovers, parametric EQ, time alignment, and more, and essentially works as a regular sound card on your computer. DSPi firmware’s capabilities: Dual-Core DSP – EQ processing is split across both cores on both RP2040 and RP2350. USB Audio Interface – Supports 16-bit and 24-bit PCM input at 44.1, 48, and 96 kHz, working on macOS, Windows, Linux, and iOS. S/PDIF Input – 24-bit PCM stereo audio at 44.1 or 48kHz. 24-bit S/PDIF or I2S Outputs – Up to 4x independent stereo output slots (8x channels on RP2350, 4x channels on RP2040). Subwoofer Output – Dedicated mono PDM output channel with a high-performance 2nd-order delta-sigma modulator, […]

Geekworm UPS Scap 5V5A – A supercapacitor UPS HAT for Raspberry Pi 5

Geekworm’s Raspberry Pi 5 supercapacitor UPS HAT

Geekworm, in collaboration with Mcuzone, has launched the UPS Scap 5V5A, a new supercapacitor UPS HAT for the Raspberry Pi 5 designed to keep the Raspberry Pi running long enough (a few seconds to a few minutes) to save data and shut down safely, rather than provide hours of backup power. Available in 100F, 60F, and 22F versions, the HAT has a built-in PD chip that negotiates a true 5V/5A output. This gives the Raspberry Pi 5 enough power to run properly without triggering the low-voltage warnings that can happen with some power supplies. The module connects to the Raspberry Pi 5 through pogo pins to detect power loss and supports I2C for checking voltage and current in real time. It also features dual independent power inputs, so you can power it with either a wide-voltage DC barrel jack or a standard USB-C PD charger. Geekworm UPS Scap 5V5A supercapacitor […]

$30 Raspberry Pi Smart Display Module for CM5 targets digital signage displays and kiosks

Raspberry Pi Smart Display Module is a CM5 carrier board compatible with the Intel Smart Display Module (SDM) specification, more specifically the SDM-L form factor (as opposed to the smaller SDM-S option). The Intel SDM standard has been around for years, and we first wrote it in 2018, covering the Axiomtek SDM300s (SDM-S) module. These cards are designed to be plugged into compatible digital signage displays, kiosks, point-of-sale systems, and so on. They feature a standard 98-pin PCIe edge connector with USB 3.0, HDMI 1.4/2.0, I2C/UART/SPI signalling, as well as Ethernet, HDMI, USB ports, and an M.2 expansion socket. Raspberry Pi Smart Display Module specifications: Compatible with Raspberry Pi Compute Module 5 Video Output – Full-size HDMI 2.0 port Camera – 22-way MIPI DSI/CSI-2 connector (internal) Networking Gigabit Ethernet RJ45 port WiFi 5 and Bluetooth 5.2 (on CM5) with U.FL antenna USB USB 3.0 Type-A port USB 2.0 Type-C port for programming […]

Walnut Pi CM2 – A cheaper Raspberry Pi CM5 alternative based on Allwinner T527 octa-core SoC

Walnut Pi CM2 is a low-cost Raspberry Pi CM5-compatible Compute Module powered by an Allwinner T527 octa-core Cortex-A55 processor paired with up to 4GB LPDDR4 RAM, 16GB eMMC flash, and an optional wireless module. It’s basically the company’s Walnut Pi 2B credit card-sized SBC in Pi Compute Module form factor, exposing I/Os via two 100-pin high-density connectors. Besides the price, benefits include a WiFi 6 and Bluetooth 5.0 module, a Gigabit Ethernet PHY on the module, and a built-in 2 TOPS NPU in the T527 SoC. Downsides are that the Allwinner T527 is not quite as powerful as the Broadcom BCM2712 (4x Cortex-A76 cores) found in the CM5, and as with other such “Raspberry Pi CM5-compatible” modules, it’s only partially electrically compatible. Walnut Pi CM2 specifications: SoC – Allwinner T527 CPU Octa-core Arm Cortex-A55 processor with four cores @ 1.80 GHz and four cores @ 1.42GHz E906 RISC-V core up […]
