BreadboardOS firmware for the Raspberry Pi RP2040 features a Linux-like terminal

Cavin McKinley’s BreadboardOS is an open-source firmware platform for the Raspberry Pi RP2040 MCU (for now) built around FreeRTOS and with a feature-packed CLI that reminds me of the Linux terminal.

The terminal implementation is based on a fork of the microshell project with some additional customization. It is organized into POSIX-style folders/files providing a familiar user interface for interacting with the hardware on the MCU.

BreadboardOS running on Raspberry Pi Pico board

BreadboardOS highlights:

FreeRTOS-based
Tools for checking system resources such as ps, top, free, and df commands
Interaction with chip I/O and serial buses from the terminal using commands such as cat and echo, for example, you can print the list of GPIOs with:

Raspberry Pi Zero HAT compatible Quectel BG95-M3 Zero cellular IoT board runs QuecPython MicroPython firmware

Waveshare BG95-M3 Zero is a Raspberry Pi Zero-sized SBC based on Quectel BG95-M3 cellular IoT module with LTE Cat M1 (eMTC), LTE Cat NB2 (NB-IoT), and eGPRS connectivity as well as GNSS. The board supports Raspberry Pi HATs and ships with Quectel’s QuecPython MicroPython firmware for easier programming. We’ve previously covered various SBCs and Raspberry Pi HATs based on Quectel modules for cellular IoT and GNSS connectivity with the likes of Olimex NB-IoT-Devkit (with a BC66 module), S-2Connect Creo evaluation kit, Sixfab 5G Modem HAT, and others. Olimex BC66 board supports Arduino programming, but most of the other boards rely on a host processor. Waveshare’s BG95-M3 Zero is a standalone SBC offering compatibility with Raspberry Pi Zero (p)HATs, and Quectel also developed its own MicroPython firmware called QuecPython that works with several of their modules, including the BG95-M3. BG95-M3 Zero specifications: Cellular IoT Module – Quectel BG95-M3 CPU – Arm […]

AAEON RICO-3568 is a Pico-ITX Plus board powered by a Rockchip RK3568 SoC

AAEON RICO-3568 is a Pico-ITX Plus single board computer powered by a Rockchip RK3568 quad-core Cortex-A55 AI SoC, up to 8GB LPDDR4, 16GB eMMC flash, four display interfaces (HDMI, LVDS, eDP, MIPI DSI), gigabit Ethernet, and various expansion headers for industrial applications. Most have already heard about the Pico-ITX form factor, but it’s the first time I’ve ever come across a Pico-ITX Plus board. It looks like it’s an AAEON-specific “standard” right now, with the Pico-ITX Plus boards (100x80mm) being slightly wider than Pico-ITX SBCs (100x72mm). AAEON RICO-3568 specifications: SoC – Rockchip RK3568 CPU – Quad-core Cortex A55 processor at up to 2.0 GHz GPU – Mali G52 GPU with support for OpenGL ES 1.1/2.0/3.2, OpenCL 2.0, Vulkan 1.1 VPU 4Kp60 H.264, H.265, VP9, 1080p60 MPEG-4/-2/-1, VP8, and VC1 video decoder 1080p60 H.264/H.265 video encoder AI accelerator – 0.8 TOPS NPU System Memory – 2GB, 4GB, and 8GB LPDDR4 Storage […]

Easily build a robot car with the Car Base Board for the STM32F411 “Black Pill” board

The Car Base Board from Applying Microcontroller Solutions is a modular platform for building robot car projects powered by the WeAct Studio Black Pill development board. The Black Pill board is an upgrade to the “Blue Pill 2” board and features the STM32F411CEU6 microcontroller running at 100MHz with 512 KB of flash memory, 128 KB SRAM, and a USB Type-C port for power and programming. The Care Base Board printed circuit board is a base controller that takes hardware expansions such as wireless modules, servos, and sensors to monitor and control a robot car. The onboard headers provide a straightforward way to wire these connections and help prevent a tangled mess (rat’s nest) of wires. The PCB’s design makes it easy to use widely-available, “generic” devices and boards in development and to power all of them with batteries. It also allows the developer to select their favorite wireless communication device. […]

MemryX MX3 edge AI accelerator delivers up to 5 TOPS, is offered in die, package, and M.2 and mPCIe modules

Jean-Luc noted the MemryX MX3 edge AI accelerator module while covering the DeGirum ORCA M.2 and USB Edge AI accelerators last month, so today, we’ll have a look at this AI chip and corresponding modules that run computer vision neural networks using common frameworks such as TensorFlow, TensorFlow Lite, ONNX, PyTorch, and Keras. MemryX MX3 Specifications MemryX hasn’t disclosed much performance stats about this chip. All we know is it offers more than 5 TFLOPs. The listed specifications include: Bfloat16 activations Batch = 1 Weights: 4, 8, and 16-bit ~10M parameters stored on-die Host interfaces – PCIe Gen 3 I/O and/or USB 2.0/3.x Power consumption – ~1.0W 1-click compilation for the MX-SDK when mapping neural networks that have multiple layers Under the hood, the MX3 features MemryX Compute Engines (MCE) which are tightly coupled with at-memory computing. This design creates a native, proprietary dataflow architecture that utilizes up to 70% […]

52Pi W01 U2500 HAT adds 2.5GbE and NVMe SSD support to Raspberry Pi 5 SBC

Designed specifically for the Raspberry Pi 5 SBC, the 52Pi W01 U2500 HAT offers support for M.2 M-key NVMe SSDs (2230, 2242, 2260, and 2280) along with a 2.5GbE (2.5 Gbps Ethernet port) using a Realtek RTL8156BG chipset. The most interesting thing about this board is its connectivity – the M.2 SSD is driven directly by the Raspberry Pi’s PCIe port that supports Gen2 & Gen3 standards. However, the 2.5Gbps Ethernet port requires a connection to one of the Pi’s USB ports using a specialized USB-to-USB adapter included by 52Pi. Previously, we have seen 52Pi come up with very innovative and interesting HATs for Raspberry Pi including 52Pi P02 PCIe expansion board, 52Pi NVdigi Expansion Board, 52Pi CM4 Router Board, and many other products. If you want to try something new with your Raspberry Pi, feel free to check those out. 52Pi W01 U2500 2.5Gbps Ethernet + NVMe HAT specifications: […]

Blaustahl USB storage device features 8KB FRAM with up to 200 years of data retention

Machdyne’s Blaustahl is a USB storage device equipped with a Raspberry Pi RP2040 MCU and 8KB of FRAM with a potential lifespan of over 200 years and designed for long-term storage of text up to about 8,000 characters. FRAM (Ferroelectric RAM) has been around for years delivering ultra-low power consumption, faster writes, and ultra-long write endurance (one million billion read/write cycles) compared to EEPROM or NOR flash, but the cost is quite higher and it’s mostly used in applications that require ultra-low power consumption and non-volatile storage write capabilities such as data logging, sensor networks, batteryless applications. The Blaustahl storage device and USB text editor is one of those. Blaustahl speciications: Microcontroller – Raspberry Pi RP2040 dual-core Cortex-M0 processor at 133MHz and 264kB RAM. Storage 4MB (32Mbit) NOR flash for firmware 8KB (64Kbit) FRAM (Fujitsu MB85RS64) Lifespan – 95 years @ +55°C, over 200 years @ +35°C Endurance – 10^12 […]

SparkFun M7E Hecto is a simultaneous RFID Reader with USB-C connectivity and a range of up to 5m

SparkFun has announced the M7E Hecto, a ‘simultaneous’ RFID reader in a compact form factor and high-performance capabilities. The RFID reader is powered by Jadak’s Hecto module (M7E-HECTO) from the ThingMagic series which offers a wide RF output range from 0 dBm to +27 dBm and reads up to 300 tags/second. SparkFun M7E Hecto builds on the much older M6E Nano RFID reader, adding a USB-C port, increasing the read rate from 150 tags/second, and reducing power consumption. It supports an external antenna (sold separately) which extends the scanning distance up to 16 ft (4.8m) from the 1 to 2 ft (0.3m – 0.6m) range supported by the onboard antenna. It does come with a warning to ensure that personnel are not directly in the radiation beam of the antenna while they are within 21cm of the antenna (to adhere to FCC limits for long-term exposure to RF emissions). The […]
