Perf-V Beetle board features GAP8 multi-core RISC-V AI MCU

Perf-V Beetle board

GreenWaves Technologies introduced the GAP8 low-power RISC-V IoT processor optimized for artificial intelligence applications in 2018. The multi-core (8+1) RISC-V processor is especially suitable for image and audio algorithms including convolutional neural network (CNN) inference. The same year, the company launched the GAPUINO development kit that sold and (still sells) for $229 with QVGA camera and a multisensor board with four microphones, an STMicro VL53 Time of flight sensor, an IR sensor, a pressure sensor, a light sensor, a temperature & humidity sensor, and a 6-axis accelerometer/gyroscope. But there’s now a much more affordable solution to evaluate GAP8 multi-core RISC-V MCU with PerfXLab Perf-V Beetle board. Perf-V Beetle board specifications: MCU – GAP8 IoT Application Processor with 8x RISC-V compute cores, 1x RISC-V fabric controller core delivering up to 200 MOPS at 1mW and >8 GOPS at a few tens of mW System Memory – 64 Mbit SPI SRAM (LY68L6400SLIT) Storage – 128 Mbit SPI flash  (WS25Q128FVSIG) Audio – 4x […]

A first look at Allwinner D1 Linux RISC-V SBC and Processor

Allwinner D1 RISC-V SBC

Last year, we reported that Allwinner was working on an Alibaba XuanTie C906 based RISC-V processor that would be found in low-cost Linux capable single board computers selling for as low as $12. The good news is that we won’t have to wait much longer as Allwinner D1 RISC-V processor is slated for an announcement next week, and a business card-sized SBC, also made by Allwinner, will become available in May. Some of the information is already available to developers in China, and CNX Software managed to obtain information about the Linux RISC-V SBC and Allwinner D1 processor. Allwinner D1 development board Let’s check out the board first which comes with the following specifications: SoC – Allwinner D1 single-core XuanTie C906 64-bit RISC-V processor @ 1.0 GHz with HiFi4 DSP, G2D 2D graphics accelerators Memory – 1GB DDR3 memory Storage – 256MB SPI NAND flash, MicroSD card slot Video Output – HDMI 1.4 port up to 4Kp30, MIPI DSI & […]

Arducam Pico4ML Board – TinyML on Raspberry Pi RP2040 with QVGA Camera & Display

Arducam Pico4ML

A few months ago, ArduCAM demonstrated person detection on Raspberry Pi Pico with Arducam camera using TensorFlow Lite, and later we noted more work was being performed to bring machine learning to RP2040 platforms, notably with the development of Arducam Pico4ML board with a built-in camera and display. At the time, i..e last month, all we had were some renders of the board, but now Arducam Pico4ML pre-orders have launched for $49.99 on UCTRONICS and Tindie stores. Shipping is scheduled to start at the end of the month, so let’s have a closer look. Arducam Pico4ML TinyML devkit specifications: Microcontroller – Raspberry Pi RP2040 dual-core Cortex-M0+ MCU with 264 KB of embedded SRAM Storage – 2MB SPI flash Display – 0.96-inch LCD SPI Display (ST7735) with 160 x 80 resolution Camera – HiMax HM01B0 QVGA camera (320×240 @ 60fps) Audio – Built-in microphone Sensor – IDK ICM-20948 9-axis IMU (gyroscope, accelerometer, compass) Expansion – 2x 20-pin headers that follows Raspberry […]

Olimex RP2040-PICO-PC “computer” to feature RP2040-Py Raspberry Pi Pico compatible module

RP2040-PICO-PC board

We previously wrote it was possible to create a Raspberry Pi RP2040 board with HDMI using DVI and programmable IOs to output video up to 640×480 at 60 Hz with the microcontroller’s Cortex-M0+ cores clocked at 252 MHz. At the time, we also noted Olimex was working on such a board with RP2040-PICO-PC designed to create a small Raspberry Pi RP2040 computer with HDMI/DVI video output.  The Bulgarian company has now manufactured the first prototype, but due to supply issues with the Raspberry Pi Pico board, they also designed their own RP2040-PICO module since they’ve got a reel of Raspberry Pi RP2040 microcontrollers. RP2040-PICO-PC small computer board Specifications: Support for Raspberry Pi Pico board Storage – MicroSD card Video Output – HDMI port with DVI signal (note no audio through this interface) Audio output – 3.5mm audio jack Expansion UEXT connector with UART, SPI, I2C, 3.3V, and GND to attach external modules or sensors from Olimex Grove compatible 4-pin JST2.0 […]

simpleRTK2B-SBC packs 3 u‑blox ZED-F9P RTK GNSS receivers for centimeter-level GPS positioning

simpleRTK2B-SBC RTK GNSS board

Real-time Kinematic (RTK) relative positioning technique allows for 1-3cm positioning accuracy with data derived from satellite-based positioning systems such as GPS, BeiDou, GLONASS, Galileo, and NavIC. We’ve previously covered Skytraq PX1122R RTK GNSS module as well as SBG Systems Ellipse-D industrial-grade inertial navigation system featuring the technology, and now Spain-based ArduSimple has announced the simpleRTK2B-SBC single board computer that aims to “simplify the development of centimeter-level positioning solutions supporting real-time kinematics (RTK)” via up to three u‑blox ZED-F9P RTK GNSS receivers. simpleRTK2B-SBC board features & specifications: MCU – STMicro STM32F7 Cortex-M7 microcontroller GNSS Positioning 184-channel u-blox ZED-F9P engine Configuration options 2x ZED-F9P for position + heading 3x ZED-F9P for position + full attitude (roll, pitch, yaw) Navigation rate up to 20Hz Position accuracy down to 1 centimeter GPS: L1 & L2;  GLONASS: L1OF & L2OF;  Galileo: E1 & E5b;  BeiDou: B2I & B2I; QZSS and SBAS Up to 4 integrated SMA for various RF options Configuration flexibility – standalone, standalone […]

Minima is a tiny Arduino Zero compatible module with SAMD21 MCU (Crowdfunding)

Minima Arduino Zero Module

We’ve covered a fair amount of compact Arduino Zero compatible boards based on SAMD21 Cortex-M0+ microcontroller over the years including Exen Proto, Wemos D1 SAMD21, or Seeeduino XIAO with the latter being the smallest of them all at just 23.5 x 17.5 mm. All those boards come with a USB port (Micro USB or USB-C) by default that makes it easy to work with, but may not be ideal to integrate into projects or final products. That may be why Hamish Morley designed the Minima Arduino Zero compatible module with a size even smaller than the XIAO board at 19.8 x 16.6 mm, and the USB interface exposed through 4 pads instead of a connector. Minima specifications: Microchip SAMD21G18A 32-bit Arm Cortex-M0+ microcontroller @ 48 MHz with 256KB of flash storage, and 32KB of SRAM Expansion – 24x castellated pads (2.54mm pitch) with 18 GPIO pins, including 5x analogue capable, plys PWM, SPI, I2C, UART Misc – Reset button, Tx/Rx […]

Board::mini development tools offer a complete Vehicle-Hacking Platform (Crowdfunding)

board::mini base CAN bus automotive development board

If you are looking to connect to a vehicle’s CAN bus, then the newly launched open-source board::mini development tools include a board and expansion boards that will aid your application. BMC labs have introduced a development board based on the STM32 MCU and supporting expansion boards to increase the capabilities of the baseboard via a crowdfunding project.  As mentioned earlier, the board:mini base development board features an STM32 MCU at its heart and comes with a CAN transceiver. For those who do not know what a CAN transceiver is, it just transmits and detects data on the CAN bus. The board:mini project also includes three expansion boards designed to fit on top of the base development board.  The bmc::board project was born to produce development tools appropriate for both field- and industrial-prototyping work. These boards were not designed to sit on a workbench. We ourselves have a habit of strapping them to vehicles, but…the qualities that make them suitable for […]

Top 5 most powerful Arm SBC’s & Devkits in 2021

Most Powerful Arm SBCs development kit 2021

While companies like Hardkernel, Raspberry Pi, Orange Pi, and FriendlyArm offers affordable, great little Arm Linux development boards that are suitable for many projects, in some cases, your requirements may lead you to spend a bit more for either extra CPU power, more memory, AI processing power, faster I/Os and so on. That’s why I did a list of the most powerful Arm single board computers in late 2017, but with over three years passed since then an update is warranted. The boards from the list must be easily purchasable from individuals (with the cash to spare) or small companies, so we’ll exclude hard-to-source hardware, as well as Arm server boards like Ampere eMAG motherboard, that do not really qualify as single board computers. Snapdragon 888 Mobile Hardware Development Kit While there are plenty of Cortex-A72/A73 development boards around, it’s much hardware to find one with more recent Cortex-X1 or Cortex-A78 cores, and Lantronix Snapdragon 888 Mobile Hardware Development Kit […]
