The Tiniest Raspberry Pi RP2040 Boards – Tiny 2040 & Adafruit QT Py RP2040

The Raspberry Pi Pico officially board for RP2040 MCU has a lot of free space on the PCB. So when third parties made their own board they either added features like camera, display, and sensors as found on like on Arducam Pico4ML board, while others “cut the fat” to the minimum. Some of the tiniest Raspberry Pi RP2040 boards are Pimoroni Tiny 2040 & Adafruit QT Py RP2040, both of which come with the dual-core Cortex-M0+ MCU, a USB-C port, two buttons, some I/O ports, and not much else. Tiny 2040 Pimoroni Tiny 2040 specifications: MCU – Raspberry Pi RP2040 dual-core Cortex-M0+ microcontroller@ up to 133Mhz with 264kB of SRAM Storage – 8MB QSPI flash USB – USB Type-C port for power, data, and programming I/Os – 2x 8-pin castellated and through holes for 12 I/Os pins including 4x analog inputs, SPI, I2C, UART, 5V, 3.3V, and GND Debugging – […]

RK3566 & RK3568 processors to get Linux mainline support soon

Rockchip RK3566 & RK3568 processors were just officially announced at the end of the year, and soon followed with announcements of related such as Core-3568J AI Core system-on-module, some Android 11 TV boxes, Station P2 mini PC, and RK3566/RK3568 development boards. But it did not take long, as RK3566/RK3568 are about the get support for mainline Linux, with engineers from Collabora and Rockchip having recently committed preliminary support for RK356x platforms, notably using Pine64 Quartz64 SBC for testing. The most recent commits target power management, networking, and the PCI host controller. It’s not clear when code will be merged to mainline, but Collabora said “Pine64 Quartz64 SBC out-of-the-box support is right around the corner” in a recent tweet. In any case, it’s good news there’s active development for mainline Linux on the new Rockchip processors, as that means it will be possible to run the latest version of Linux on […]

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

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) […]

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

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, […]

Arduino Core mbed 2.0 supports Raspberry Pi Pico & Arduino Nano RP2040 Connect

Last week, we noted and tried the unofficial Raspberry Pi Pico Arduino Core that works on RP2040 boards, including Raspberry Pi Pico. Everything was super early to set up and the blink sample worked just fine. But Arduino recently tweeted about the Arduino Core mbed 2.0 release that adds for Raspberry Pi RP2040 boards including Arduino Nano RP2040 Connect and Raspberry Pi Pico boards. Arduino first used mbed for their Arduino Nano 33 BLE board as they didn’t have an official Arduino core for the Nordic nRF52840 Cortex-M4 microcontroller, and it appears they’ve done the same for Raspberry Pi RP2040 whose mbed implementation itself relies on the C SDK. Let’s have a try, how hard can it be? We can find the release and changelog on Github with some instructions on the main Github. First, we can clone the repo in the sketchbook directory (See Arduino IDE’s preferences) which in […]

DIY Raspberry Pi Compute Module 4 NAS supports up to four drives

We previously noted it was possible to build a Raspberry Pi CM4 NAS using Wiretrustee carrier board with a built-in Marvell 88SE9215 PCIe to SATA controller and four SATA connectors. But Mebs just created his own Raspberry Pi Compute Module 4 four-bay NAS with his own carrier board equipped with a PCIe socket used to insert a PCIe SATA card, as well as a neat 3D printed enclosure that took 6 days to print. This carrier board design is actually derived from the official Raspberry Pi CM4 IO board with only the interfaces needed for the NAS to make it smaller and fit within the width of a standard 3.5″ hard drive. It was also made as simple as possible because it was Mebs’ first PCB design. This leaves the board with Gigabit Ethernet, one HDMI port, a USB 2.0 port, the PCIe 2.0 socket, as well as some headers […]

GMSL2 camera kit supports 15-meter long cables, up to six cameras with NVIDIA Jetson Xavier AGX

We’ve recently seen it’s possible to use a long cable with the Raspberry Pi camera thanks to THine camera extension kit that works with 20-meter LAN cables using V-by-One HS technology. e-con Systems has now launched a similar solution for NVIDIA Jetson Xavier AGX, one of the most powerful Arm devkits available in 2021, with NileCAM21 Full HD GMSL2 HDR Camera that supports up to 15-meter long cable as well as LFM (LED Flickering Mitigation) technology. NileCAM21 camera features and specifications: Based on OnSemi AR0233 Full HD camera module with S-mount interchangeable lens holder Gigabit Multimedia Serial Link 2 (GMSL2) interface with FAKRA connector Shielded coaxial cable for transmission of power and data over long distances (up to 15m) High Dynamic Range (HDR) with LED Flickering Mitigation (LFM) Supported resolutions and max frame rates for uncompressed UYVY streaming VGA (640 x 480) up to 60 fps qHD (960 x 540) […]

Raspberry Pi Pico Arduino Core released for RP2040 boards

Since Arduino plans to launch its own Raspberry Pi RP2040 based board with Arduino Nano RP2040 Connect, one would have expected software support for the Arduino IDE would have come from the company itself. But apparently, the developer community, or more exactly Earle F. Philhower, III did not feel like waiting. He had previously written ESP8266Audio library for audio file and I2S sound playing routines for ESP8266 & ESP32, and has recently released Raspberry Pi Pico Arduino Core on arduino-pico Github repository. The implementation appears to be already fairly comprehensive with support for digitalWrite/Read, shiftIn/Out, SPI master, analogWrite/PWM, Wire/I2C Master and Slave, analogRead and Pico chip temperature, filesystems like LittleFS and SD/SDFS, I2S audio output, and more. The Raspberry Pi RP2040 programmable IOs are also used to control servos, generate tones, and I2S output. You’ll need the Arduino IDE 1.8.x or the beta version of Arduino IDE 2.0, and add […]
