Raspberry Pi 4 gets Vulkan 1.2 conformance, Android Vulkan support

Iglia has done more work on the graphics driver for the VideoCore VI GPU found in Raspberry Pi 4 and other Broadcom BCM2711-based hardware with Vulkan 1.2 conformance, and Roman Stratiienko added Vulkan 3D graphics acceleration to Android, or more exactly LineageOS. Raspberry Pi and Iglia have been collaborating together since the launch of the Raspberry Pi 4 SBC to develop a Khronos conformant Mesa 3D graphics driver for the board, and that’s a long-term project that’s been going on for over two years, and not quite finished yet. Here’s a non-exhaustive timeline of the project so far: February 2020 – Raspberry Pi 4 V3DV driver gets OpenGL ES 3.1 conformance, work on Vulkan starts with the basic triangle demo showcased June 2020 – Vulkan driver source code released with many demos working on Raspberry Pi 4 October 2020 – Iglia gives a project update status presentation for Raspberry Pi […]

52Pi CM4 Router Board also features HDMI, 40-pin Raspberry Pi HAT header, and OLED display

We’ve already seen compact Raspberry Pi CM4 based router boards with two Ethernet ports from DFRobots, Seeed Studio, and MCUZone. 52Pi CM4 Router Board expands on the same principle but also offers HDMI output, a 40-pin GPIO header for Raspberry Pi HAT expansion boards, and a small OLED information display. The board also includes two Gigabit Ethernet, plus the WiFi and Bluetooth connectivity from the Raspberry Pi CM4, and the extra features make the board larger (146x50mm) than competitors. But that makes the platform that much more flexibly, and can be used as a gateways for all sorts of projects thanks to the wide range of Raspberry Pi HAT available in the market. 52Pi CM4 Router Board (EP-0146) specifications: Compatible with Raspberry Pi Compute Module 4 series Storage – MicroSD card slot (only used with Raspberry Pi CM4 Lite) Video Output – HDMI 2.0 port up to 4Kp60 Display – […]

EncroPi – A Raspberry Pi RP2040 USB key to read, encrypt & store data (Crowdfunding)

SB Components’ EncroPi is a USB key based on the Raspberry Pi RP2040 microcontroller that can be used to log data, encrypt data, or as a secure key, and it also features a DS3231 real-time clock with a backup battery to store the data and time. The USB key also comes with a small 1.14-inch color display to display information such as time and date, and should be programmable like the Raspberry Pi Pico with MicroPython or C/C++. All photo shows a USB Type-A port, but based on user feedback the company will also make a USB Type-C version. EncroPi specifications: MCU – Raspberry Pi RP2040 dual-core Cortex-M0+ microcontroller @ 133 MHz with 264KB SRAM Storage – QSPI flash, MicroSD card slot Display – 1.14-inch color LCD with 240 x 135 resolution USB – 1x USB 2.0 Type-A or Type-C port (should it be USB 1.1 instead?) Misc – Boot […]

Review of SunFounder TS7-Pro 7-inch touchscreen display for Raspberry Pi 4

Unboxing SunFounder TS7-Pro touchscreen display SunFounder TS7-Pro is a 7-inch touchscreen display designed for Raspberry Pi 4 board and the company sent us one review sample for evaluation. SunFounder has a wide range of Raspberry Pi and Arduino accessories designed for makers, and the TS7-Pro 7 is their latest offering that’s optimized to work with Raspberry Pi 4 and Raspberry Pi 3. Adding a touchscreen display to a Raspberry Pi may be a bit messy with the display or other accessories such as cameras and/or 2.5-inch drive spread on the table, but the TS7-Pro display simplifies all that with a neater assembly. Let’s start the review with an unboxing The package is compact and the display is well-protected with polyethylene foam to reduce the risk of damage during transport. Accessories such as cables, screws and nuts, adapters, an acrylic enclosure, and a screwdriver are also included in the package. Here’s […]

Compact3566 – A Rockchip RK3566 SBC that closely follows Raspberry Pi 3 form factor

We’ve very recently written about Geniatech XPI-3566 SBC powered by Rockchip RK3566 CPU that somewhat follows the Raspberry Pi 3 Model B form factor. Boardcon Compact3566 offers similar features, but it appears to keep exactly the same port assignment as the Raspberry Pi SBC, so it should be compatible with more accessories. The Compact3566 SBC ships with up to 8GB LPDDR4 and 128GB eMMC flash, features Gigabit Ethernet & WiFi 5, four USB 3.0/2.0 ports, HDMI 2.0 output, MIPI DSI and CSI interfaces, the 40-pin GPIO header, as well as extra built-in features such as an M.2 socket for storage, RTC with battery, and a built-in microphone. Compact3566 specifications: SoC – Rockchip RK3566 quad-core Arm Cortex-A55 @ up to 1.8 GHz with ARM Mali-G52 2EE GPU with support for OpenGL ES 1.1/2.0/3.2. OpenCL 2.0. Vulkan 1.1, 0.8 TOPS NPU System Memory – 2GB, 4GB, or 8GB LPDDR4/LPDDR4X Storage 8GB, 16GB, […]

Theengs open-source tools to decode BLE sensors work on ESP32, Raspberry Pi, Android phone, etc…

Theengs is a manufacturer agnostic open-source set of tools to decode BLE sensors and integrate those into smart home and IoT solutions such as Home Assistant with notably support for autodiscovery to automatically create the sensor. Theengs can be installed on various hardware from ESP32 to an Android phone or a Raspberry Pi SBC, and the solution currently supports close to forty BLE sensors from various companies including Xiaomi, Honeywell, and RuuviTag. There are six components: The Theengs Decoder library developed in C++ for portability and translating data from sensors into human-readable data using the JSON format. The Python-based Theengs Gateway acting as a BLE to MQTT bridge for Home Assistant, OpenHAB, and NodeRED integration. It relies on the Theengs Decoder library and publishes the sensors broadcasted BLE information to an MQTT broker. The OpenMQTTGateway is also BLE to MQTT bridge, but instead of targetting Linux-capable hardware like Raspberry […]

CrowPi L Raspberry Pi 4 laptop review – Part 1: Unboxing and teardown

CrowPi L Raspberry Pi Education Laptop Review

Elecrow CrowPi L is an 11.6-inch laptop shell based on Raspberry Pi 4 designed for STEM education with optional electronics modules and tutorials. That’s an evolution of the CrowPi 2 laptop I reviewed in 2020 with a thinner design and more flexible since the electronics modules are optional, so it can serve the market of people just wanting a Raspberry Pi 4 laptop. The company has sent me a full “CrowPi L Advanced Kit” for review with the CrowPi L laptop fitted with a Raspberry Pi 4, as well as the Crowtail Starter Kit for Raspberry Pi. CrowPi L Advanced Kit Unboxing Let’s check out the laptop package first. Since in this design, the laptop comes with a battery, and mine already had a Raspberry Pi 4 installed, I could just turn it on immediately. Accessories include a wireless mouse, a 12V/2A power supply (with USB Type-C plug… this should […]
