Raspberry Pi 4 vs Pi 3 – What are the differences?

So now that the Raspberry Pi 4 model B has just been launched, it may be worth checking out the differences against the previous latest single board computer from the Raspberry Pi foundation, namely Raspberry Pi 3 model B+. Let’s get straight to the Raspberry Pi 4 vs Pi 3 B+ comparison table. Features/Specs Raspberry Pi 4B Raspberry Pi 3 B+ Release date 24th June 2019 14th March 2018 SoC Broadcom BCM2711 quad-core Cortex-A72 @ 1.5 GHz Broadcom BCM2837B0 quad-core Cortex-A53 @ 1.4 GHz GPU VideoCore VI with OpenGL ES 1.1, 2.0, 3.0 VideoCore IV with OpenGL ES 1.1, 2.0 Video Decode H.265 4Kp60, H.264 1080p60 H.264 & MPEG-4 1080p30 Video Encode H.264 1080p30 Memory 1GB, 2GB, or 4GB LPDDR4 1GB LPDDR2 Storage microSD card Video & Audio Output 2x micro HDMI ports up to 4Kp60 3.5mm AV port (composite + audio) MIPI DSI connector 1x HDMI 1.4 port up […]

Raspberry Pi 4 Features Broadcom BCM2711 Processor, Up to 4GB RAM

Long expected, the Raspberry Pi 4 model B has finally launched, and it should not disappoint with a much more powerful Broadcom BCM2711 quad-core Cortex-A72 processor clocked at up to 1.5 GHz, 1 to 4GB LPDDR4, 4K H.265 video decoding and output support, a proper Gigabit Ethernet port, as well as USB 3.0 and 2.0 ports. Raspberry Pi 4 comes with all those extra features, but the form factor remains the same, and importantly the price is still $35 for the version with 1GB RAM, making Raspberry Pi alternatives suddenly much less interesting. Raspberry Pi 4 specifications: SoC – Broadcom BCM2711 quad-core Cortex-A72 (ARMv8) @ 1.5GHz with VideoCore VI GPU supporting OpenGL ES 3.0 graphics System Memory – 1GB, 2GB or 4GB LPDDR4 Storage – microSD card slot Video Output & Display I/F 2x micro HDMI ports up to 4Kp60 (Currently 1080p60 max. in dual-display configuration, although 2x 4Kp30 is […]

LEGO Minifigure shaped Mini SAM M4 Board Supports CircuitPython and Arduino

If you are a fan of the Lego movie. Perhaps you have always wanted to use Lego bricks to make something innovative and techy. Then the Mini SAM M4 board is here for you, as it is a LEGO minifigure-sized development board. Additionally, the design and layout of the board is based around the classic 1980’s ‘spaceman’, and is made by Ben Shockley. Although the board is very small, it has a lot of wonderful features. It comes with an analog reference decoupling/filtering capacitors. Also, it has an analog to digital ferrite bead, as well as a debounce circuitry for the reset and user buttons. Furthermore, the board’s software and firmware can be developed using CircuitPython or Arduino. The development board is either based on the Microchip SAMD51G 48-Pin 32-Bit ARM – Cortex M4F MCU (Mini SAM M4), or features the Microchip SAMD21G 48-Pin 32-Bit ARM Cortex -M0+ MCU running […]

Obsidian ESP32 Board Follows Raspberry Pi Model A Form Factor (Crowdfunding)

When Thomas McKahan‏ had been playing with ESP32 for a while, he found the need to use Raspberry Pi HAT boards and enclosure with his new hardware, so he went ahead and designed his own ESP32 board compatible with Raspberry Pi accessories, and following the smaller Raspberry Pi Model A / 3 Model A+ form factor. Obsidian ESP32 specifications: Wireless module – Espressif Systems ESP32-WROVER-B 802.11 b/g/n WiFi + Bluetooth 4.2 / BLE module with 16 MB flash, 8 MB PSRAM USB – 1x micro USB port for power and programming Audio – 3.5mm TRS audio jack connected to ESP32 DACs Expansion 40-pin GPIO header compatible with popular HAT expansion boards with 3.3 V signalling, I²S for audio DAC, I²C and SPI, Serial UART available on header or via microUSB, I²C GPIO expander with interrupts & address selection 8-pim unpopulated header from remaining I/Os accessible through GPIO expander 5-pin unpopulated […]

$9.9 ROCK Pi S is a Tiny SBC Powered by Rockchip RK3308 Processor

Radxa launched their low cost ($40) Rock Pi 4 SBC powered by Rockchip RK3399 processor a little over 18 months ago. If you are subscribed to their mailing list, the company has now sent an email entitled “ROCK Pi Summer Updates 2019” (no link available) that reports about v1.4 of the board with 4MB SPI flash onboard, an external WiFi antenna connector, and various other small changes, as well as the announcement of RockPi PoE HAT to power the board from an Ethernet cable, and an USB 3.0 eMMC card reader. But what particularly caught my attention in the email was a new tiny single board computer powered by Rockchip RK3308 Cortex-A35 processor: Rock Pi S selling for as low as $9.9 with 256MB RAM, and targetting headless IoT & smart voice applications. Rock Pi S board specifications: SoC – Rockchip RK3308 quad-core Arm Cortex-A35 processor with built-in VAD (Voice […]

Dakota DR40X9 Wave-2 AC Router Board is Based on Qualcomm QCA4019/QCA4029 WiSoC

Dakota DR40X9 QCA4019/QCA-4029 Wave-2 AC Router Board

Qualcomm is mostly known for its Snapdragon processors for mobile devices and wearables, but the company is also making WiFi chipsets via their (previously) “Atheros” family. Some of their latest WiFi SoCs are IPQ4019 and IPQ4029 (aka QCA4019/QCA4029) Wave-2 802.11ac “Dakota” SoCs for routers, gateways, and access points. We recently covered the official Qualcomm mesh networking devkit powered by IPQ4019 processor, but there are now third parties also offering solutions based on QCA40x9 processor such as Dakota DR40X9 Wave-2 AC router board. Dakota DR40X9 board specifications: SoC (one of the other) Dakota DR4019 -Qualcomm IPQ4019 quad-core Arm Cortex A7 processor @ 717 MHz with 802.11ac Wave 2 WiFi Dakota DR4029 – Qualcomm IPQ4029 quad-core Arm Cortex A7 processor @ 717 MHz with 802.11ac Wave 2 WiFi System Memory- 256MB~512MB DDR Storage – 2MB~32MB NOR Flash, 128MB NAND Flash, microSD card slot Connectivity Wired Dual 10/100/1000Mbps Gigabit Ethernet (RJ45) 1x optional […]

Perf-V is another FPGA based RISC-V Development Board

There are already some RISC-V development boards with silicon featuring RISC-V instruction set such as SiFive’s HiFive1 or Kendryte KD233 board. But beauty of RISC-V is that you can customize the instructions set, and if that’s your goal, an FPGA board provides the flexibility you need. While in theory you could use pretty much any FPGA board with enough logic elements, it may help to get started with boards that are designed for this purpose since the company already ported a RISC-V core to their platform and you can start from there. We’ve already covered a few of those including LicheeTang and Fomu boards, as well as ARIES M100PF PolarFire FPGA system-on-module. Today, I’ve come across another of those RISC-V FPGA board. Meet Perf-V board with the following specifications: FPGA – Xilinx Artix-7 XC7A35T-1FTG256C with 33280 Logic Cells, 90 DSP, 41600 CLBs, 1800 Kbit Block RAM, and 5 CMTs; Optional […]

DM&P Vortex86EX2 Dual Core Processor Targets Dual OS Systems, Support ISA & PCI Interfaces

Most people will probably think about Intel and AMD when asked about x86 processors, at least those who understand the question… But there are also other companies such as Zhaoxin (based on VIA Technologies designs) and DM&P. Last time I wrote about the latter was in 2015 with the introduction of DM&P Vortex86DX3 dual-core x86 SoC for embedded systems and the corresponding evaluation board. The company is still making new x86 processors, and I’ve just been information the company unveiled Vortex86EX2 dual-core processor last year with master and slave cores suitable for running two operating systems at the same time without the need for virtualization, nor hypervisor. The new processor still supports ISA & PCI interfaces for legacy expansion cards and targets real-time industrial or automation applications. DM&P Vortex86EX2 specifications: Processor Cores Master @ 600MHz max with Build-in FPU L1/L2 Cache for user interface Slave @ 400MHz max with Build-in […]
