The just-announced Raspberry Pi Zero 2 W is not the first quad-core Arm SBC following Raspberry Pi Zero form factor, and back in 2017, the Banana Pi BPI-M2 Zero was introduced for $15, and the Radxa Zero was unveiled last June with an Amlogic S905Y2 SoC with price starting at $15 as well. With its Allwinner H2+ quad-core Cortex-A7 processor clocked at 1 GHz and a price bumped up to $23, the Banana Pi M2 Zero has mostly become irrelevant, but the Radxa Zero may still be considered by some people with a 1.8 GHz processor, and options for up to 4GB RAM, so let’s see how features compare against Raspberry Pi Zero 2 W, followed by some benchmark numbers. Raspberry Pi Zero 2 W vs Raxda Zero – Features If we just look at the comparison table, the Radxa Zero is equivalent or superior in almost every way, except […]
Giveaway Week – NanoPi R2S gateway
Here’s the 8th edition of CNX Software giveaway week! I’ll have seven items to give away to readers in the 2021 event with some help from two companies as I was short on available samples this year. We’ll start with NanoPi R2S gateway based on Rockchip RK3328 SoC, and equipped with 1 GB DDR4 RAM as well as two Gigabit Ethernet ports. I reviewed NanoPi R2S gateway at the end of last year with Armbian built Ubuntu 20.04 Focal, and it performed well under load thanks to the metal enclosure and optimized OS. The main downside is having a USB 2.0 port, especially if you intend to use it as external storage, but that’s the cost of having two Gigabit Ethernet ports on Rockchip RK3328 SoC, with one of those using the USB 3.0 interface. The giveaway includes the board and metal enclosure. It is already fully assembled. So you’ll […]
Build an open source-hardware Allwinner D1s RISC-V Linux SBC for under $10
We covered Allwinner D1s RISC-V processor with 64MB built-in RAM a few days ago, and we’ve just found out about Xassette-Asterisk, an open-source hardware board based on the processor that runs Linux (OpenWrt) and is said to cost less than $10 to make. This is significantly cheaper than the Allwinner D1 based Nezha RISC-V Linux SBC currently sold for a little over $100, a rather poor value. The cheaper board will not quite have the same applications with just 64 MB RAM and no HDMI, but it could be great for projects requiring a camera and/or a display, audio interfaces, plus some I/Os. Xassette-Asterisk specifications: SoC – Allwinner D1s single-core 64-bit RISC-V processor @ 1.008 GHz with 64MB DDR2 Storage – MicroSD card slot, 32 MBit SPI flash (W25Q32 – U2 on the board) Display I/F – 40-pin LCD connector, 6-pin touch panel interface, backlight power Camera I/F – 24-pin […]

SolidRun i.MX 8XLite SoM embeds DSRC modem, GPS for V2X automotive applications
The GPU-less NXP i.MX 8XLite Cortex-A35/M4 SoC was just announced earlier this month for V2X and IIoT applications, and now SolidRun unveiled the first module based on the new processor with the “i.MX 8XLite System-on-Module”. Also equipped with a RoadLINK SAF5400 safety modem, SolidRun’s Mini SoM targets vehicle telematics, vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communications, road infrastructure connectivity, and industrial equipment. SolidRun i.MX 8XLite specifications: SoC – NXP i.MX 8XLite single or dual-cire Cortex-A35 processor @ 1.2 GHz, with Cortex-M4F real-time core System Memory – 1GB LPDDR4 with inline ECC Storage – 8GB eMMC flash Ethernet – NXP TJA1100 100BASE-T1 Automotive Ethernet transceiver Wireless NXP RoadLink SAF5400 DSRC/802.11p (V2X) single modem dual antenna (u.FL connectors) GNSS module for GPS 2x Hirose DF40 board-to-board connectors with: Storage – SD/MMC card, PCIe SSD Ethernet – 100BASE-T1 Automotive Ethernet USB – 2x USB 2.0 PCIe – 1x PCIe Low-speed interfaces – 2x I2C, […]
Raspberry Pi Zero 2 W and Zero W features comparison
The Raspberry Pi Zero 2 W quad-core board has just launched, and in this post, we’ll look at how the new board compares to the original Raspberry Pi Zero W SBC. From the photos above they are nearly identical, but looking at the detailed specifications, we’ll find some interesting differences. So the main reasons to get a Raspberry Pi Zero 2 W over a Raspberry Pi Zero W is the extra performance enabled by the quad-core Cortex-A53 processor and possibly better wireless performance. The downsides are at the new board costs $5 more, and power consumption might be higher, but this would have to be tested under various scenarios. Another reason you may end up getting the Zero 2 W board that is not shown in the specifications is the recent shortage of chips, so the new board may be more likely to be in stock at your local distributor.

$15 Raspberry Pi Zero 2 W launched with quad-core CPU, 512MB RAM
Raspberry Pi Zero 2 W is the first quad-core SBC from the Raspberry Pi Foundation with the Raspberry Pi Zero form factor. Based on the RP3A0 system-in-package (SiP) comprised of a Broadcom BCM2710A1 quad-core Cortex-A53 processor and 512MB LPDDR2, the new Pi Zero W 2 board offers the exact same interfaces as its predecessor. This includes a MicroSD card socket, a mini HDMI port, two micro USB ports, a MIPI CSI-2 camera connector, as well as an unpopulated 40-pin GPIO header. The wireless module appears to have changed but still offers WiFi 4 and Bluetooth 4.x BLE, and it’s using the same VideoCore IV GPU to handle 3D graphics and video encoding and decoding up to 1080p30. Raspberry Pi Zero 2 W specifications: SiP – Raspberry Pi RP3A0 system-in-package with: SoC – Broadcom BCM2710A1 quad-core Arm Cortex-A53 @ 1GHz (overclockable to 1.2 GHz) with VideoCore IV CPU supporting OpenGL ES […]
