Banana Pi BPI-W3 SBC features Rockchip RK3588 SoM, M.2 NVMe socket, 2.5GbE, HDMI output and input

Banana Pi BPI-W3

Banana Pi BPI-W3 is another Rockchip RK3588 SBC (single board computer) with 8GB RAM, 32GB eMMC flash, an M.2 NVMe socket, 2.5GbE networking, two HDMI 2.1 output ports, one HDMI 2.0 input port, and other features. We first recovered the board last summer, but at the time the RK3588 SBC came with a PCIe x4 slot and dual Gigabit Ethernet, and the company has now redesigned the board without either using instead a Rockchip RK3588 system-on-module as part of the design and implemented 2.5GbE and M.2 NVMe SSD support with the available PCIe interfaces. Banana Pi BPI-W3 specifications: SoM – BPI-RK3588 core board SoC- Rockchip RK3588 octa-core processor with 4x Cortex-A76 cores @ up to 2.4 GHz, 4x Cortex-A55 cores @ 1.8 GHz, an Arm Mali G610MC4 GPU, a 6 TOPS NPU, 8Kp60 H.265/VP9/AVS2 10-bit decoder, 8Kp30 H.265/H.264 encoder System Memory – 8GB LPDDR4 (options for 4GB to 32GB) Storage […]

XCVR LoRa-based IoT development board & reference design features SX1261, SX1262, or LLCC68 chip

XCVR LoRa based IoT development board

Semtech Corporation and “Connected Development” engineering firm have launched the XCVR development board and reference design based on Sentech SX1261, SX1262, or LLCC68 transceivers with the last one targeting Smart Home applications. The XCVR development board is actually an Arduino shield that’s been tested with Nordic nRF52840-DK board, but should work with most boards equipped with Arduino Uno headers. It can be used for the design of LPWAN IoT applications using SX1262x transceivers such as smart meters, industrial controllers, asset tracking, building automation, smart agriculture, etc… while the LLCC68 model is more useful for Smart Home applications and consumer devices. XCVR shield specifications and features: LoRa and FSK Modem Programmable bit rate up to 62.5 kbps LoRa and 300 kbps FSK External antenna Link budget 163 dB maximum for SX1261 170 dB maximum for SX1262 configurations. Tx Power +15 dBm high-efficiency PA for SX1261 +22 dBm or +15 dBm high-efficiency […]

Linux 6.3 release – Notable changes, Arm, RISC-V and MIPS architectures

Linux 6.3 release

Linux Torvalds has just announced the release of Linux 6.3 on the Linux Kernel Mailing List (LKML): It’s been a calm release this time around, and the last week was really no different. So here we are, right on schedule, with the 6.3 release out and ready for your enjoyment. That doesn’t mean that something nasty couldn’t have been lurking all these weeks, of course, but let’s just take things at face value and hope it all means that everything is fine, and it really was a nice controlled release cycle. It happens. This also obviously means the merge window for 6.4 will open tomorrow. I already have two dozen pull requests waiting for me to start doing my pulls, and I appreciate it. I expect I’ll have even more when I wake up tomorrow. But in the meantime, let’s enjoy (and test) the 6.3 release. As always, the shortlog […]
