Rockchip RK3582 is a cost-down version of RK3588S with two Cortex-A76 cores, four Cortex-A55 cores, no GPU

Rockchip RK3582 hexa-core SoC is pin-to-pin compatible with the popular Rockchip RK3588S octa-core Cortex-A76/A55 SoC, but only features two Cortex-A76 cores, a 5 TOPS NPU (instead of 6 TOPS) and does not come with a 3D GPU. I was first made aware of the Rockchip RK3582 in October 2023 when I was sent a photo of a board allegedly for a TV box, but while the RK3582 still features a 4K video decoder, the lack of a 3D GPU could make it problematic with 3D accelerated user interface. We now have more details with Radxa having released the datasheet and a few more interesting details. Rockchip RK3582 specifications: Hexa-core CPU – 2x Cortex-A76 and 4x Cortex-A55 cores in dynamIQ configuration (frequencies are still shown as TBD in the datasheet) GPU No 3D GPU 2D graphics engine up to 8192×8192 source, 4096×4096 destination AI Accelerator – 5 TOPS NPU 3.0 (Neural […]

Duo S RISC-V/Arm SBC features Sophgo SG2000 SoC, Ethernet, WiFi 6, and Bluetooth 5 connectivity

Duo S SBC Sophgo SG2000 Ethernet WiFi 6 Bluetooth

Shenzhen MilkV Technology’s Duo S is a tiny SBC based on the 1 GHz Sophgo SG2000 Arm Cortex-A53 and RISC-V SoC with 512MB DDR3 (SiP), Fast Ethernet, WiFi 6, and Bluetooth 5 connectivity, and a switch to select Arm or RISC-V architecture before powering the board. We already had covered SG2002 Arm/RISC-V boards with 256MB RAM, namely the LicheeRV Nano and Duo 256M, but for people needing more memory, the Duo S provides another option that also features two 2-lane MIPI CSI connectors, a USB 2.0 host port, and two 26-pin headers for expansion. Its form factor reminds me of FriendlyELEC’s NanoPi NEO and family powered by Allwinner processors that were introduced a few years ago. Duo S specifications: SoC – SOPHGO SG2000 Main core – 1 GHz 64-bit RISC-V C906 or Arm Cortex-A53 core (selectable) Minor core – 700 MHz 64-bit RISC-V C906 core Low-power core – 25 to […]

SparkFun’s latest GNSS breakout board features u-Blox NEO-F10N L1/L5 dual-band receiver for urban environments

The SparkFun GNSS L1/L5 Breakout is a standard precision GNSS board with meter-level positional accuracy that features the u-Blox NEO-F10N dual-band module, an SMA antenna connector, and a USB-C port for power and data. As its name implies, the board relies on the L1/L5 bands of the NEO-F10N instead of the more commonly seen L1/L2 bands and delivers better performance in urban environments. That’s because the L5 band falls within the protected ARNS (aeronautical radionavigation service) frequency band leading to less RF interference. SparkFun GNSS L1/L5 Breakout specifications: GNSS u-Blox NEO-F10N module with L1/L5 dual-band GNSS receiver Concurrent Reception of GPS, Galileo, and Beidou Integrated SMA Connector Time to First Fix: 28s (cold), 2s (hot) Max Navigation Rate for Single GNSS Configuration (GPS): 20 Hz Positional Accuracy (GPS) – 1.5m Time Pulse Accuracy – 30ns Operational Limits Max G: ≤ 4G Max Altitude: 80km Max Velocity: 500m/s Supports NMEA, UBX […]

Radxa Penta SATA HAT adds up to five SATA drives to the Raspberry Pi 5 for NAS applications

The Radxa Penta SATA HAT leverages the PCIe interface on Raspberry Pi 5 SBC to add up to five 2.5-inch or 3.5-inch SATA drives through four SATA connectors and an eSATA connector and enables NAS designs with the latest SBC from Raspberry Pi Limited. The Radxa’s Penta SATA HAT was initially launched in 2019 as an accessory for the Rock Pi 4 SBC powered by a Rockchip RK3399 processor and an M.2 PCIe socket since Raspberry Pi competitors have been exposing PCIe interfaces for years. It turns out the exact same Penta SATA HAT design can be reused with the Raspberry Pi 5 by providing a new PCIe FPC cable and updating the configuration scripts. Radxa Penta SATA HAT for Raspberry Pi 5 specifications: 4x SATA interfaces + 1x eSATAp for up 100TB storage via 5x 2.5″ or 3.5″ HDD/SSD Host Connection – Flat cable with 2-lane PCIe 2.1 via […]
