CrowPi L Review – Part 2: Learn programming and electronics with a Raspberry Pi 4 laptop

CrowPi L review learn programming electronics

In the first part of our review of CrowPi L Raspberry Pi 4 laptop for education, we checked the hardware and accessories such as the CrowTail starter kit with various sensors and other electronics modules, and showed how to install or remove the Raspberry Pi 4 SBC from the laptop shell. I’ve now had more time to play with the educational software, so I’ll report my experience with the laptop when learning game design and hardware control with Letscode visual programming IDE, as well as the Python lessons for more advanced students. Reinstalling CrowPi OS image It’s the rainy season here in Thailand meaning it’s both hot and humid, and even though I’m not entirely sure it’s related, I recently had to reinstall Raspberry Pi OS on one of my Raspberry Pi with a corrupted SD card. It happened again with the CrowPi L after I left it in its […]

Inexpensive, Snapdragon 410-based “4G LTE WiFi Modem” made to run Debian 11

4G LTE WiFi Modem Debian 11 Linux 5.15

Some ultra-compact 4G LTE wireless routers housed in what looks like a largish USB dongle are based on Qualcomm Snapdragon 401 (MSM8916) quad-core Cortex-A53 processor and have been hacked to run Debian 11 with Linux 5.15 instead of the pre-loaded Android OS. Soon after Extrowerk had purchased a ~$20 “4G LTE WiFi modem” USB dongle, he noticed it would show as “Android” when connected to his PC. It also turned out that Chinese hacker HandsomeYingYan had already done some work on the device modding the lk2nd bootloader and the Linux kernel for the OpenStick project for “mainline Linux on msm8916-based 4G USB modem”, and documented his work (in Chinese) to run Debian 11 on the “4G USB WiFi Modem” pictured below. Let’s go through some of the specifications of the said wireless router: SoC – Qualcomm Snapdragon 410 (MSM8916) quad-core Arm Corte-A53 processor with System Memory – 512 MB RAM […]

mini PCIe module features Rockchip RK1808K SoC with 3.0 TOPS NPU

Toybrick RK1808 mPCIe AI accelerator card

Rockchip RK1808 SoC with a built-in 3.0 TOPS AI accelerator has been around since 2019, and we’ve seen it in USB compute sticks, SBCs, and even in Pine64 SoEdge-RK1808 SO-DIMM module, but somehow never in the more widely used M.2 or mPCIe form factors. Toybrick TB-RK1808M0 changes that and offers Rockchip RK1808K SoC coupled with 1GB RAM and an 8GB eMMC flash in a mini PCIe module that exposes USB 3.0, USB 2.0, UART, and GPIO signals. Toybrick TB-RK1808M0 specifications: SoC – Rockchip RK1808K CPU – Dual-core Cortex-A35 processor @ up to 1.4 GHz AI Accelerator – 3.0 TOPS NPU for INT8 inference (300 GOPS for INT16, 100 GFLOPS for FP16) VPU – 1080p60 H.264 decode, 1080p30 H.264  encode System Memory – 1GB DDR Storage – 8GB eMMC flash Host interface – Mini PCIe edge connector with USB 3.0, USB 2.0, UART, and GPIO Misc – Heatsink for cooling Supply […]

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

Rockchip RK3566 SBC vs Raspberry Pi 3

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, […]

Rock 5B RK3588 SBC preview – What works, what doesn’t in Debian 11

Rock 5B review Debian 11

I’ve recently received an early sample of Radxa ROCK5 Model B (aka ROCK 5B) SBC part of the “Developer Edition” batch with 16GB RAM, and already showed the hardware and it booting successfully in Debian 11.

I’ve now spent more time with the board, and as part of the “debug party” tested performance and features in Debian 11. As one would expect, some things work fine, providing excellent performance, but others still need improvements.

Geniatech XPI-3566 is a business-card sized Rockchip R3566 SBC

Geniatech XPI-RK3566

Geniatech has added a new member to its XPI SBC family with the business card-sized XPI-3566 board powered by a Rockchip RK3566 quad-core Cortex-A55 processor, and mostly following the Raspberry Pi 3 form factor like its predecessors. The single board computer comes with 1GB to 8GB RAM, up to 64GB eMMC flash, HDMI 2.0 video output, Gigabit Ethernet, dual-band WiFi, a few USB ports, and a 40-pin GPIO header. It is said to target retail, “interactive communication”, and education applications. Geniatech XPI-3566 specifications: SoC – Rockchip RK3566 quad-core Cortex-A55 processor @ up to 1.8 GHz with Arm Mali-G52 2EE GPU, 0.8 TOPS AI accelerator System Memory – 2GB DDR (1GB, 4GB, or 8GB optional) Storage 16GB eMMC flash (8GB, 32GB, 64GB optional) MicroSD card socket Video Output HDMI 2.0 up to 4Kp60 MIPI DSI connector (not listed in the specs, but it can clearly be seen on the board) Camera […]

ROCK 5B developer edition preview – Part 1: Unboxing and first boot to Debian 11

ROCK 5B Rockchip RK3588 SBC

Radxa ROCK5 Model B (aka ROCK 5B) is one of the most anticipated Rockchip RK3588 single board computers due to its features set and relatively affordable price. It was first showcased in January, but it’s taking a while as the Cortex-A76/A55 SoC is a complex beast. The good news is that the public launch is getting closer as Radxa sent “developer edition” samples to developers and enthusiasts for a “debug party”. I was one of the recipients so, in this post, I’ll have a closer look at the latest revision of the board, and give it a quick try first before going into more details in the second of this preview. ROCK5 Model B unboxing I received the 16GB RAM version which should be the same for all board part of the “developer edition batch. Developers are invited to submit reports to Radxa forums, and since those are public, anybody […]
