Hardkernel has released the ODROID-M1S, a smaller and more cost-effective single-board computer (SBC) compared to the previously launched ODROID-M1. Designed to commemorate Hardkernel’s 15th anniversary, the ODROID-M1S is priced at $49 and up and features the Rockchip RK3566 system-on-a-chip (SoC).

The ODROID-M1S SBC comes with the Rockchip RK3566 SoC, which is similar to the RK3568 but with fewer peripheral interfaces. The board offers 4GB or 8GB LPDDR4 memory, a 64GB eMMC flash soldered onto the board, HDMI 2.0 and MIPI DSI video interfaces, gigabit Ethernet, a few USB ports, and two GPIO headers. However, compared to the ODROID-M1, the ODROID-M1S does have some feature losses, such as a lower-speed memory, PCIe 2.1 support, the removal of the SPI flash and SATA port, and the MIPI CSI camera connector. The power supply has also been changed from a 12V DC jack to a 5V USB-C port.

Here are the specifications of the ODROID-M1S with the differences from the ODROID-M1 highlighted:

• SoC – Rockchip RK3566 quad-core Cortex-A55 processor @ up to 1.8 GHz with Arm Mali-G52 MP2 GPU @ 800 MHz and 0.8 TOPS AI accelerator
• System Memory – 4GB or 8GB LPDDR4 RAM at 2112 MT/s or up to 1,055 MHz
• Storage
  • 64GB eMMC flash (soldered on PCB) benchmarked at up to 180MB/s with fio
  • MicroSD card slot (UHS-I SDR104, boot priority higher than eMMC flash)
  • M.2 NVMe M-Key 2280 socket (2-lane PCIe 2.1) benchmarked at up to 400MB/s with fio
• Video Output
  • 1x HDMI 2.0 port up to 4Kp60 with HDR and EDID
  • 4-lane MIPI DSI connector (30-pin, while ODROID M1 has a 31-pin connector)
• Audio – 3.5mm headphone jack, mono speaker output (1.3W at 8Ω load)
• Networking – Gigabit Ethernet RJ45 port via Realtek RTL8211F Ethernet transceiver
• USB
  • 1x USB 3.0 port
  • 1x USB 2.0 port
  • 1x Micro USB 2.0 OTG port
• Expansion – 40-pin GPIO header + 14-pin GPIO header (both headers optional)

EDATEC has released two fanless cases for the Raspberry Pi 5 single-board computer (SBC), filling the gap for official fanless cases for this latest SBC. The two cases, ED-Pi5Case-B and ED-Pi5Case-O, offer different designs and cooling solutions.

Both cases are made of aluminum and are available in either silver or black. They provide easy access to all ports and interfaces of the Raspberry Pi 5, including the GPIO header, MIPI connectors, PCIe FPC connector, and PoE header. However, the closed enclosure blocks the battery and UART connectors, while both cases block the fan connector.

EDATEC claims that the ED-Pi5Case-B can reduce the temperature by 20 to 25°C, while the lighter ED-Pi5Case-O can reduce it by up to 15°C. Both cases come with three thermal pads to cover the Broadcom BCM2712 CPU, the wireless module, and the PMIC. They also add thermal conductive silicon on the bottom of the board.

The ED-Pi5Case-B features a low-profile, closed design with a small black plastic window on the top right for wireless connectivity. EDATEC states that this case benefits from strong WiFi and Bluetooth connectivity, enhanced by the semi-transparent wireless window. On the other hand, the ED-Pi5Case-O is an open case with two heatsinks placed on the top and bottom of the Raspberry Pi 5.

The HUNSN BM34 mini PC offers a compact design with extensive connectivity options. It features three video outputs, two Ethernet ports, mic and speaker jacks, a DC power input, and eight USB ports. However, only two of the USB ports support USB 3.0 speeds. The PC also supports multiple storage options, including an M.2 2280 PCIe NVMe SSD, an mSATA SSD, and a 2.5-inch hard drive or SSD. It can accommodate up to 16GB of DDR4-3200 memory and is powered by an Intel Processor N100 chip.

The fanless design and low-power processor make it suitable for silent operation. The PC is available on Amazon starting at $200 for the barebones model. It can be used for various purposes, including as a low-power router or home media server.
