Hardkernel Celebrates 15 Years by Shrinking the ODROID-M1: Meet the Extra Environment friendly ODROID-M1S

Embedded computing specialist Hardkernel is celebrating its fifteenth anniversary with a brand new single-board pc launch, taking its current ODROID-M1 design and chopping each the scale and the value to make the ODROID-M1S.

“ODROID-M1S is an reasonably priced Arm Cortex-A55 quad-core single board pc with increased power effectivity, slimmer kind issue, and lots of enter/output ports,” Hardkernel writes of its newest design, delivered to our consideration by CNX Software program. “Because of the built-in quick 64GB eMMC storage, 4GB or 8GB LPDDR4 RAM, bundled energy adapter, and bundled case, you may construct your personal embedded system at low price immediately.”

The ODROID-M1S is an replace to, however not a replica of, the year-old ODROID-M1 — considering, Hardkernel says, buyer suggestions which included a want for a smaller, extra energy-efficient design — which, ideally, would additionally price much less. Because of this, the reminiscence velocity has been knocked down just a little, the SATA 3.0 port is gone, there isn’t any MIPI Digicam Serial Interface (CSI) connector, and fewer USB ports.

The system-on-chip, too, has modified: the Rockchip RK3568 with its quad-core Arm Cortex-A55 processor, Arm Mali-G52 MP2 graphics processor, and 0.8 TOPS neural community coprocessor has been changed by the Rockchip RK3566 — dropping the processor efficiency from 2GHz to 1.8GHz, however in any other case retaining the specs of its predecessor. The ODROID-M1’s 16MB of on-board SPI flash, apparently, has been swapped out for a 64GB eMMC benchmarking, Hardkernel claims, at 180MB/s throughput.

The smaller board packs fewer ports, providing just one USB 3.0 and one USB 2.0 port plus a micro-USB 2.0 On-The-Go (OTG) port, plus a USB Kind-C port for energy. There are two general-purpose enter/output (GPIO) headers, a 40-pin Raspberry Pi-style header and a 14-pin header, a UART header for a devoted serial console, 3.5mm analog audio output, gigabit Ethernet, microSD and M.2 M-key NVMe storage choices — the latter dropping from a theoretical most throughput of 1.6GB/s on the ODROID-M1 to 400MB/s on the M1S — and an HDMI 2.0 port with 4k60 help and a four-lane MIPI Show Serial Interface (CSI) connector.

In different phrases, the board delivers an inexpensive number of ports and connections regardless of its smaller dimension — and the transfer to a unique system-on-chip means it additionally delivers on the effectivity entrance. Based on Hardkernel’s inside testing, the ODROID-M1S attracts 1.1W at idle and three.52W underneath heavy CPU load — down from 1.3W idle and 4.5W loaded for the unique ODROID-M1.

Hardkernel is taking orders for the brand new ODROID-M1S on its web site, beginning at $49 for the 4GB mannequin with unpopulated GPIO headers; the corporate has additionally confirmed a spread of equipment, together with a plastic case, eight- and five-inch touchscreen shows, an uninterruptible energy provide (UPS) equipment, and a “Multi IO Coaching Board” which connects to each GPIO headers and provides an OLED show, CAN FD, RS232, and SPI buses, five-key keypad, and extra.
