I <a href=\"https:\/\/itsfoss.com\/arosom-sige7-review\/\">reviewed the Sige7<\/a> a while back and came away impressed (cheeky headline and all). Earlier this year, we also covered the <a href=\"https:\/\/itsfoss.com\/news\/armsom-sige6-launched-with-allwinner-soc\/\">Sige6<\/a>, the first Sige board to swap Rockchip for Allwinner.<\/p>\n<p>Now the Sige lineup is back on Rockchip with the <a href=\"https:\/\/www.armsom.org\/sige7s\">Sige7s<\/a>. So, what&#8217;s changed?<\/p>\n<figure class=\"kg-card kg-image-card\"><img decoding=\"async\" src=\"https:\/\/itsfoss.com\/content\/images\/2026\/10\/armsom-sige7s-1.webp\" class=\"kg-image\" alt=\"ArmSoM Sige7s\" loading=\"lazy\" width=\"1000\" height=\"521\" \/><\/figure>\n<h2>Key Specifications<\/h2>\n<ul>\n<li>SoC: Rockchip RK3588S, 8nm, 4x Cortex-A76 @ 2.4GHz + 4x Cortex-A55 @ 1.8GHz<\/li>\n<li>AI: 6 TOPS NPU (INT4\/INT8\/INT16)<\/li>\n<li>RAM: up to 32GB LPDDR4\/4X<\/li>\n<li>Storage: removable eMMC module (16GB to 128GB) + microSD<\/li>\n<li>Networking: Wi-Fi 6 + Bluetooth 5.0, Gigabit Ethernet with PoE support (add-on module)<\/li>\n<li>2x USB 3.0 + 2x USB 2.0<\/li>\n<li>1x MIPI CSI (up to 5MP camera)<\/li>\n<li>CAN, SPI, PWM, 3x UART, 2x I2C, 6x ADC<\/li>\n<li>RTC battery connector<\/li>\n<li>Headphone out<\/li>\n<li>Power and Maskrom buttons<\/li>\n<li>0\u00b0C to 80\u00b0C operating temperature<\/li>\n<li>Size: 85 x 56 x 17mm, same footprint as a Raspberry Pi<\/li>\n<\/ul>\n<figure class=\"kg-card kg-image-card\"><img decoding=\"async\" src=\"https:\/\/itsfoss.com\/content\/images\/2026\/10\/Sige7s_interface-1.webp\" class=\"kg-image\" alt=\"Sige7s Interface\" loading=\"lazy\" width=\"624\" height=\"407\" \/><\/figure>\n<p>The Sige7s starts at $153 on ArmSoM&#8217;s store. <\/p>\n<p>The &#8220;s&#8221; in the name comes from the chip. The RK3588S is the trimmed-down version of the RK3588 that powers the Sige7. You get the same CPU, the same Mali-G610 MP4 GPU, and the same 6 TOPS NPU. What you lose is peripheral bandwidth. There is no PCIe 3.0, one HDMI output instead of two, no HDMI input, and only one Gigabit Ethernet controller.<\/p>\n<p>In simpler words, the compute is the focus here, the I\/O is not. If you want a Rockchip SBC fast NVMe drive or dual networking, this isn&#8217;t the board for you. If you want RK3588-class power in a smaller package for less money, it is.<\/p>\n<figure class=\"kg-card kg-image-card\"><img decoding=\"async\" src=\"https:\/\/itsfoss.com\/content\/images\/2026\/10\/Sige7s_interface-2-1.webp\" class=\"kg-image\" alt=\"ArmSoM Sige7s\" loading=\"lazy\" width=\"625\" height=\"366\" \/><\/figure>\n<p>There are a few more indirect cost optimizations here for the users. Sige7s accepts a wide 5V to 23V input, so you aren&#8217;t stuck with a specific USB-C power brick. It also uses a <strong>removable eMMC module<\/strong>, which means your precious storage isn&#8217;t stuck to the board if you want to upgrade or reflash it on another machine.<\/p>\n<p>On the display side, there&#8217;s HDMI 2.1 up to 8K@60fps, a DisplayPort 1.4 over USB-C, and a 2-lane MIPI DSI connector. The hardware video engine decodes 8K@60fps H.265\/VP9 and encodes 8K@30fps, so it can double as a serious media box.<\/p>\n<figure class=\"kg-card kg-image-card\"><img decoding=\"async\" src=\"https:\/\/itsfoss.com\/content\/images\/2026\/10\/armsom-sige7s-2-1.webp\" class=\"kg-image\" alt=\"ArmSoM Sige7s\" loading=\"lazy\" width=\"1000\" height=\"435\" \/><\/figure>\n<p>The <strong>40-pin header is Raspberry Pi compatible<\/strong>, and ArmSoM says it works with <a href=\"https:\/\/itsfoss.com\/raspberry-pi-hat\/\" rel=\"noreferrer\">Pi HATs<\/a>, the Pi 7-inch display, the IMX219-based Pi camera, and Pi 4 cooling solutions. That&#8217;s a good thing if you already have Pi accessories in your stock or if you want to expand the board.<\/p>\n<h2>Prefer a Compute Module? Meet the CM7s<\/h2>\n<figure class=\"kg-card kg-image-card\"><img decoding=\"async\" src=\"https:\/\/itsfoss.com\/content\/images\/2026\/10\/ArmSom-Cm7s-2.webp\" class=\"kg-image\" alt=\"ArmSoM CM7s\" loading=\"lazy\" width=\"600\" height=\"450\" \/><\/figure>\n<p>Alongside the Sige7s, ArmSoM also offers the <a href=\"https:\/\/www.armsom.org\/cm7s\">CM7s<\/a>, a compute module built around the <strong>same RK3588S chip<\/strong>. I checked both spec pages, and the CPU, GPU, NPU, and video engine are identical. It&#8217;s just a different form factor.<\/p>\n<p>In case you did not know, the compute module contains just the processor, memory, storage, and power management. There are no standard physical input\/output ports like USB, HDMI, and Ethernet. Compute modules are more suitable in cases where they need to be embedded.<\/p>\n<p>The CM7s measures 55 x 40mm, pretty much the same size as the Raspberry Pi CM5. Not sure if you can put it into a CM5 carrier board, though.<\/p>\n<p>It&#8217;s available with up to 32GB LPDDR4\/4X RAM and up to 256GB eMMC. Through the 100-pin connectors, it exposes HDMI 2.1, DP 1.4, MIPI CSI\/DSI, USB 3.0, PCIe 2.0\/SATA, and the usual GPIO buses. ArmSoM has also committed to producing it until at least August 2034, which is reassuring if you&#8217;re building a product around it.<\/p>\n<p>To get started, there&#8217;s the CM7s-IO carrier board. It gives you HDMI, USB-C DisplayPort, 4x USB 3.0, Gigabit Ethernet, a 40-pin header, an M.2 M-key slot for NVMe SSDs, microSD, and MIPI camera and display connectors. Unlike the Sige7s, it runs on a 12V DC barrel jack.<\/p>\n<h2>Pricing and Availability<\/h2>\n<p>Both boards are available now from ArmSoM&#8217;s official store, with AliExpress and Taobao listings as well. <\/p>\n<p>The Sige7s starts at $153. Wi-Fi antennas are sold separately, so add those to your cart. <\/p>\n<div class=\"kg-card kg-button-card kg-align-center\"><a href=\"https:\/\/www.armsom.org\/product-page\/sige7s\" class=\"kg-btn kg-btn-accent\">ArmSoM Sige7s<\/a><\/div>\n<p>The CM7s starts at $179.<\/p>\n<div class=\"kg-card kg-button-card kg-align-center\"><a href=\"https:\/\/www.armsom.org\/cm7s\" class=\"kg-btn kg-btn-accent\">ArmSoM CM7s<\/a><\/div>\n<p>If you&#8217;re in the US, note that ArmSoM collects 25% of the product value as prepaid customs duty at checkout (listed as &#8220;sales tax&#8221;), so there&#8217;s no surprise bill on delivery.<\/p>\n<p>If you just want a ready-to-use RK3588S computer, go for the Sige7s. If you&#8217;re designing your own hardware or want an NVMe slot via the carrier board, the CM7s is the one.<\/p>\n<p>ArmSoM hardware might remind you of Banana Pi boards, that&#8217;s because the two companies are known to work closely together, and the boards often share the same base.<\/p>\n<p>One more thing worth I have noticed. ArmSoM&#8217;s documentation has improved considerably since I first tried their boards. That&#8217;s a positive sign because new SBCs often struggle with the documentation and community.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/feed.itsfoss.com\/link\/24361\/17505121.gif\" height=\"1\" width=\"1\" \/><\/p>","protected":false},"excerpt":{"rendered":"<p>If you&#8217;ve followed It&#8217;s FOSS for a while, you probably have seen our previous coverage of ArmSoM devices.
