As far as I know, the EP4CE22 core board is out of stock. SX-2, as a clone of SM-X, deleted the HDMI interface, and the later SM-X HB also did not have an HDMI interface. Even the latest SX-E uses a 55k LE FPGA and does not have HDMI. They need an external VGA to HDMI module to achieve HDMI output, just like the old uMSX.

Existing clones suffered from three critical limitations: excessive thickness, inconsistent norns compatibility, and hardware quirks from early open-source designs. Most DIY monome controllers work with Max\/MSP but are “officially unsupported” for norns and require hacking the C codebase to function.\u003c\/p\u003e\u003cp\u003eWe undertook a complete redesign — rewriting the firmware from scratch and redesigning the PCB layout over six months. Challenges addressed include the unique Arc–norns handshake protocol, encoder acceleration data handling, stable high-refresh-rate performance, and non-functional USB expansion ports found in the original open-source files. The result matches the original’s tactile precision while surpassing it in portability and ecosystem integration.\u003c\/p\u003e\u003ch3\u003eWhat makes it special?\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnprecedented thinness\u003c\/strong\u003e — 12.5mm total thickness, the slimmest Arc clone available; pairs seamlessly with our Grid clone for a unified monome setup\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFull norns compatibility out of the box\u003c\/strong\u003e — a significant breakthrough; most DIY clones struggle with norns integration, which assumes arc connectivity for parameter control and sequencing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuture-proof iii support\u003c\/strong\u003e — hardware is ready for the 2025 monome iii system, enabling Lua scripting and USB-MIDI enumeration directly on the device — something even original pre-2025 arcs cannot do\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePremium build quality\u003c\/strong\u003e — metallic-finish Kexcelled filament; optional aluminum version; RGB LED rings support multi-color adjustment including yellow, white, and green to match norns screen aesthetics\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHand-selected LEDs\u003c\/strong\u003e — each LED individually selected for consistent brightness and color accuracy, with a sophisticated diffusion stack: light shields, reflection layers, and frosted acrylic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCustom ultra-thin encoders\u003c\/strong\u003e — designed in partnership with manufacturers; each unit hand-selected for precision\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eArc4: 256 RGB LEDs\u003c\/strong\u003e — equivalent to a full monome Grid 256; meticulous assembly with multiple 3D-printed diffusion layers and manual QC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLaser-etched inner back panel\u003c\/strong\u003e — eliminates guesswork when locating I\/O ports\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEcosystem compatibility\u003c\/strong\u003e — works with serialosc (Windows\/Mac), norns, VCV Rack Ansible module, and Max\/MSP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLong-term firmware support\u003c\/strong\u003e — regular updates based on community feedback; unique serial number per unit\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eExternal Links\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/llllllll.co\/t\/monome-arc\/71401\"\u003eLines Community Thread\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/monome.org\/docs\/arc\/\"\u003emonome Arc Documentation\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Denjhang's Retro Hardware","offers":[{"title":"Default Title","offer_id":46123574657221,"sku":null,"price":699.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0777\/8507\/1813\/files\/2025-12-25T04_10_33.516Z-O1CN015F9EhX1I7W7NPi1iI__4611686018427386670-0-fleamarket.jpg_Q90.jpg__1.jpg?v=1777006178"}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0777\/8507\/1813\/collections\/2024-01-27T05_29_30.131Z-_H_2KHBB_YSBHX__2O_I9R_tmb.jpg?v=1776836784","url":"https:\/\/denjhang.com\/collections\/frontpage.oembed?page=4","provider":"Denjhang's Retro Hardware","version":"1.0","type":"link"}
