What JK microsystems, Inc does

JK microsystems, Inc. is a privately held California corporation founded in 1996, headquartered in Grass Valley, CA, that designs and sells embedded single board computers (SBCs), microcontrollers, and peripheral expansion boards for industrial control, information appliance, data acquisition, and networked embedded applications. The company targets embedded systems developers, industrial control engineers, and OEMs building low-volume, cost-sensitive embedded products.

The core product portfolio is built around two technology pillars: (1) DOS-based SBCs using Intel 386Ex processors with a proprietary in-house BIOS written in Masm and a custom DOS implementation (XDOS) compatible with MS/PC DOS 3.3, and (2) ARM 9-based Linux microcontrollers. Product lines include Flashlite 186, Flashlite 386Ex, LogicFlex (embedded Ethernet SBC), LogicFlex-EPX (1RU rackmount industrial controller), picoFlash, OmniFlash (ARM9 Linux), and DiskOnChip flash storage accessories. Pricing spans $33-$599 per unit, with development kits and peripheral expansion boards (A/D, D/A, relays, isolated I/O, serial ports) sold separately.

The company operates a direct-to-consumer hardware sales model through an e-commerce storefront on BigCommerce (stores.jkmicro.com), complemented by an international distributor network covering Australia, France, Germany, and Spain. Revenue is generated from one-off hardware sales with quantity discounts negotiated via sales contact. The business appears to be founder/owner-operated with no disclosed institutional investment, no management team bios available, and no headcount disclosed. The website copyright dates to 2016, and the technology stack relies on legacy architectures including Linux Kernel 2.4, indicating a mature, maintenance-mode business rather than a growth-stage venture.

Core offering

JK microsystems designs, manufactures, and sells low-cost embedded single board computers (SBCs) and microcontrollers — including DOS-based SBCs (Flashlite 186, Flashlite 386Ex), embedded Ethernet controllers (LogicFlex, LogicFlex-EPX), and Linux ARM 9 controllers (OmniFlash) — along with complementary accessories such as DiskOnChip flash storage, PowerNut power controllers, and LCD displays. The SBCs target embedded systems developers and industrial control engineers, providing built-in Ethernet, TCP/IP, serial ports, and configurable digital I/O for industrial control, information appliances, data acquisition, and networking applications.

Product overview

JK microsystems, Inc offers a comprehensive line of embedded single board computers and microcontrollers. The core product portfolio includes DOS-based SBCs (Flashlite 186, Flashlite 386Ex), embedded Ethernet controllers (LogicFlex, LogicFlex-EPX rackmount system), and Linux microcontrollers (OmniFlash). These products share a common architecture based on Intel 386EX processors or ARM processors, pre-loaded with DOS or Linux operating systems, featuring serial ports, digital I/O, and optional Ethernet connectivity. The company also provides complementary accessories including DiskOnChip flash storage, peripheral expansion boards (pico I/O, Multi-I/O, Serial/Parallel), LCD displays, power controllers (PowerNut), and development kits. The product ecosystem is unified by compatible form factors, common programming interfaces (supporting C, QuickBASIC), and shared peripheral boards that expand I/O capabilities across the product line.
