Land Boards designs and makes electronics development boards and modules for makers working with embedded computers, microcontrollers, FPGAs, retro computers and ham radio. Its catalog is especially distinctive for spanning modern platforms such as Raspberry Pi and Arduino alongside dedicated retro-computing hardware and Eurorack synthesizer modules. The company also publishes extensive project documentation through its Land Boards Wiki.
Libre ComputerLibre Computer makes single-board computers and compute modules for makers, embedded products, and OEM designs, pairing Pi-compatible hardware with mainline Linux and U-Boot rather than a short-lived vendor kernel. Its Cottonwood platforms, including the Alta and Solitude boards, are built for applications such as edge AI and vision while retaining open software and a path from prototype to production. The company declares a 20-year software support window for most of its platforms and offers design-in support for longer-lived products.
TinyCircuitsAkron-based TinyCircuits designs and manufactures miniature, open-source electronics in the United States, from modular maker boards to programmable handhelds and tiny televisions. Its first product, the TinyDuino platform, launched through Kickstarter in 2012 and raised more than 1,000% of its goal. Today, the company’s solder-free platforms and miniature devices support maker projects, STEAM learning, and a global user community spanning more than 60 countries.AKRON, OH
ComBlockSince introducing its first ComBlocks in 2001, ComBlock has made modular electronics boards, FPGA/VHDL/IP cores, and ready-to-use transceivers for rapidly prototyping complex communication equipment. Its portable VHDL source cores and compact commercial off-the-shelf modules cover communication links from LANs over radio-frequency, satellite, wireless, and cable connections. Customers in more than 55 countries have used tens of thousands of its modules and IP cores.GAITHERSBURG, MD.JPG){kind=logo}
Midnight Design Solutions, LLCMidnight Design Solutions, LLC develops hands-on electronics kits and instruments for amateur-radio experimenters, with a particular focus on compact QRP transceivers, keyers, VFOs and bench tools. Its designs range from the Raspberry Pi Pico-based PicoMite Memory Keyer to the Old Friend, a 6-watt direct-conversion CW transceiver designed by Dave Benson, K1SWL. The company also preserves and advances coherent-CW research, including a low-power transceiver project aimed at copying signals near the noise floor.FOREST HILL, MD
