Olimex NEO6502 is a W65C02 and Raspberry Pi RP2040-powered retro computer with HDMI, USB, and more

Olimex has recently launched NEO6502 an open-source hardware retro computer designed for educational and entertainment purposes, but that doesn’t mean it can’t be used for retro gaming. The board is very unique as it’s built around a 65C02 MPU and Raspberry Pi Pico RP2040 MCU in a dual-processor configuration. The MOS6502 handles the Apple II, Oric, and Commodore 64 emulators whereas the RP2040 handles everything else including HDMI (DVI) video output using the PicoDVI project. Previously we have written about similar retro computer kits such as the CERBERUS 2100, TinyLlama x86, DevTerm with ClockworkPi v3.14, Olimex AgonLight2, and many others feel free to check those out if you are interested in retro tech with a modern twist.

8devices Carambola 3 WiFi IoT module supports upstream OpenWrt, industrial temperature range

8devices Carambola 3 is a compact System On Module (SoM) built around the Qualcomm QCA4531 WiFi 4 chipset. The module comes in two variants – the Carambola3 for commercial applications (0 to +65°C) and the Carambola3-I for industrial environments (-40 to +85°C). Additionally, 8devices offers a development kit with integrated features like a 2.4 GHz chip antenna, dual LAN ports, USB, GPIO, and much more. Notably, the development kit also supports OpenWrt Upstream, making it ideal for IoT, industrial automation, and smart home projects. The Carambola3 is a pin-to-pin compatible module with the Carambola2, but with a faster processor, more memory, and lower power consumption while the original Carambola was discontinued due to its older technology. 8devices has been developing and selling Wi-Fi modules such as the Rambutan Atheros module, Komikan 802.11ac Wave 2 Module, and recently announced Noni M.2 WiFi 7 module feel free to check those out if […]

LimeNET Micro 2.0 Developer Edition board leverages Raspberry Pi CM4 and LimeSDR XTRX SDR module (Crowdfunding)

The LimeNET Micro 2.0 Developer Edition board is a modular software-defined radio (SDR) platform from Lime Microsystems that is based on the Raspberry Pi Compute Module 4 and the company’s own SDR board, the LimeSDR XTRX. It builds upon previous versions from Lime Microsystems, such as the LimeSDR Mini and LimeSDR Mini 2.0. It features a MIMO (multiple-input, multiple-output) radio and runs the more powerful Compute Module 4, an upgrade from the Raspberry Pi CM3 in earlier versions. The LimeSDR XTRX is an open-source, high-performance SDR in a compact, Mini PCIe form factor. It provides a platform for building logic-intensive digital and RF designs and can be used for MIMO antenna configurations from 2Tx2R to 32Tx32R. The platform is built around a planar system board, the LimePSB RPCM, which integrates the CM4, the XTRX, and other components and interfaces to make a complete baseband + RF solution for diverse wireless […]

GateMate Integrated Logic Analyzer (ILA) deep dive

CNXSoft: This is a guest article by Dave Fohrn, Embedded Software Engineer at Cologne Chip AG, that goes into detail about the company’s open-source integrated logic analyzer (ILA) for GateMate FPGA chips. A field-programmable gate array (FPGA) is a highly flexible integrated circuit in which complex logic circuits can be configured. They are often used as custom computing units in digital circuits because of their ability to process data quickly and in parallel using individually configured circuits. The digital circuits designed specifically for FPGAs are usually developed in a hardware description language such as Verilog or VHDL and are known as gateware. The term “gate” refers to the configurable digital logic units in the FPGA on which the individual gate circuits are implemented. An effective design can accelerate the computing process by strategically utilizing the various resources available in the FPGA, processing data in parallel, and intelligent implementing pipelining. A […]
