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

Olimex Neo6502 Dev Board

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.

The Pico Display Base Board offers a simpler way to create Raspberry Pi Pico LCD projects

Pico Display Base Board

The Pico Display Base Board is a printed circuit board from Applying Microcontroller Solutions that provides a platform for building Raspberry Pi Pico-based display projects. It works with a Raspberry Pi Pico board and an LCD screen based on the Solomon Systech SSD1963 display controller. The Pico Display Base Board features a 40-pin header (Display Port) which connects to GPIO on the Pico to provide an 8-bit parallel interface for the display and SPI pins for the touchscreen and integrated SD card. It supports various display sizes from 4.3 inches up to 7 inches. Displays up to five inches can be powered directly by the Pico. A jumper block on the board can be used to pass power to the LCD and wire the display’s optional flash chip to the Pico. A USB-C port on the board can provide an alternative power source for larger displays. It also has male […]

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

LimeNET Micro 2.0 developer edition

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 […]

Apple’s Embedded Swift programming language supports ESP32-C6, Raspberry Pi RP2040, STM32F7, nRF52840 microcontrollers

ESP32-C6 Apple Swift

Apple has released a beta version of Embedded Swift that notably works with Espressif ESP32-C6 wireless RISC-V microcontroller, and the company also built a Matter sample based on ESP-IDF and ESP-Matter SDKs. Embedded Swift is not limited to the ESP32-C6 and supports other microcontrollers from STMicro, Raspberry Pi, Nordic Semi, etc… Apple Swift programming language is mostly designed for mobile app development, but we’ve also seen it being used on Mad Machine’s SwiftIO board powered by a 600 MHz NXP i.MX RT1052 Arm Cortex-M7 crossover processor and the tiny SwiftIO Micro launched a few years later. The company has now decided to create a subset of the Swift programming language better suited to microcontrollers simply called Embedded Swift that’s currently working on STMicro STM32F746, Raspberry Pi Pico, nRF52840, and ESP32-C6. The “Go small with Embedded Swift” presentation at WWDC 2024 shows how to get started with Embedded Swift using Espressif […]

The RPGA Feather dev board pairs RP2040 chip with a Lattice iCE40 FPGA for sensor fusion projects

rpga feather board

Oak Development Technologies’ RPGA Feather board integrates the Raspberry Pi RP2040 microcontroller with the iCE5LP4K FPGA from Lattice Semiconductor into a compact development board in the Adafruit Feather form factor. The iCE5LP4K FPGA is an ultra-low-power chip in the iCE40 Ultra product family designed for mobile applications such as smartphones, tablets, and handhelds, while the Raspberry Pi RP2040 microcontroller makes it much easier to program the FPGA using CircuitPython. We have seen Oak Development Technologies’ earlier forays into FPGA Feather-compatible products such as the IcyBlue board (also based on iCE5LP4K FPGA) and the Lattice FeatherWing. RPGA Feather specifications: MCU – Raspberry Pi RP2040 dual-core Cortex-M0+ microcontroller @ 133 MHz with 264KB SRAM FPGA – Lattice Semiconductor iCE5LP4K FPGA Logic Cells – 3,520 logic cells Memory 80 Kbits of embedded Block RAM (EBR) Distributed RAM: 640 bits 2x hardware I2C blocks and 2x hardware SPI blocks 26 I/Os for customized interfaces […]

PicoQuake USB vibration sensor is based on the RP2040 MCU and the ICM-42688-P vibration sensor

picoquake usb vibration sensor

The PicoQuake is a USB vibration sensor with a MEMS accelerometer covering a wide range of vibrations. It is capable of capturing vibrations in the low-frequency range (tall buildings, bridges) to the high-frequency range (motors, industrial machinery). It can operate as a standalone device and connect to a computer via a USB cable. Furthermore, it is based on the Raspberry Pi RP2040 microcontroller and uses a low-noise MEMS inertial measurement unit, the TDK InvenSense ICM-42688-P, which combines a 3-axis gyroscope and a 3-axis accelerometer. The low-noise IMU sensor used enables the PicoQuake to profile vibrations of very low magnitude. The PicoQuake sensor is a product from Slovenian maker, PLab, just like the FOCn driver module we took a look at recently. Potential use cases for the PicoQuake include optimizing brushless DC motor vibrations (important in small mobility products such as electric bikes and scooters), tracking trackpad clicks, smart home automation, […]
