TinyLlama x86 retro computer uses the Raspberry Pi Zero 2 W as a MIDI synthesizer

The TinyLlama x86 retro computer board is designed to run DOS games on a DM&P Vortex86EX 32-bit x86 processor and integrates a MIDI synthesizer based on Raspberry Pi Zero 2 running MT32-Pi firmware. Growing up playing games on 386/486-era computers, Eivind Bohler looked for similar recent hardware to play DOS games and after discovering the 86Duino x86 Arduino-compatible board, he decided to use the SOM-128-EX module powering the board to create the TinyLlama board with a Sound Blaster Pro-compatible Crystal CS4237B sound chip and a MIDI synthesizer. TinyLlama specifications: D&MP SOM-128-EX system-on-module with Processor – DM&P Vortex86EX 32-bit x86 processor @ 60 to 500 MHz System Memory – 128MB DDR3 Storage – 8MB SPI flash Storage – MicroSD card socket Video Output – VGA up to 1024×768 @ 60 Hz using the Vortex86VGA module running off an x1 PCI-e lane Audio Crystal CS4237B all-in-one audio chip MIDI synthesizer with Raspberry Pi […]

EsPiFF board combines ESP32 module with RP2040 MCU in the Raspberry Pi 4 form factor (Crowdfunding)

The EsPiFF board may look like a Raspberry Pi 4 Linux SBC but it is equipped with an ESP32-WROVER WiFi and Bluetooth module together with a Raspberry Pi RP2040 microcontroller that acts as a co-processor. The goal here is to provide a Raspberry Pi 4 replacement for applications that require higher reliability and even 24/7 operation without necessarily needing the processing power and multimedia capabilities of the Broadcom BCM2711 Arm processor found in the Pi or the versatility of a Linux operating system. EsPiFF board specifications: Wireless module – ESP32-WROVER module with dual-core ESP32-D0WDQ6 microcontroller with 2.4 GHz WiFi 4 and Bluetooth, 8 MB PSRAM and 16 MB flash Co-processor – Raspberry Pi RP2040 dual-core Cortex-M0+ microcontroller @ up to 133 MHz with 16MB flash used to emulate the Raspberry Pi’s GPIOs on the 40-pin header Additional storage 2 KB of fast FRAM for permanent storage of process data. (faster […]

Radxa E25 modular 2.5GbE router supports WiFi 6 and 4G/5G cellular connectivity

Radxa E25 is a modular router with two 2.5GbE ports based on the Radxa CM3 Industrial (CM3I) system-on-module equipped with a Rockchip RK3568 quad-core Cortex-A55 processor, and optional support for WiFi 6 and 4G or 5G cellular connectivity. I got an early sample of the Radxa E25 carrier board in January, but the company has now refined the design with version 1.4 of the board and will launch the Radxa E25 as a complete router with an enclosure similar to NanoPi R5S and LinkStar H68K we’ve covered previously. Radxa E25 specifications: SoM – Radxa CM3I with Rockchip RK3568 quad-core Cortex-A55 processor @ 2.0 GHz with Arm Mali-G52, up to 8GB RAM, up to 128GB eMMC flash (250MB/s max), optional WiFi and Bluetooth Storage – MicroSD card socket, M.2 SATA 2242 SSD (multiplexed with 4G) Networking 2x 2.5GbE ports via Realtek RTL8125B 2.5 Gbps Ethernet transceiver (Tested by Radxa at 2.2 […]

Starfish PnP machine control board combines Raspberry Pi RP2040 MCU with TMC2209 motor drivers

StarFish Raspberry Pi RP2040 PnP control board

We’ve already seen the Raspberry Pi RP2040 MCU in a 3D printer controller board, so it should come as no surprise that the dual-core microcontroller also found its way into a Pick-and-Place (PnP) machine control board. Designed by Thea Flowers, the Starfish board leverages the RP2040 MCU capabilities to control three Trinamic TMC2209 motor drivers, MOSFET drivers to control DC vacuum pumps, two vacuum sensors, and offer RS485 and I2C connectivity for feeders and peripherals respectively.
