Retro-uC Open Source MCU Brings ZX Spectrum, Commodore 64 Back to Life (Crowdfunding)

If you’ve started your computing experience in the early eighties, you’ve probably used a ZX Spectrum, Commodore 64, and/or Atari ST home computers. Those products are long gone, except for collectors, but thanks to chips4makers project’s Zilog Z80, MOS 6502, and Motorola M68K cores are coming back to life via Retro-uC open source microcontroller. As a bonus, developers also worked on Retrino, a board following Arduino Mega form factor, and featuring Retro-uC MCU, as well as Retro-uC ProtoPlus with the chip fitted to a large Perf+ 2 style prototyping board, and Retro-uC Breadboard which can be inserted into a standard breadboard. Retro-uC Microcontroller Retro-uC specifications: Open source microcontroller with a Z80, MOS 6502 and Motorola 68000 core 4 kB of on-chip RAM 72x 5V digital general purpose I/O pins JTAG interface for programming the device Optionally bootable from external I2C flash memory I/O pins that can select the enabled core […]

ANAVI Play pHAT OSHW Board Adds 8 Buttons, I2C Headers to Raspberry Pi Boards (Crowdfunding)

Leon ANAVI has been learning KiCad open source EDA suite in his spare time, and developed several Raspberry Pi (p)HAT add-on boards such as ANAVI pHAT Light to control LED RGB strips, or ANAVI Infrared pHAT to handle IR signals. All his boards are open source hardware, and come with source code, and decent documentation as explained in the two aforelinked reviews. Leon has now come with another variant of his open source hardware certified add-on boards with ANAVI Play pHAT designed for playing games on the Raspberry Pi 3 / Pi Zero W boards, or other boards with a 40-pin header, thanks to 8 buttons, and just like his previous designs, three I2C headers are also included to connect sensors. Key specifications and features of the board: Gamepad with eight buttons for playing retro games 3x I2C header for sensors EEPROM with device tree binary overlay OSHW Certification – […]
