For more than twenty years the DIMM form-factor (a.k.a. RAM stick) memory has been a consumable for laptops, personal computers and servers. Despite its widespread market availability and affordable pricing, the technological and engineering details has never been revealed to the public in an open source manner. Documentation and reference designs are not easily discoverable and understandable by the public. Complex PCB design requirements is another factor that has distanced startups, enthusiast and makers from attempting to design and manufacture DRAM modules.
The OpenDIMM project is an open source initiative to design the following three components for every DDR generation (starting from DDR4):
- Pinout Tester Board
- SPD Programmer (RPi Hat)
- Memory Stick (the DIMM module itself)
Welcome to pid.codes. If you’re a maker, hobbyist, or startup company producing your own USB device, you’ve probably discovered that you need a USB Vendor ID and Product ID to uniquely identify your device to computers. The USB-IF’s position is that the only way to do this is for each organisation to pay $6000 for a unique Vendor ID, which they may not share with other individuals or organisations.
For many makers and small companies, this is a prohibitive amount of money, and forces them to resort to workarounds, such as using other organisations’ VIDs without permission, or simply making up a VID and PID. These solutions make things worse for everyone, by damaging the assumption that a VID/PID combination is unique to a given device.
pid.codes seeks to solve this issue for anyone producing open-source hardware. We have been gifted a Vendor ID by a company that was issued one by USB-IF and has since ceased trading; they obtained the Vendor ID before the USB-IF changed their licensing terms to prohibit transfers or subassignments.
pid.codes will assign PIDs on any VID we own to any open-source hardware project needing one. To learn how to get a PID or PIDs for your project, see the how to get a PID page.
An open-source HDMI Keyboard/Video/Mouse (KVM) switch, which lets you switch two monitors and four USB devices between up to three computers. Theoretically, it should support HDMI 1.3a and up to 1920 x 1200 resolution. Anecdotally, it has been tested up to 2560 x 1440 at 75 Hz and it seems to work. I currently don't have the equipment to measure the signal quality or anything like that, and don't have a monitor with a higher resolution, so I don't know how far it can be pushed.
The base has a total of six HDMI inputs (three computers with two monitors each) and two HDMI outputs (for the two monitors). It also has four mini-USB ports (three computers and one for power), four USB host ports (to connect a mouse, keyboard, and anything else), and a connector that goes to the keypad.
The keypad has a 3x3 grid of buttons. Pressing the buttons lets you switch monitor 1, monitor 2, and the USB ports between the three computers. It connects to the base via a cable, and receives power over that connection.
M5Paper v1.1 is M5Stacks latest core device with a touch enabled E-ink display. Powered by the ESP32-D0WDQ6-V3 this is our first device to integrate a super sized 540*960 @4.7" E-ink display,which supports 16 gray scale levels. The display is a GT911 capacitive touch screen,which supports two point touch and a variety of gesture controls . Compared to a regular LCD,E-ink displays are easier on the eyes, which makes them a great choice for reading or viewing for longer periods. Other benefits are the low power consumption and the ability to retain the image even if power to the display is terminated. Integrated in the CoreInk are an multi-function button for operation, SHT30 temperature and moisture sensor, physical buttons and an TF-card (microSD) port for data storage.
Additionally the FM24C02 internal eeprom chip provided 2K-bit(256x8)-EEPROM can be used to store vital data even when the device is off. A 1150mAh lithium polymer battery keeps the device going for long periods and battery life can be further preserved by using the RTC(BM8563)to set the device into deep sleep and wake it up again when needed。Three HY2.0-4P expansion ports are included which allow for building complex projects using the existing sensors in the M5Stack ecosystem.

This is a small daughter board that fits into the socket of the "Sally" custom CPU in the Atari 800XL, 65XE and 130XE microcomputers (the RF shield must be removed, otherwise the daugher board won't fit inside). It replaces that CPU with a CMOS, modern, low-power, fully static, currently in production W65C02S CPU and some auxiliary logic.
The package contains the auxiliary logic chips, the capacitors, the resistances, 40 pin strip and the 4 layer board. Suitable W65C02S CPU is not included, you must search for one these, as recommendation, from trusted distributors.
The Retro-Printer Module is a small module ("HAT") designed by Retro Computer specialist, RWAP Software. The module plugs into a Raspberry Pi (or other Single Board Computer) to allow you to capture data from a centronics port on older (vintage) computers and equipment, converting it for electronic storage, or printing to any modern printer such as a USB or network printer. It connects to a standard parallel port and emulates a wide range of printer makes and models including Epson ESC/P, Epson ESC/P2, HP PCL3, HP PCL5, Printronix, Seiko and IBM.
Supporting both centronics and serial connections, you can easily capture printer data from a DOS program; a 1980s Home computer; an industrial lathe; test equipment; door entry system; or even PLC controlled equipment to a modern, low-cost printer. We emulate a wide range of different printer protocols and work closely with both home computer users and industry to offer a modern print replacement for dot matrix printers.
This makes the module ideal for both producing hard copies of printed output on modern printers, or for capturing data from old equipment; removing the need for legacy printers and enabling migration of data to modern systems and software.
There are two versions, a Centronics parallel port version and an RS232 serial printer version.
NEWPRINT/Multi is a Wi-Fi-enabled "virtual" printer adapter that connects to your computer's printer port and your local Wi-Fi network to send printer output to any device that supports a modern browser (iPad, Desktop PC, Mac, etc.) The NEWPRINT web interface can show printer output as plain text, hexadecimal values, Print Shop graphics (Apple II), or Apple IIgs GS/OS graphics printing. Text mode output does not (currently) understand special printer control codes used by most word processors (BOLD, multiple font sizes, Form Feed, etc.) The NEWPRINT web interface is available from any browser on your local Wi-Fi network at newprint.local. NEWPRINT uses the standard HTML WebSocket API so you can even write your own web-based or desktop interface for displaying and processing NEWPRINT output.
As long as the printer has a Centronics interface, you can plug it into this unit.
