AngstromIO – A tiny 9.0 x 8.9 mm ATtiny1616 board that fits on top of a USB-C connector
Dieu-de-l-elec's AngstromIO is an incredibly tiny open-source development board based on Microchip's ATtiny1616 MCU. Measuring just 9.0 x 8.9 mm, the board is barely larger than the edge-mounted USB Type-C connector that powers it, making it ideal for highly space-constrained embedded projects. Despite its tiny footprint, AngstromIO packs a QFN20-packaged ATtiny1616 MCU, two addressable SK6805-EC15 RGB LEDs, and includes access to various usable GPIOs, including I2C, UART, and UPDI for programming. AngstromIO specifications: MCU – Microchip ATtiny1616 8-bit AVR microcontroller @ up to 20 MHz with 16KB flash, 2KB SRAM, 256 bytes EEPROM USB – 1x USB Type-C port (power only, no data lines connected to the MCU) Expansion via solder pads UPDI pin for programming I2C (SDA, SCL) 2x GPIOs (PB2/TX, PA3) 5V and GND Misc – 2x SK6805-EC15 addressable RGB LEDs Power Supply 5V via USB-C port Ultra-low power consumption (down to 200nA in power-down mode) Dimensions – 9.0
Open-source hardware USB to GPIB adapter connects legacy GPIB/IEEE-488 instruments to modern hosts
XyphroLabs's UsbGpib is an open-source hardware, inexpensive, and portable USB to GPIB adapter aiming to provide "access to legacy GPIB/IEEE-488 instruments using contemporary hardware and software, with a focus on accessibility, openness, and ease of integration into current workflows". Initially developed by Hewlett-Packard in the late 1960s/early 1970s, GPIB (General Purpose Interface Bus), also known as IEEE-488 or initially HP-IB (Hewlett-Packard Interface Bus), is a short-range digital communications bus standard designed for connecting and controlling programmable electronic test and measurement instruments such as oscilloscopes, multimeters, and power supplies to computers or controllers. The UsbGpib project helps connect GBIP-compliant equipment to modern host computers with a USB port. UsbGpib key hardware features and specifications: Microcontroller - Microchip ATMega32U4 8-bit AVR microcontroller for 5V I/O compatibility USB - USB Type-C port with full USBTMC (USB Test and Measurement Class) support 24-pin GPIB interface - Fully IEEE-488.1 and IEEE-488.2 enabled, including service request
