I/O FPGA Glasgow Interface Explorer digital interfaces

What is Glasgow Interface Explorer?

Glasgow Interface Explorer is an open source multitool designed for hardware designers, reverse engineers, digital archivists, electronics hobbyists etc. Without additional active or passive components, it can be attached to most devices and provides extensive protection from unexpected conditions and operator error. You are not required with any programming knowledge. Of course, it will become more powerful with Python. 

The Glasgow hardware can support many digital interfaces,such as FPGA/CPLD Bitstream Programming Interfaces, radio, sensor and other interfaces. Also, the Glasgow Revision C board includes 16 input/output (I/O) pins with a peak 100MHz frequency, independent direction control, and independent pull-up/down resistors, grouped into two I/O ports compatible with 1V8 to 5V logic. Each I/O bank has a dedicated programmable linear voltage regulator and a dedicated sense ADC.


  • Standard Protocols

Communicate via standard UART

Initiate transactions via SPI or I2C

Receive I2C transactions

  • Logic analyzer generating VCD file for analysis with GTKWave or Sigrok
  • Read and write 24-series EEPROMs, 25-series Flash memories, ONFI-compatible Flash memories, parallel 27/28/29-series EPROMs, EEPROMs and flash memories,
  • Microcontroller/CPU Programming and Debugging Interfaces
  • FPGA/CPLD Bitstream Programming Interfaces for example program and verify XC9500XL CPLDs via JTAG
  • Radio Interfaces – Communicate using nRF24L01(+) radios, program nRF24LE1 and nRF24LU1(+) microcontrollers
  • Sensor Interfaces to measure data from temp
  • Display & Video Interfaces
  • Audio interfaces



Glasgow Interface Explorer is designed by 1BitSquared, it is currently in the crowdfunding stage in CrowdSupply. If you are interested in this flexible open source multitool, don't hesitate to give your support!
