Last December, we wrote about XyphroLabs’s UsbGpib open-source hardware, affordable, and portable USB-to-GPIB adapter designed for legacy GPIB/IEEE-488 instruments and offering modern hardware and software.At the time, the UsbGpib V3 was also in the works with Ethernet (PoE) support, and the good news is that it’s now available, but named GPIBee. The less good news is that while V1 and V2 were both open-source hardware products (and still are), the GPIBee has been released as closed-source hardware for reasons we’ll explain below.GPIBee specifications:
Microcontroller – Not disclosed. But not the Microchip ATMega32U4 8-bit AVR MCU found in V2 since its USB interface is limited to 12 Mbps
Host interfaces
USB 2.0 (480 Mbps) Type-C port with support for four modes
Full USBTMC (USB Test and Measurement Class)
