Universal Programmer with 40-pin ZIF Socket

The GQ PRG-108 GQ-4X V4 is a True-USB Willem programmer built around a high-quality 40-pin ZIF socket. It ships with an ADP-019 PSOP44-to-DIP32 adapter and a USB cable that handles both power and data. The unit targets engineers and hobbyists who need to read or write flash, EEPROM and microcontroller devices in DIP or adapted SMD packages.

Sustained Programming Throughput

Fast-mode SPI and JTAG support keep transfer rates high during long batch operations rather than only in short bursts. The dual power architecture draws from USB or an external AC/DC source with automatic voltage control, so the programmer maintains stable timing across extended sessions without throttling or manual jumper changes.

Plug-and-Play Setup with Adapter Handling

Driver installation covers Windows XP through Windows 11 on both 32-bit and 64-bit editions, and the GQUSB software updates automatically for life. The ZIF socket eliminates DIP switches, but users must still seat the ADP-019 adapter precisely; a misaligned pin 1 is the most common cause of failed reads on 44-pin PSOP parts.

Questions about this item

How much power does the USB port supply to the GQ-4X V4 programmer during long sessions?

The programmer draws both data and power from a single USB cable, with dual supply capability that adds automatic voltage control from an AC/DC source when needed.

Which adapter is required to program a 29F400 PSOP44 chip with this unit?

The included ADP-019 PSOP44-to-DIP32 adapter plugs into the 40-pin ZIF socket so the 29F400 can be programmed directly.

Will the GQ-4X V4 software run on a Windows 10 64-bit laptop alongside legacy XP tools?

Yes, the GQUSB software supports Windows XP through 11 in both 32-bit and 64-bit editions, so it coexists with older XP-based utilities.
