Universal 40-Pin ZIF Programmer

The GQ PRG-115 GQ-4X V4 is a true-USB Willem programmer designed for engineers and hobbyists who need to read or write a wide range of serial flash and EEPROM devices. Its robust enclosure houses a high-quality 40-pin ZIF socket that accepts chips directly or through the included TSOP32 adapter. The unit draws both power and data from a single USB connection, making it suitable for bench and portable use.

Includes 20 mm TSOP32 ZIF Adapter

The supplied ADP-021 adapter fits 20 mm TSOP32 packages and plugs into the main 40-pin socket, letting you program surface-mount flash chips such as the W25Q256 without soldering. This combination covers the specific package width that many laptop BIOS and IoT modules use. Without the adapter the programmer cannot address TSOP32 devices directly.

Driver-Free USB Setup on Windows XP Through 11

The programmer uses a native USB interface that Windows XP, Vista, 7, 8, 10 and 11 recognise without extra driver installation; the GQ-USB software handles device selection and voltage control automatically. A common issue is inserting the chip or adapter with the wrong orientation — always align pin-one markers before locking the ZIF lever. Keep the software updated to maintain support for newly added device IDs.

Questions about this item

How fast does the GQ-4X V4 programmer actually write a 256 Mbit chip compared with older Willem models?

The manufacturer states exponentially increased speed up to 20 times faster than previous Willem programmers, so a 256 Mbit device programs in a fraction of the former time.

What does the True-USB interface provide for data and power on this GQ-4X V4 unit?

The True-USB port handles both data transfer and power supply, removing the need for an external AC/DC adapter while keeping full programming speed.

Will the ADP-021 TSOP32 adapter fit a 20 mm TSOP-32 package on the 40-pin ZIF socket?

Yes, the ADP-021 is a 20 mm TSOP32 ZIF adapter designed to plug directly into the programmer's 40-pin ZIF socket for that exact package.
