Great deal for what it was intended for. ### ⭐⭐⭐⭐⭐ Worked for Programming my W25Q64BVAIG *by C***X on June 28, 2023* I needed to reflash the BIOS on my motherboard to test out some BIOS Mods to enable ReBAR. My motherboard uses a socketed W25Q64BVAIG. This programmer worked extremely well with "AsProgrammer_2.1.0.13_fix" to reprogram the chip after installing the driver present in that package. ## Frequently Bought Together - HiLetgo CH341A STC Flash 24 25 EEPROM BIOS Writer USB Programmer SPI USB to TTL - ELEGOO 120pcs Multicolored Dupont Wire 40pin Male to Female, 40pin Male to Male, 40pin Female to Female Breadboard Jumper Ribbon Cables Kit Compatible with Arduino Projects - Antrader Breadboard Jumper Wires 40 Pin 10CM Female to Female for Raspberry Pi --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ph/products/80306690-hiletgo-ch341a-stc-flash-24-25-eeprom-bios-writer-usb](https://www.desertcart.ph/products/80306690-hiletgo-ch341a-stc-flash-24-25-eeprom-bios-writer-usb) --- *Product available on Desertcart Philippines* *Store origin: PH* *Last updated: 2026-08-03*
