Click the icon and select your new .bin or .hex firmware file. Click the Write IC (Program) button.

Commonly used for motherboard UEFIs, router firmware, and laptop BIOS chips.

⚡ CH341A defaults to 5V – use 3.3V adapter for 3.3V-only chips.

: Getting started is straightforward. The software is often distributed as a "green version," meaning it doesn't require a complex installation process and can be run directly. For CH341A users, the necessary drivers are typically included in the software package within a Drivers/CH341A subdirectory. Running the included SETUP.EXE file will install the drivers, making the programmer ready for use.

NeoProgrammer is an essential tool in the arsenal of any hardware enthusiast, but NeoProgrammer 2.1.0.19 stands tall as a community favorite.

The flexibility of Neo Programmer 2.1.0.19 makes it a Swiss Army knife for electronics repair. It natively interacts with the following families: Chip Family Common Use Case Example Part Numbers Computer monitors, TV mainboards, small appliances 24C02, 24C16, 24C512 25 Series (SPI) Motherboard BIOS, router firmware, GPU VBIOS W25Q64, MX25L128, GD25Q32 93 Series (MicroWire) Automotive odometers, immobilizers, older electronics 93C46, 93C56, 93C86 95 Series (SPI EEPROM) Automotive ECUs, airbags, industrial machinery 95040, 95160, 95640 Step-by-Step Guide to Flashing a Chip

Flashing a BIOS or EEPROM chip demands a strict operational sequence. Failing to follow these steps can cause verification errors or, worse, completely burn out a patient chip. Step 1: Install the Correct Drivers
