Ch341a V 118 May 2026
The modern gold standard. ASProgrammer natively supports the CH341A v 1.18 with no configuration required. It supports a massive database of chips up to 128MB.
The CH341A is a popular, low-cost USB interface chip used for:
Version 1.18 typically refers to a widely circulated build of a graphical flashing software (often called CH341A Programmer.exe or similar) used with 24/25 series EEPROM/Flash.
A fork of ASProgrammer with enhanced chip detection. The v 1.18 works flawlessly here. Ensure you select "CH341A" as the programmer type. ch341a v 118
Great for the price, but the voltage issue on v1.18 makes it a “buyer beware”. If you can get a v1.5 or add a regulator, it’s 4.5/5.
The CH341A V1.18 is a classic version of the widely popular, budget-friendly USB programmer used for flashing BIOS chips, EEPROMs, and SPI flash memory. While newer hardware revisions like V1.7 have integrated more features, the V1.18 software and driver environment remain a foundational tool for technicians and hobbyists repairing motherboards, routers, and LCD monitors. 1. What is the CH341A V1.18?
The CH341A series is a family of USB-to-serial/parallel adapters that can interface with a variety of memory chips. The modern gold standard
Hardware: Often referred to as the "Black Edition," this version typically supports 24 series I2C EEPROMs and 25 series SPI Flash chips.
Software V1.18: This specific software version was one of the early stable releases for the Chinese-developed CH341A programmer application. While it is slower than modern alternatives like AsProgrammer or NeoProgrammer, it is still frequently bundled with the device. 2. Essential Setup and Drivers
To use the programmer, you must install the correct drivers to ensure your PC recognizes the device via the USB port. Go to product viewer dialog for this item. Version 1

The "CH341A V.118" refers to a specific version of a popular programmer device used for flashing or modifying firmware on various types of chips, particularly EEPROM (Electrically Erasable Programmable Read-Only Memory) chips, and other programmable devices. The CH341A programmer is widely used in electronics and embedded systems development for tasks such as updating firmware, modifying device settings, or even fixing certain types of hardware issues.
On v1.18, look for a 3-pin jumper named "3.3V / 5V". In some revisions, this jumper only changes the VCC voltage fed to the ZIF socket pin 20. The logic signals on pins 1-19 remain at 5V unless the board includes level shifters.
Critical warning: If your CH341A v1.18 lacks active level shifters, your 3.3V chip will receive 5V on its data pins despite VCC being 3.3V. This slowly destroys the chip. Verify your board using a multimeter: measure voltage between GND and pin 5 (DI) when the software sends a high signal. If you read above 3.6V, your board is unsafe.
