Neoprogrammer is a software utility used for programming and configuring microcontroller-based devices and EEPROM/flash memory via USB-to-serial adapter chips such as the CH341A. This paper documents Neoprogrammer versions 2.1 and 0.19 in the context of using the CH341A interface: features, architecture, supported devices, driver and hardware considerations, wiring and usage with CH341A-based programmers, example workflows, troubleshooting, limitations, and security/privacy considerations. ✅ – It’s not perfect, but it’s shockingly

NeoProgrammer 2.1 transforms the CH341A from a "toy" into a reliable tool. It resolves the biggest pain point of these programmers: poor software support. If you are struggling to read a chip with the default software, download this immediately. This paper documents Neoprogrammer versions 2

Click the "Detect" (Magnifying Glass) button. The software should identify the chip's manufacturer and ID.

Always follow this exact four-step order to prevent unrecoverable data loss: : Click Read IC to copy the current corrupted firmware.
