It struggles with chips larger than 32MB due to addressing limitations of the CH341A chip itself. For 64MB or 128MB UEFI BIOS chips, you need a more advanced programmer.
Are you looking to one, or are you trying to fix a specific device ?
| Pros | Cons | |------|------| | ✅ Reliable 3.3V logic (good clones) | ❌ Many counterfeit v1.18 boards | | ✅ Faster programming (up to 15 MHz) | ❌ No native 1.8V support | | ✅ Works with flashrom, NeoProgrammer, AsProgrammer | ❌ Requires driver tweaking on Windows | | ✅ Exposes all CH341A pins (I2C, UART) | ❌ Lacks overcurrent protection | | ✅ In-circuit programming possible | ❌ Bulkier than FTDI-based programmers |
