Graviton CH341A Programmer V1.7 1.8V Level Shift

SKU CH-M1FT-06TBP

A CH341A V1.7 programmer with integrated level-shift chip reads and writes 1.8 V, 2.5 V, 3.3 V and 5 V serial EEPROM and flash devices, plus KB9010-series EC chips.

  • Reads and writes 1.8 V chips directly with integrated level conversion chip
  • Programs 24, 25/26, 93, 45, 95 series plus KB9010, KB9012, KB9016, KB9018, KB9022 EC data
  • Open-source software lets you add chip types or modify source code yourself
  • Built-in infrared code measurement module and TTL self-check for quick diagnostics
  • Status LEDs show read/write and TTL activity at a glance

USB BIOS Programmer

The Graviton CH341A Programmer V1.7 is a compact USB device that reads and writes SPI flash and EEPROM chips directly from a computer. An integrated level-shift chip lets it handle 5 V, 3.3 V, 2.5 V and 1.8 V parts without external adapters. It targets repair technicians, hardware hobbyists and firmware developers who need low-level access to BIOS, EC or embedded-controller memory. Open-source host software allows users to extend the supported device list themselves.

Firmware repair and hobby use

Engineers who regularly reflash 24, 25, 26, 93, 45 or 95 series chips, or KB9010, KB9012, KB9016, KB9018 and KB9022 embedded controllers, will find the wide voltage coverage and built-in TTL self-test convenient. Buyers who need guaranteed vendor support, signed drivers or a ruggedised enclosure for production-line throughput should look at dedicated gang programmers instead. The tool also lacks a protective case, so it is less suited for rough field kits.

Plug-in operation with ZIF socket

Installation consists of plugging the unit into a USB port, launching the supplied open-source application and placing the target chip in the zero-insertion-force socket. The on-board status LEDs confirm power, read, write and TTL activity at a glance. Common issues include misaligned chip orientation, selecting the wrong device ID in the software list and loose USB connections that interrupt a write cycle. The Baidu-hosted manual requires an extraction code for access.

Questions about this item

What chip voltages does the 1.8 V level-shift support for direct reading and writing?

The integrated level conversion chip lets the programmer read and write 5 V, 3.3 V, 2.5 V and 1.8 V devices directly.

Will the 24-series and 25-series locking seats work with older 24Cxx and 25Cxx EEPROMs I already own?

Yes, the 24-series seat adds a strong pull-down resistor and the 25-series seat adds a pull-up resistor, both compatible with legacy 24 and 25 chips.

How can I verify the programmer is functioning correctly after I connect it?

Run the built-in TTL self-check and watch the read/write status LED and TTL status LED; both should light to confirm normal operation.
