DIGITAL TOOL // ACOM

ACom Flasher

Install the bundled DMComm Arduino 0.4.4 firmware on supported Arduino and Bazjo D-Com boards. Flashing stays entirely between this browser and your USB device.

Preparing
1

Connect the device

Plug in one ACom or Arduino-compatible board by USB, then choose its serial port. Close Arduino IDE and serial monitors first.

No device selected

Select the board profile

Flash and verify

The flasher checks the board signature before writing, programs 128-byte pages, then reads every page back for verification.

Validating bundled firmware…

While flashing: do not unplug the cable, close this tab, lock the device, or let it sleep.

Cable, profile, and recovery guide

Use a USB data cable; charge-only cables cannot reach the bootloader. Select the profile explicitly because USB adapter names cannot reliably identify clone boards.

  • For Bazjo D-Com v2, try Nano New / Bazjo D-Com v2 first. If sync fails, reconnect and try Nano Old Bootloader.
  • A wrong board signature is stopped before firmware is written. Select the correct profile and retry.
  • If both Nano profiles fail, check the cable, USB driver, bootloader, reset wiring, and whether another app owns the serial port.
  • A successful result means every programmed page was read back and matched—not merely that the write completed.
