What is the shot-dosing PCBA?

The shot-dosing PCBA is an accessory board designed to work with the Micra paddle signal path. It is intended to support target-yield and stop logic while keeping installation guided and reversible when the wiring direction and connectors are checked carefully.

What installation ability is needed?

Users should be comfortable powering down the machine, following connector orientation photos, checking cable direction, and doing a cautious first power-on test. If not, prepare an installer or contact support before ordering.

How does it connect to daily workflow?

After installation, the PCBA works with the S3 remote and, when configured, Bluetooth scale target-yield behavior. For the weighing side, read the Bluetooth scale auto-stop guide.

Does the PCBA require self-installation?

Yes. It requires basic DIY ability or an installer who can follow the Micra wiring and power-off installation notes.

Can the dosing PCBA firmware be updated like the remote?

It has its own C3 firmware path. Do not flash S3 remote firmware onto the C3 dosing chip.

What should I keep for support?

Keep the order number, installation photos, device symptoms, and any firmware version information.

  2. Power off and check the cable route, connector direction, and installation space.
  3. Install the adapter board, then run a controlled power-on and function test.
