Here is a handy checklist to go through to make sure the BlueRail board is sufficent for your loco.

SIZE (will it fit)?
The BlueRail board is 58.6mm x 28mm. Use this printable PDF to print out a copy of the board and verify it will fit:

CURRENT DRAW
If your loco has 2 AMPs or less maximum current draw it is probably a good candidate for this board (1.2 AMPs continuous). Related references:

* Overload Protection diagram
* Article about using board in larger gauges
* Article about measuring max current draw

MOTOR ISOLATED
If you are not sure if your motor is electrically isolated from the chassis, please refer to this article

LED LIGHTING
The BlueRail board supports LED lights. If your loco has full voltage incandescent lights, consider switching them to LED. When wiring LED lights be aware that the polarity of the wire leads must be correct.

DC, DCC OR BATTERY POWER
The BlueRail board will not work with AC power. If you wish to use the board on an AC powered track, consider adding an AC-DC converter as described in this article.

9 PIN JST HARNESS
The BlueRail board requires a standard 9-pin JST harness. If you do not have one, we have them available in our online store.

SMART DEVICE MUST SUPPORT BLUETOOTH 4
Does your smart device (phone/table) support Bluetooth 4? (Please read this Article)
