PLEASE NOTE: The item you receive may not be the exact unit shown in the photos; however, it will be the same part number or a compatible interchangeable model listed above and in similar condition.
All items are pre-owned and may show normal cosmetic wear such as minor scratches, paint marks, fading, or missing stickers. These cosmetic differences do not affect functionality.
Understanding Part Number Suffixes
When purchasing a logic board, you may notice different characters at the end of the part number (e.g., 41AB050**-2**, 41AB050**-2M**, or 41AB050**-2G**).What they mean: These suffixes simply indicate the manufacturing date or hardware revision (such as a different brand of relay or a minor update to the circuit board layout).Compatibility: The suffix does not change the functions of the board. All boards within the 41AB050- series are 100% interchangeable and will work perfectly with your existing 315 MHz system.The Golden Rule: As long as your original board has the Purple Learn Button, any board from this series will be a direct, "plug-and-play" replacement regardless of the suffix.
