Servos (optional)

Add a servo when your robot needs an arm or another moving mechanism. Both positional and continuous-rotation versions of these servo families are allowed.

There are different qualities available for all these motors and servos; however, even the lowest-quality ones can still be competitive in our league.

Battery

All three battery options below are legal for competition.

2S LiPo battery×1most power
Protected 2S 18650 battery pack with barrel jack×1compact
6×AA rechargeable NiMH battery pack×1simplest

The Alfredo NoU3 board takes a barrel jack, so choose the 18650 pack with a barrel plug; it connects directly without an adapter.

Here’s a guide for choosing which battery to use and buying the right charger, adapter, and safety gear.
