Soldering required

The nice!nano will NOT work with the Gherkin or Helix unless you leave the RAW pin disconnected from the board.

For split builds, you will need to purchase 2 nice!nanos. Due to limitations/restrictions, the nice!nano doesn’t play nice with other micro-controllers. 

Requires a 3.7v lithium rechargeable battery. We recommend this Battery as it fits under the header pins.

DO NOT use the nice!nano with TRRS cables, this can result in breaking the controller(s).
