This controller 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. Due to limitations/restrictions, these do not 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 with TRRS cables, this can result in breaking the controller(s).
