But some people may prefer the traditional IR air tower, especially when they're using Chu Pico design for a full-sized controller. So hereby I provide the IR air tower design, with a pair of air tower PCBs and the firmware support. -1. First, you need to order the PCBs, the gerber file is `Production\PCB\chu_air_v*.zip`.
