Overview
TransmitterV2 is an open-source printed circuit board by RobbeElsermans, from the RobbeElsermans/RC-Car repository on GitHub, published under the Apache-2.0 licence. It is a 2-layer board of 35.6 × 99.8 mm with 78 parts on 71 nets, routed with 573 tracks and 131 vias.
It is built around the ATMEGA328-AU, CH340C and AMS1117-3.3. Its parts include 25 capacitors, 23 resistors, 7 diodes, 7 connectors and 7 switches. It belongs with the AVR (ATmega, ATtiny) boards of this library.

code and files for my Tamiya Monster beetle
I'm refreshing my Tamiyan monster beetle with new 3D printed parts. The transmitter is lost by the years so I'm making a new "experimental" one.
Sadly my gearbox broke (a couple of times with 3D printed gear. maybe I'll try carbon or even hard TPU for more durability) so I'm planning on redesigning the gearbox.

Questions
How big is the TransmitterV2 PCB?
It measures 35.6 × 99.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the TransmitterV2 use?
78 parts, built around the ATMEGA328-AU, CH340C and AMS1117-3.3. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the TransmitterV2 KiCad files?
From the RobbeElsermans/RC-Car repository on GitHub, at the commit this page was made from: the board is RC Transmitter/PCB/TransmitterV2/TransmitterV2.kicad_pcb and its schematic RC Reciever/RC Reciever/RC Reciever.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the TransmitterV2 design in my own project?
Its repository publishes it under the Apache-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
