faceplates/BulkyModem FP1/README.mdBulkyModem FP1
This is a faceplate, an inherently optional part of any build as it does not actually contain any active components. This faceplate mounts on the front of the device, and compared to the other options available, it is the shorter version 1. It is compatible with the following main projects:
It currently looks like this:
Footnotes
-
This means that it does not extend below the main PCB when installed, any faceplates installed on the bottom of device will not be covered up. Faceplate FP2 is the longer version of it. ↩

Questions
How big is the BulkyModem-32 Module PCB?
It measures 100 × 100 mm and has 2 copper layers, 1.6 mm thick.
What parts does the BulkyModem-32 Module use?
69 parts, built around the MAX232N, 74HCT244D, ESP32-WROOM-32 and 74HCT04D. 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 BulkyModem-32 Module KiCad files?
From the tebl/BulkyModem repository on GitHub, at the commit this page was made from: the board is BulkyModem-32 Module/BulkyModem-32 Module.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the BulkyModem-32 Module design in my own project?
Its repository states no licence, so its author keeps all rights: ask tebl before reusing the design.
