BBQ Sensor
The 8 is a simple temperature monitor intended for BBQ/Smoker. It has 8 inlets that can be used with PTC or Pt100 probes. The BBSensor is run by a ESP8266 Microcontroller (NodeMCU Lua Lolin V3 Modul). The temperature can be delivered either via the display or network.

Questions
How big is the BBMini2 PCB?
It measures 88 × 50 mm and has 4 copper layers, 1.6 mm thick.
What parts does the BBMini2 use?
79 parts, built around the CP2104EK, ESP8266EX, LM2576S-5.0 and MCP3208-BI/P. 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 BBMini2 KiCad files?
From the TheUncleKai/bbsensor repository on GitHub, at the commit this page was made from: the board is hardware/Mini2/pcb/BBMini2.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the BBMini2 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).
