Temperature Control Board

This is a control board for a toaster oven reflow project. It will use the following major parts:

ESP32 module for processing (wifi / bluetooth maybe?)
MAX31855 to interface with the thermocouple
SD Card interface
I2C interface for OLED display
UART for debug / programming (microusb?)
Extra IOs and interfaces available for future uses of this board

Questions

How big is the Temp Control Board PCB?

It measures 111.8 × 50.8 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Temp Control Board use?

39 parts, built around the ESP-WROOM-32D, FT232RL-REEL-S, MAX31855KASA+T and AZ1117EH-3.3TRG1. 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 Temp Control Board KiCad files?

From the mcupka/Temperature_Control_Board repository on GitHub, at the commit this page was made from: the board is Temp_Control_Board.kicad_pcb and its schematic Temp_Control_Board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Temp Control Board design in my own project?

Its repository states no licence, so its author keeps all rights: ask mcupka before reusing the design.
