About The Project
TC Logger Device is a simple thermocouple USB reader: help you to measure any proccess you need using the USB protocol an a simple software developed in Python. The project was chosen to test the USB communication, explore the interface PC-Embedded system. The project is able to use two thermocouple at the same time and share the data to the computer at a speed of 5Hz. (5 samples per second). The main microprocessor is the PIC18F14K50.

Questions
How big is the ThermoDeviceLogger PCB?
It measures 40 × 30 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ThermoDeviceLogger use?
33 parts, built around the PIC18F14K50-I/P, MAX31855KASA+, TC1108-3.3VDBTR and ZLLS410TA. 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 ThermoDeviceLogger KiCad files?
From the makingdevices/TC-Logger-Device repository on GitHub, at the commit this page was made from: the board is old/Kicad/v1/ThermoDeviceLogger/ThermoDeviceLogger.kicad_pcb and its schematic Kicad/V1.2b/ThermoDeviceLogger/ThermoCouple.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ThermoDeviceLogger design in my own project?
Its repository states no licence, so its author keeps all rights: ask makingdevices before reusing the design.
