README
README.mdResistance Telemetry
🚧 Feature complete. Docs to be polished.
A compact sensor for a variable resistance that transmits data through BLE. A client program provides an interface for plotting and inspecting values on a desktop computer.
The device is physically compact (3.3 cm × 1.7 cm, around the size of the battery cell plus the antenna). It is powered by a LIR2016 cell and requires no setup on the computer side. Resolution is 24-bit, but no extensive calibration has currently been carried out. Designed for laboratory use, e.g. for e-skin gloves user studies.

Questions
How big is the ResSensor R2 PCB?
It measures 32.8 × 17 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ResSensor R2 use?
35 parts, built around the NRF24L01P-R, CS1237-SO, SPX3819M5-L-3-3 and AN2051. 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 ResSensor R2 KiCad files?
From the ayuusweetfish/Resistance-Telemetry repository on GitHub, at the commit this page was made from: the board is hardware/ResSensor_R2.kicad_pcb and its schematic hardware/ResSensor_R2.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ResSensor R2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask ayuusweetfish before reusing the design.
