Overview
PillPCB is an open-source printed circuit board by andreq, from the andreq/iSpindel-Gravitymon-Pill-PCB repository on GitHub, published under the GPL-3.0 licence. It is a 2-layer board of 120.6 × 29 mm with 13 parts on 13 nets, routed with 70 tracks and 12 vias.
It is built around the WEMOS D1 MINI, DS18B20 and TP4056A, with the BAT43 among its other parts. Its parts include 4 ICs, 3 resistors, 1 diode, 1 connector and 1 switch. It belongs with the ESP8266 boards of this library.

README
README.mdiSpindel Gravitymon Pill PCB
A PCB used to build an iSpindel or GravityMon hydrometer that fit into a popular brand Pill casing instead of a PETling container.
Compatible with D1 Mini, C3, S2 and S3 mini esp board.
Building tips
Use the same components as most iSpindel PCB found online.
Remove the pin header plastic on the D1 mini (or equivalent) pins.
The D1 Mini need to be soldered as close as possible to the Pill PCB (between 1.5 to 1.9mm spacing between both board; Less is better).
The battery holder metal tabs need to be cut slightly to fit on the Pill PCB smaller pads.
Follow iSpindle build instructor for most of the other parts.
Only install the 470k voltade divider resitor for Esp32 based boards (C3, S2 and S3 mini).
The switch lever should be far away from the Pill casing, but might need to be shortened depanding on your switch.
THIS IS A WIP !!!
The latest PCB itteration was not produced yet, but should fit in a Pill casing.
My initial prototype needed a bit of sanding, will update as soon as first rev is tested.
I've only tested with a D1 mini, but the schematic and pcb fit Gravitiymon requirements for C3, S2 and S3 Mini.

Questions
How big is the PillPCB PCB?
It measures 120.6 × 29 mm and has 2 copper layers, 1.6 mm thick.
What parts does the PillPCB use?
13 parts, built around the WEMOS D1 MINI, DS18B20, TP4056A and BAT43. 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 PillPCB KiCad files?
From the andreq/iSpindel-Gravitymon-Pill-PCB repository on GitHub, at the commit this page was made from: the board is KicadPillPCB/PillPCB.kicad_pcb and its schematic KicadPillPCB/PillPCB.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the PillPCB design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
