Overview
CrealityDryerV1 is an open-source printed circuit board by Ermakov, from the Ermakov/CrealitySpacePiAutomation repository on GitHub. It is a 2-layer board of 39.9 × 46.4 mm with 20 parts on 56 nets, routed with 469 tracks and 38 vias.
It is built around the ATMEGA328P-AU and SS14. Its parts include 6 capacitors, 6 connectors, 2 resistors, 1 IC and 1 diode. It belongs with the lEDs and displays boards and the AVR (ATmega, ATtiny) boards of this library.

README
README.mdCreality SpacePi automation and control module
This is PCB and Arduino IDE sketch for Creality Space Pi (Plus or not) automation.
Description:
- necessary the module itself and IDC10 female-male cable
- can be inserted into any Creality SpacePi dryer (double, single, built-in Creality CFS or not)
- other functions and cables are optional (backlights, external control and power are not required for operation, but can be connected additionally)
- the cable from the SpacePi display needs to be disconnected from the dryer board and inserted into the "display" socket on the module
- an additional IDC10 cable connecting between the module "mainboard" socket and the dryer board (power is supplied from the dryer board via this cable)
- RJ45 on the module connecting to any I2C master using a regular patch cord and provides data transfer in both directions, and also serves lighting (24V led strip) inside CFS or dryer
- two pin terminal block on the module used for connecting the led strip; pad J4 on the back of the module (via diode) used for supply 24 volts to the strip directly from CFS (without connecting a patch cord with external power)
Module/sketch features:
- interception of all signals between the display/buttons and the dryer board, the module sees the readings on the display and can control the dryer buttons
- automatic switching on SpacePi after power is supplied
- automatic switching on SpacePi drying mode to the values on the display when the module sees humidity above the set point (by default 30%, switching on for 4 hours, then a break of 4 hours, and so on)
- solving the problem with the E4 error (when the dryer does not reach the expected temperature within 10 minutes) by restarting the drying mode every 9 minutes (until heating to the working temperature)
- transferring data of temperature/humidity in the dryer via I2C as HTU21D sensor protocol
- any information from the dryer display (including an error), as well as pressing any buttons using special I2C commands (see the sketch)

Questions
How big is the CrealityDryerV1 PCB?
It measures 39.9 × 46.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the CrealityDryerV1 use?
20 parts, built around the ATMEGA328P-AU and SS14. 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 CrealityDryerV1 KiCad files?
From the Ermakov/CrealitySpacePiAutomation repository on GitHub, at the commit this page was made from: the board is CrealityDryerArduinoPCB(KiCad8)/CrealityDryerV1.kicad_pcb and its schematic CrealityDryerArduinoPCB(KiCad8)/CrealityDryer.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the CrealityDryerV1 design in my own project?
Its repository states no licence, so its author keeps all rights: ask Ermakov before reusing the design.
