Открыть PCB_V1.kicad_pro в KiCad 10. После обновления репозитория перечитать открытый проект с диска перед сохранением.

Состояние на 01.10.2026: плата 100×100 мм полностью разведена; 170 компонентов, включая четыре net-tie. ERC — 0 ошибок и предупреждений, DRC — 0 нарушений и несоединённых связей. Gerber и заказной BOM готовы. Локальная DFM-проверка: 0 FAIL, два предупреждения; повторный JLCDFM и проверка механики ещё не подтверждены. Открытые вопросы — DESIGN.md.

Основные параметры

Вход 24 В, XT60PW-M: 1 — GND, 2 — +24V; электронной защиты от переполюсовки нет.
PTC 24 В / 100 Вт, помпа 24 В / около 6 Вт, два четырёхпроводных вентилятора 12 В.
Свет: CH1 — панель 1,111 А; CH2 — две линейки параллельно, 0,465 А суммарно; общее управление яркостью. Возвраты разных каналов не объединять между собой или с GND.
ESP32-WROOM-32E, PCF8563T + CR2032, microSD, внешний SHT4x и поплавок.
Четыре слоя: 1 oz снаружи, 0,5 oz внутри; номинальная толщина 1,6 мм. Без крепёжных отверстий, разъёмы и microSD по краям, держатель батарейки снизу. Первые платы собираются вручную.

Questions

How big is the Cheap version PCB?

It measures 100 × 100 mm and has 4 copper layers, 1.61 mm thick.

What parts does the Cheap version use?

170 parts, built around the ESP32-WROOM-32E-N4, ST1S10PHR, ST1S14PHR and UCC27524ADR(UMW). 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 Cheap version KiCad files?

From the nikolajevs/ai repository on GitHub, at the commit this page was made from: the board is hardware/cheap-version/cheap-version.kicad_pcb and its schematic hardware/PCB_EU/Control.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Cheap version design in my own project?

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