這是一個基於 ESP32 的 LED 點矩陣顯示專案,整合了 WiFi 網頁設定、RTC 時間顯示、以及條碼掃描器輸入功能,適合用於創客空間或資訊看板。
KiCad Esp32 LotNoDisplay is an open-source printed circuit board by Chihhao, from the Chihhao/ESP32-MAX7219-LED-Matrix-Display repository on GitHub. It is a 2-layer board of 57.2 × 52.1 mm with 18 parts on 40 nets, routed with 121 tracks and 2 vias.
It is built around the NODEMCU-32SLUA and BSS138. Its parts include 5 resistors, 5 connectors, 2 transistors, 1 capacitor and 1 IC. It belongs with the radio and wireless boards and the ESP32 and ESP8266 boards of this library.

Antes de desarrollar el sistema final, realizamos una etapa de exploración donde investigamos y experimentamos con las siguientes tecnologías:


bytecod3/lora-life-jacket
Electronic device for life jackets with LORA data transmission

hopkinskong/eie553-iot-hardware
ESP32 IOT Smart Lock Device Hardware Schematic and PCB used in the course "EIE553 Security in Data Communication".

2026MakerClub/PCB
projects with pcb, custom and commonly used schemes, footprints...etc.

ANTzacalie/termo-pro-esp32
Full-featured smart thermostat built on the ESP32 platform.

It measures 57.2 × 52.1 mm and has 2 copper layers, 1.6 mm thick.
18 parts, built around the NODEMCU-32SLUA and BSS138. 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.
From the Chihhao/ESP32-MAX7219-LED-Matrix-Display repository on GitHub, at the commit this page was made from: the board is KiCad/KiCad_Esp32_LotNoDisplay.kicad_pcb and its schematic KiCad/KiCad_Esp32_LotNoDisplay.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask Chihhao before reusing the design.
