NodeMCU ESP8266 Multipurpose Custom PCB - Breakout Board

Currently still Work in Progress - ...problably room for some more improvements....

Small Footprint, with standard headers usefull with Tasmota, ESPHOME & Home Assistant integration, with almost all IO available and standardized

• Vin Connector can be standard 2 pin or Screw terminal (preferably 5V, but Nodemacu should be ok up to 9V)
• D3 (Io0=Flash button) pin available for external button
• D5 for Sensor : DS18B20 or Similar ( if needed 4k7 external Pullup with Jumper)
• D6, D7, D8 available with selectable 3.3v or Vin power line
  • for Relay , Switch/Button , PWM (or any thing you might want to connect)
• Analog A0 (With 3.3V or Vin Power)
• D0-D1-D2 pins for RGB LED (Common Cathode or common Anode) or available for any other use case
• D1-D2 dualconnector I2C interface
• D4 for WS2812S (Default WLED pin) with Vin Power (use 5V)
• TX-RX pins for TTL
• SPI connector (MISO, MOSI, ...) en HW_SPI ou preferably on D0-D1-D2 Header
• Vin Connector can be either 2 pin or Screw terminal
• status LED for 5V Vin power and 3.3V from the NodeMCU

populate connectors as you need, you can use 90°angle pins to keep low profile if you have only a few ones
