Description
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 Tasmota Template: '{"NAME":"NodeMCU_Home","GPIO":[----tbd------],"FLAG":1,"BASE":32}'
