The circuit and PCB have been produced and tested and basic code is available on github. See the project site on hackaday.io for more information about the project.
Larger 4 digit Serial 7 Segment display which has capability of communicating through SPI / I2C / serial TTL inputs. Smaller version is basic display board with 0.56" display and LEDs for colon and Apos. Larger board is based on same basic design but it adds ports for DS1307/DS3132 RTC boards, ESP8266-01 or 12E/F, DHT11/22 enviromental sensor, LDR light sensor and extra status LED's. Unused pins f...
ESP12F based board with 4 relays, DHST and/or LM35 temperature sensor(s) for Local or remote temperature measurment. Sockets for clock based modules based on DS1307 or DS3221 clock chips for time tracking. Additional I2C ports provide expandability to I2C displays or other sensors.
Great platform for building web based switches and monitoring temperatures and other sensors and login with RTC chips...
NodeMCU ESP8266 Multipurpose Custom PCB - Breakout Board
**Currently Work in Progress - my First EDA Project.... might even not work**
Small Footprint, with standard headers usefull with Tasmota & Home Assistant integration
- Sensor : DS18B20 or Simular ( if needed 4k7 external Pullup with Jumper)
- Relay with 3.3V or Vin Power
- PWM or other In/Out pin that could be needed)
