The nodeMCU and the WeMOS use same UART chips and drivers as the UART cables and boards. Depending on your board you have to install the CH340G drivers or CP2102 drivers. Identify by reading the marking on the chip near to the USB connector. Connecting UART to ESP. Again, those using the nodeMCU or WeMOS D1 mini may skip this paragraph. WeMos D1 (esp8266): i2c shield to manage encoder, multiple buttons, and LEDs For fast prototyping, I will create a set of shields for the WeMos D1 mini; the first is a service board with integrated pcf8574 IC, an encoder, and five other pins to use as input or output. Hi Blynkers, I wanted to show a small set-up using the ADS1115 with the Wemos Mini D1. This is not a “project” by itself, I posted several photos and more details in the forum a few months ago but the info was a little bit disordered so I think it’s a good idea to post all info together… I guess it could be useful in order to spread the world about Blynk ☺… -Description: The The D1 mini Pro is also designed to allow Wemos compatible shields to be plugged into the board in a similar way to the Arduino development board platform, which greatly expands its capabilities. There is already a large range of compatible shields available and these can also be purchased via our website. Dears, Theoretically I have a Wemos_d1_mini32 board. And I want to use the following adc pins: adc2_7 and adc2_2 according with the following scheme that I find in internet: According wiht the image there are 16 adc pins available for this board… But is impossible to select in ESPhome. Without errors I only can select the following adc pins: A0, A3, A4, A5, A6, A7 with the following code WEMOS D1 MINI ESP32 Contents. WEMOS D1 MINI ESP32. Hardware. Configuration. Uploading.

Introducing BH1750 Ambient Light Sensor. The BH1750 is a 16-bit ambient light sensor that communicates via I2C protocol. It outputs luminosity measurements in lux (SI derived unit of illuminance). It can measure a minimum of 1 lux and a maximum of 65535 lux. The sensor may come in different breakout board formats. JqkK.
