There are only four components: an Arduino Nano, a DS3231 RTC module, a SSD1306 128×64 OLED module, and a momentary pushbutton. ... An Arduino Nano is in charge of reading the sensors.

But the "Arduino Nano ESP32 small PCB" or connect directly to the Arduino Nano ESP32 pin is also probably 1 x PCB Nano ESP32 1 x Arduino Nano ESP32 with pins 1 x 1000 µF condensator 1 x 470Ω resistor ...

A RTC DS3231 can be attached for an accurate time when no WIFI is available. A LDR controls the light intensity. ... 1 x PCB Nano ESP32 1 x Arduino Nano ESP32 with pins 1 x 1000 µF condensator 1 x ...

The PCB manufacturing for the Arduino Nano currently places components on both sides of the board, requiring two operations for solder paste, pick-and-place, and reflow.

In this particular project, I contemplated a shield for Arduino Nano, which can gather weather-related information by a built-in BMP280 Temperature and Pressure Sensor, a photoresistor, and a ...
