Essential components – sensors and development boards
In the ESP32 series, we have a wide collection of development boards, which vary in size and pins. In this chapter, we are using Seeed Studio’s latest development board, the XIAO ESP32C3, as it’s very compact and smaller in size than other boards, and of course, cheaper and is suitable for 5V as well as 3.3V. The following figure is the pin layout diagram of XIAO ESP32C3.

XIAO ESP32C provides multiple pins for digital input/output. In the previous ESP series board, we found only one analog pin, but on this development board, we have four analog pins, which removes the biggest hurdle while developing a solution that uses multiple analog pins. With previous ESP series boards, we used ADS1115/ADS1015 for extra analog pins, so this development board will save us some bucks as we will get four analog pins by default on the development board...
