![]() Most of the time, you’ll want to use an ESP32 development board. ![]() Using ESP32 bare chips is not easy or practical, especially when learning, testing, and prototyping. However, the “ESP32” term is also used to refer to ESP32 development boards. ESP32 Development BoardsĮSP32 refers to the bare ESP32 chip. The ESP32 is a bit more expensive than the ESP8266.įor a more detailed analysis of the differences between those boards, we recommend reading the following article: ESP32 vs ESP8266 – Pros and Cons.The ESP32 is dual-core (most models), and the ESP8266 is single core.The ESP32 supports Bluetooth while the ESP8266 doesn’t.The ESP32 supports analog measurements on 18 channels (analog-enabled pins) versus just one 10-bit ADC pin on the ESP8266.The ESP32 comes with more GPIOs with multiple functions.While the ESP32 can cost around $6 to $12, the ESP8266 can cost $4 to $6 (but it really depends on where you get them and what model you’re buying). Additionally, the ESP32 comes with touch-sensitive pins that can be used to wake up the ESP32 from deep sleep, and built-in hall effect sensor.īoth boards are cheap, but the ESP32 costs slightly more. The ESP32 adds an extra CPU core, faster Wi-Fi, more GPIOs, and supports Bluetooth 4.2 and Bluetooth low energy. ![]() What are the main differences between ESP32 and ESP8266 boards? Previously, we mentioned that the ESP32 is the ESP8266 successor. Main Differences Between ESP32 and ESP8266
