Quick spec comparison - pick the right module
| Feature | ESP8266 (e.g., ESP-12) | ESP32 (e.g., WROOM) |
|---|---|---|
| CPU | Single-core 80/160 MHz | Dual-core up to 240 MHz |
| Wireless | Wi-Fi 2.4 GHz | Wi-Fi 2.4 GHz, Bluetooth 4.2 / BLE |
| GPIO / Peripherals | Limited ADC, fewer I/O | Multiple ADCs, DACs, SPI, I2C, CAN |
| Power use | Lower active current | More features, higher peak current |
When to pick ESP8266 vs ESP32
Choose ESP8266 for simple Wi-Fi sensors, small battery projects and tight budgets. Choose ESP32 when you need BLE, more ADC channels, or real-time tasks. For student labs where Bluetooth or multiple sensors are used, ESP32 dev boards reduce integration time.
Specification callouts & compatibility guidance
Check these critical specs before ordering: flash size (4 MB common), number of usable GPIOs (some pins reserved for flash or boot), antenna type (PCB vs external) and operating voltage. Match USB serial adapters (FTDI / CH340) to your board boot-mode wiring - incorrect wiring is the most common source of failure in new builds.
