The ESP32-PICO-KIT fits into a mini breadboard. It is fully functional with the minimum number of discrete components, while it has all the ESP32 pins exposed.
- Complete up-to-date documentation is available.
- All instructions and commands presented work as described.
- Plentiful additional information and hardware documentation are available too.
- Applications for the ESP32-PICO-KIT can be developed on Windows, Linux or Mac.
Two cores and a radio
Like the ESP8266 the ESP32 has Wi-Fi but adds Bluetooth. It also has two 32-bit cores inside, making it extremely powerful, and providing all the ports and interfaces that the ESP8266 is lacking.
Oversimplifying things, one might say that the ESP8266 is a Wi-Fi controller that provides some I/O, whereas the ESP32 is a full-fledged controller that also has Wi-Fi.
The ESP32 exposes an ADC & DAC, touch sensor circuitry, an SD/SDIO/MMC host controller, an SDIO/SPI slave controller, an EMAC, PWM to control LEDs and motors, UART, SPI, I²C, I²S, infrared remote controller, and, of course, GPIO.
ESP32-PICO-KIT Development board V4
The ESP32-PICO-D4 is a System-on-Chip (SoC) integrating an ESP32 chip together with a 4 MB SPI flash memory in a tiny 7 x 7 mm package.
The ESP32-PICO-KIT is a breakout board for this SoC with an onboard USB-to-serial converter for easy programming and debugging.
Besides the board, you'll need a programming toolchain. Complete, up-to-date documentation from Espressif is available on the Read the Docs website.
