The smallest module intended for installation in final products. Can be also used for evaluation after adding extra components like programming interface, bootstrapping resistors and break out headers.
The ESP-WROOM-32, measuring 25.2mm x 18mm only, contains the ESP32 SoC, flash memory, precision discrete components, and PCB antenna to provide outstanding RF performance in space-constrained applications.
The ESP-WROOM-32 pinout is optimized, since peripheral IO pads are grouped and led out to facilitate application board design with minimal external trace routing, thus making the application even more compact.
