Overview
The PSH-C32 is a universal low-cost WiFi module designed by ITEAD, which adopts the highly integrated Wi-Fi chip ESP32 as MCU. Created by Espressif, the ESP32 is a new, low-cost SoC with Wi-Fi & dual-mode Bluetooth capabilities. ESP32 features at Xtensa dual-Core 32-bit Tensilica L108 MCU, operating at 160 or 240 MHz ( highest 250MHz), low-power consumption, multiple sleep modes and more. Compared to the previous generation ESP8266, ESP32 has more memory space and more I/O port for development. It is very ideal for wearable tech design.
