The In-Circuit radino32 WiFi combines an STM32L151 with the ESP8266EX SoC WiFi in a small form-factor EMC-compliant module.

The radino32 WiFi is the follower of the radino WiFi and offers improved CPU power, larger RAM-, Flash- and EEPROM-memories and expanded pin functionalities.

It is part of the radino-series, which provides full-Arduino-compatible wireless communication devices in a small form factor. All radino moules are pin-to-pin compatible.

The radino32 WiFi is being delivered preprogrammed:

  • running a ESP-based Webserver (with Java engine)
  • Default mode: Accesspoint "RADINO-WIFI", Key "12345678"
  • TCP/UDP service for UART-Bridge / WiFly  -> default IP =
  • all WiFi service runs ONLY on ESP !
  • STM32L151 is used as IO-machine for the ESP8266EX

We deliver the radino32 WiFi running a ESP-based Webserver (with Java engine) and telnet service (for UART bridge applications).
