CleO35-WIFI Module
1 Introduction
The CleO35-WIFI module is a Wi-Fi accessory for the
CleO series – the smart TFT display for Arduino.
Designed with an ESP-12S Wi-Fi module from Ai-thinker
using core processor ESP8266, the ESP8266 is among
the most integrated Wi-Fi chips in the industry.
Measuring just 5mm X 5mm, it requires minimal
external circuitry and integrates a 32-bit Tensilica MCU,
digital peripheral interface, antenna switch, RF balun,
power amplifier, low noise receive amplifier, filters and
power management modules all in one small package.
The CleO35-WIFI module comes with a standard 16 pin
0.5mm pitch FFC cable, suitable for connecting directly
to CleO35 modules or via the CleO_IO Shield to CleO50
modules enabling wireless communications to the
system.
As a plug in accessory to CleO it extends the CleO
modules capabilities to include wireless monitor and
control for smart devices around the home.
1.1 Features
The CleO35-WIFI consists of ESP-12S WIFI module
developed by Ai-thinker using an ESP8266. For the
full list of ESP8266’s features, refer to the ESP8266
