IOT Cricket - Wi-Fi module (IOT cricket)

Very easy to use, ultra-low power Wi-Fi module, which can run directly on batteries. Designed for developers at all skill levels from advanced to those just starting to build IOT devices.

Cricket is a perfect choice if you want to build IOT end nodes such as sensors, alarms, buttons, switches,  etc. to report data and events instantaneously from remote locations. What is really cool is the ultra-low power feature, which will make your devices to run on single batteries for a very long time (for years in many use cases).

With Cricket you can connect various peripherals to Wi-Fi out of the box; send data and events either within your local network or to the internet. Simply attach a battery and peripheral(s) to Cricket and your device is ready to go.

Cricket comes with a native support of MQTT and HTTP POST / GET protocols that allow you to integrate your devices to a huge ecosystem of software and internet services such as e.g. IFTTT, Zapier, Blynk, Home Assistant, Node-RED,, Google Docs, Emails, Mobile Apps, etc.

Cricket works with all standard Wi-Fi routers and it doesn't require IOT hubs. No coding/programming is required as it comes with pre-installed software. You configure Cricket entirely over the air either from a smartphone or a laptop (without fiddling and troubleshooting toolchains). It can be done either locally (toe_device WiFi hotspot) or remotely from COTA cloud service (



* Ultra-low power, deep sleeep 0.5uA, true 0A (i.e. in a button device)

* Operates directly on batteries 1.0V-3.5V (AA, AAA, AAAA, ...)

* Sends data and events with ~3 seconds latency

* Configurable Real-Time Clock (RTC) for regular wake ups

* Configurable MQTT brokers

* Configurable secure / non-secure HTTP POST/GET requests

* Configurable a battery monitor

* Configurable Analog or Digital inputs (for sensors)

* Built-in configurable temperature sensor

* Local configuration (directly on a Cricket over captive portal / WiFi hotspot)

* Remote configuration from the Cloud (optional)

* OTA firmware updates


Few examples of what you can build with Cricket:


Endless possibilities to build broad range of devices which report data in various forms to the internet / services / smartphones
