iNode MCU USB - adapter with Bluetooth 4.1 and WiFi

Description

iNode MCU USB is a device with modifiable functionality that works under the control of the NodeMCU ESP32 system - the LUA programming language script interpreter. iNode MCU USB combines two wireless technologies: Bluetooth 4.1 and WiFi. For user safety, the Node MCU firmware is digitally signed and can only be replaced using OTA technology.

Users can write their own LUA scripts and place them on the device. The iNode MCU FFS application serves this purpose. The LUA free scripts with various functionalities are available to the user on the support site.

In the WebUSB version iNode MCU USB, it is possible to directly communicate from the LUA script with the Google CHROME browser. WebUSB is a kind of bridge between USB devices and browsers.
